Download java for all operating systems. Installing java on windows

Java (Java)- runtime to open applications written in the language Java programming. Java for computer in Russian and completely free. It includes a package for creating applications and virtual machine to launch them. The main plus of Java for Windows 7, 8, 10 is cross-platform. This means that a client that is released, for example, on Windows, will also run under Linux.
Many programs, toys and even some web pages are written in Java. For example, very often people search on the Internet Java for Minecraft, because the game works on this platform. You may think that Java and JavaScript are the same thing. JavaScript is widely used on the Internet, but you do not need to install the Java Runtime Environment to work with this language, it is simply built into the browser right away. On the one hand, the client interface is so easy that even a beginner can handle it, but, on the other hand, to create an application on your own, it’s better to use additional information. latest version Java / Java free download in Russian, you can follow a direct link from the official website to our website.

Java Program Features for Windows 7, 8, 10:

• Implementation of memory management tools;
• Uncomplicated interface;
• Cross-platform client;
• Multilingual;
• Minimum system requirements;
• Allows you to create applications;
• Allows adding http requests in Java applications;
• Work simultaneously with several applications;
• Availability of templates;
• The implementation in the application of almost all the possibilities for creating personal software.

The Java programming language is rapidly gaining popularity due to its simplicity and functionality. Many mobile and computer applications are written in this language. It is worth noting that applications for Android devices are written specifically in Java.

Download Java is available on the official website completely is free. However, there may be a question with the version of the program. First of all, you have to choose between 32 bit and 64 bit version. If the computer allows, then of course it’s better to stop at 64, she doesn’t have such strict restrictions on memory usage.

Then it is worth deciding - to install Java Development Kit (JDK) or Java Runtime Environment (JRE). Everything is extremely simple and clear, if you translate the abbreviation. JDK is a development kit. It is used to create programs in that language.

JRE only allows you to run applications. By the way, it is included in the JDK.

Package installation

Installation is no different from other applications. For example, let's take the package installation JDK.

Environment variable settings

Unfortunately, the installer does not make all the necessary settings, so variable environment must be configured manually.

First of all, it will be necessary to define variablejava_ home, which contains the path to the folder where Java is installed. This variable use many programs to watch location Java.

Then you need to variable path prescribe the location %JAVA_HOME%\bin. It is used by the operating system to see a list of folders where the executable file can be found. She also used to run Java from the console.

To get started, you need to go to computer properties. You can do this in any convenient way, for example, call the context menu of My Computer and click Properties, or press combination win+Pause.

Now open Additional system settings, and in the next window go to the tab Additionally. Here we go to Environment Variables(button below).

If the system variables are already entered Java_ home, then you need it edit. If it doesn't exist, then we create a new one. Here we will need set path to installed Java. For example c:\Program Files\Java\jdk\ or any other where the installation was made.

Now we need to change the variable Path. Here we specify the path to the folder where the executable files are located, for example %JAVA_HOME%\bin.

Now close all windows by pressing OK, saving the changes.

It is worth noting that for the JDK, the installation folder contains numbers– package version. Therefore, every time you update, you need to change the directory in JAVA_ HOME otherwise the program simply won't start.

Delete extra files

Now left clean up system from junk files. To do this, we launch command line (cmd). Then we use the command where java. The console should display the Java installation path. If the directory not found- means the path variable is incorrectly filled. However happens that the system finds multiple executable files.

This is due to the fact that installer tries incorrectly tune Environment Variables. Those. trying to install them in a folder system32 .

This is bad, because system directory while gets clogged and you can expect the program to work incorrectly. In this case, we go to the path indicated in the console and delete all files: java.exe, javaws.exe and javaw.exe. If some of these files are not found, then delete only those located in the folder.

Java Runtime Environment (JRE)- provides libraries, the Java virtual machine and other components for running applets and applications written in the Java programming language.

The Java JRE also contains technologies such as Java Plug-in and Java Web Start. Java Web Start - allows you to deploy standalone applications on the Internet. Java Plug-in - allows you to run applets in Internet browsers.

For an inexperienced user, another explanation will be more understandable. With the help of Java, webcams, printers, online games, accounting programs work on a computer. In other devices, Java manages the work: GPS-navigators, medical devices, parking machines and others.

This section contains the latest versions of the Java JRE package for installation on a personal computer or laptop. You need to select the version and bitness of your operating system, download the necessary files and install on your computer.

Java is an object-oriented programming language and an application software platform based on it. Java is an environment for running websites, online stores, forums, remote banking, virtual navigation maps, tutorials, online questionnaires and games, and other specialized web applications. It is often 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 of the Java project was that it allowed creating software that does not need in the compilation for each processor architecture and operating system.

Brief history of Java technology development and state of the art today

Java was developed by Sun Microsystems in 1991-1995, and later the technology was 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 free Java 64-bit or 32-bit for Windows 10, 8, 8.1 (desktop), 7 SP1, Vista SP2, Server 2008 R2 SP1 64-bit, Server 2012 and 2012 R2 64-bit to work with browsers Internet Explorer 9 and above, as well as Mozilla Firefox. Package software Java consists of four software components: the JRE, which is responsible for executing applets, the Java virtual machine that interprets the bytecode, base classes, and auxiliary libraries. Today, the Java Runtime Environment can deploy server-side Java applications, establish a browser connection with the Java platform. It is also worth paying attention to free programs with similar functionality: Microsoft . NET Framework, Microsoft Silverlight plugin, 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, safety and recommend latest version Java free download without registration from the official site. However, according to the reviews and comments of IT specialists, applications in Java take up more memory, have lower speed and responsiveness in contrast to their counterparts in C or C ++. But Java has a number of security and reliability advantages over languages ​​such as C, C++, Python, Fortran, Ruby, PHP, JavaScript and others.

Benefits of a platform-independent Java implementation

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

The advantages of Java include:

Reliable and safe 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,
- work with Java applets on the Internet,
- productive interaction with OpenGL and DirectX through Swing,
- GifWriter for working with animated gifs,
- full Unicode support.

Java security organization and updates

The impenetrable security system of Java is due to the fact that the execution of the application is controlled by the JVM completely. Abuse of authority, such as unauthorized use of data or sending of information, is terminated immediately