Java script with demonstration. Web designer - useful links


Java Script It - useful program, which makes it easy to add effects and functionality to web pages. It includes a large library of ready-made applets, helping you avoid manually writing code for simple functions, and perhaps even do without learning JavaScript. This solution is indispensable assistant anyone Front End developer, especially a beginner. It is extremely simple and convenient to use.

Functional

So, let's imagine that you have created a web page using HTML and CSS, but suddenly decided to add some functionality to it that cannot be implemented in the language of cascading styles and, even more so, in a markup language (or it is simply impractical to do). For example, you need to “teach” the site to save Cookies or add a simple working form to it. Or maybe you just want to "play" with visual effects, but I have no desire to bother with Keyframe animation. In all the above cases, you can turn to Java Script It. The program offers ready code although not for all occasions, but for many. The applets in the local library are very cleverly divided into categories (effects, functions, and so on), which makes it easy to find the one you need.

Principle of operation

To get started with Java Script It, you need to load an HTML page into it. To do this, use the convenient file browser. After that, find the desired script in the library and double-click to “connect” it to the page. The program has a built-in browser in which you can preview changes made, but we would recommend using a third-party browser, since the standard solution does not support all modern web standards. Having achieved desired result can be exported ready project, consisting of HTML and JS files.

Flaws

The main disadvantage of Java Script It is that the program is only suitable for those developers who do not use a CMS to create their websites. That is, most likely, they are engaged in one-page and low-page websites. Also note that JSI has not been updated for quite some time, so it may experience compatibility issues with latest versions Windows.

Key Features
  • large library of applets;
  • “connecting” effects and functionality to an HTML page by pressing one key;
  • intuitive interface;
  • built-in browser for preview changes;
  • fast import and export.

Java (java) is a modern platform for complete and stable operation client-server applications. A huge number of web applications, commercial online services for shopping in online stores, tools for virtual communication and much more, in most cases, operates on the basis of the Java Runtime Environment.

Without installing this software, you are also unlikely to be able to participate in numerous online games via the Internet. Therefore, one of the most necessary applications Today, Java is considered to be for PC.

You can download Java for free for all versions of Windows on our website (link at the bottom of the article).

New versions of software are released quite often, so we recommend keeping an eye on updates and always installing latest version, otherwise you risk remaining a user of an outdated application that may not support new features of your favorite program or popular online service. The latest releases of the JAVA platform are developed taking into account modern system requirements, which allows you to create more productive and stable platforms for development and use, ensuring comfortable and reliable operation. So, for example, a new version is coming to replace java 7 32 bit (64 bit) for windows - java 8. Each new release has innovations necessary for modern programs and 8 is no exception.

In addition to using Java as a software platform for the software user, this technology is increasingly used in programming for writing applets (programs) as a basis for various applications or additional modules for them.

Currently, to create server applications that client Internet browsers work with, developers use this particular programming language, since it truly allows for fast and convenient operation of the client-server system.

The main potential of the platform:
  • unhindered access to database management systems;
  • using basic software to configure applications;
  • management and optimization of the memory used by the program occurs automatically;
  • full support for multi-threaded applications;
  • provides open and reliable access to services via the Internet;
  • Java can be downloaded for free for Windows, Linux, MacOS and other operating systems.
  • unlimited potential for use in the development of virtual online stores, games and other interactive services;
  • organizing work with HTTP requests and issuing responses to them using separate classes;
  • support for simultaneous operation is provided large quantity JAVA programs.
How does Java 32 bit / 64 bit work for Windows? The operation of the software is based on the use of the JRE runtime environment and the JVM virtual machine. Additionally, base platform classes and auxiliary libraries are used.
The JRE engine provides the ability to execute applets in an Internet browser.

The JVM is essentially an interpreter designed in such a way that the application (applet) is compatible with various devices and operating systems - in other words, the Java machine ensures that the java applet is cross-platform.

Advantages of Java: Any user can download Java Runtime Environment for free efficient work With different versions Windows OS starting from Windows XP. It guarantees high performance for computer games, online applications, as well as work with various emulators for mobile devices(mainly used for developing java applications and mobile games). Disadvantages of the platform: From time to time, user complaints are recorded about the insufficient speed of the application itself (in this case, try to update java to the latest version).

Java Runtime Environment is most suitable for fans of Internet games. Most often, gamers download Java in order to use all the capabilities and innovations of developers in games such as Minecraft and the like.
But even those who just like to stroll around the Internet will love Java users: modern developers web pages often use this programming language to create global Internet applications and online services.

Important note: if different versions of Internet browsers with different bit depths are installed on your computer (for example, one for 32 bit, the other for 64 bit), then for correct operation Java requires downloading and installing both versions of the program.

Java is an object-oriented programming language and an application software platform created on its basis. Java is an environment for launching websites, online stores, forums, remote banking, virtual navigation maps, educational programs, questionnaires and online games, as well as other specialized web applications. Often it is simply impossible to do without this software platform, but there is always the opportunity to download Java for free on a computer with Windows 10, 8.1, 8, 7, Vista, etc. The main difference between the Java project was that it made it possible to create software that does not require compiled for each processor architecture and operating system.

Short story development Java technologies and status today

Java was developed by Sun Microsystems in 1991-1995, and the technology was subsequently acquired by Oracle. Release new version Java was developed through the interaction of Oracle programmers with representatives of the World-Java eco-system, Open JDK and JavaCommunityProcess. Today you can download Java 64-bit or 32-bit for free for Windows 10, 8, 8.1 (for desktop PCs), 7 SP1, Vista SP2, Server 2008 R2 SP1 64-bit, Server 2012 and 2012 R2 64-bit to work with Internet browsers Explorer 9 and higher versions, as well as Mozilla Firefox. The Java software package consists of four software components: the JRE, which is responsible for executing applets, the Java virtual machine, which interprets the bytecode, base classes and auxiliary libraries. Today, the Java Runtime Environment can deploy server-side Java applications and establish a connection between the browser and the Java platform. It is also worth paying attention to free programs with similar functionality:Microsoft. NET Framework, plugin Microsoft Silverlight, Adobe Flash Player, Adobe Shockwave Player in the Platforms and Environments section.

Java compared to popular programming languages

The main advantage of Java is platform independence. The developers promise speed, durability, security and recommend the latter Java version download for free without registration from the official website. However, according to reviews and comments from IT specialists, applications in Java take up more memory, have lower performance and responsiveness, as opposed to their counterparts in C or C++. But Java has a number of advantages in the field of security and reliability compared to languages ​​such as C, C++, Python, Fortran, Ruby, PHP, JavaScript and others.

Advantages of platform-independent Java implementation

The developers claim that any Java applet runs perfectly on various devices running different operating systems. On almost any smart device it is possible to download Java for free and install it successfully, regardless of what operating system the device is running. This option is called not just cross-platform, but platform-independent implementation. The advantage of this way of operating programs is complete independence program code from OS and hardware. This feature allows Java applets to run on any virtual machine-compatible device.

The advantages of Java include:

Reliable and secure applications and games,
- work in multi-threaded mode,
- ideal functionality for network computing,
- powerful tools for launching network programs,
- reliable protection and encryption of information,
- direct access to web services,
- working with Java applets on the Internet,
- productive interaction with OpenGL and DirectX via Swing,
- GifWriter for working with animated GIF files,
- full Unicode support.

Java Security Organization and Updates

Java's impenetrable security system is due to the fact that application execution is completely controlled by the JVM. Excess of authority, such as unauthorized use of data or sending of information, is immediately stopped. The JRE's high level of security is maintained by maintaining a blacklist of certificates and JAR files. By default, you can only run verified applications with digital signature. For users previous versions It is recommended to remove all outdated software, download Java for free for Windows 7, 8, 8.1, 10, as well as outdated Vista and server Windows 2008 and 2012, and install the latest version on your computer. Outdated Java may have vulnerabilities that are unsafe. For supporting high level security updates should be installed regularly. Minor changes do not change the indexing, but use the word Update (letter u), but they are no less important. It is not surprising if you need to download the latest version of Java for Minecraft, Prince of Persia, Solitaire, Need for Speed, GTA, Zona, TequilaCat Book Reader, E-666 Supplement Database, Remote Banking or other latest software. Moreover, downloading Java for Minecraft and other Java games for free is simply necessary for quality video, the ability to access all settings and normal network gameplay.

How to install Java on your computer correctly

To properly install Java on a PC, you first need to uninstall everything. To remove outdated software you should use standard feature: Start - Control Panel - Uninstall a program. Next, you need to download Java for Windows for free from programmywindows.com, a 32- or 64-bit installation file, respectively, observing the bit capacity of the main browser, close all browsers and running programs. When everything is ready, you can start the installation, and when the installation is complete, restart your computer. If both 32-bit and 64-bit browsers are used on the computer, then both versions of Java (32-bit and 64-bit) must be installed for compatibility of Java modules with all browsers.

New generation browser. A simple and concise interface allows you to master the program in a few minutes. Safety, high speed work, flexibility and extensibility the main qualities inherent in Mozilla Firefox a completely free browser, perfectly localized by the Russian team. However, the developers will always be happy to accept a voluntary donation from you, which will go exclusively to development technical base project.

Colorful, interesting world Mozilla programs result of labor huge amount of people. The owner of this website appreciated all the advantages of the Mozilla Firefox browser when she began developing wap sites for mobile phones V XML format. It turned out that Mozilla Firefox not only supports this mobile standard on personal computer and correctly displays XML files with the .xhtml extension in Unicode UTF-8, but also has a built-in XML code error parser. Unlike a number of other browsers, Mozilla Firefox not only displays the correct error message about your code in Russian, accurate to the line number and character number in the line of code of the XML page, but also points with an arrow to the first erroneous place in your XML code.

If you are programming for mobile wap-Internet, it will be easier for you to work with it. Set the size of the visible page window in Mozilla Firefox as 240x320 px (horizontal x vertical), for example, using a picture of the same size and you will see how your wap site will look from a mobile phone.

http://www.denwer.ru
A gentleman's kit for a Web developer (“Dn.w.r” “Denver” almost like the name of the city) the most famous project of the dk Laboratory, a set of distributions (Apache, PHP, MySQL, Perl, etc.) and shell, used by Web developers (programmers and designers) to debug sites on a local Windows machine without the need to access the Internet. For Russian-speaking users, Denver will forever remain free. However, the Denver developers will be happy to accept any voluntary donation from you: it will be used to further improve this valuable and useful project.

Due to the use of a virtual disk, Denver looks like a “little Unix” from the inside: it has its own directory /home, /usr and even /etc. The various components and servers are arranged in a Unix-like manner. For example, /home contains virtual hosts, and /etc contains configuration scripts. All comments in the files are translated into Russian. You must get used to the idea that your “local server” is as good as any other located on the Internet. It contains sites (one or several), each of which has a specific name (you set it yourself). These sites are accessed as usual: You indicate in address bar full URL the usual http name of the site and the path to the document on it, but without Internet access. You will be able to work quite fully at local computer with your sites as through the Internet.

Denver is installed in a single directory and does not change anything outside of it. It does not write files to the Windows directory or the Registry. If you wish, you can even install two Denvers at once, and they will not conflict. If you launched Denver, then it works. If completed, it stops working, leaving no traces behind. The system does not need an uninstaller; simply deleting the directory is enough. Having installed Denver once, you can then simply rewrite it on other machines (on an arbitrary disk in an arbitrary directory). This will not cause any side effects. All configuration and setup for a specific machine occurs automatically. Very easy to install.
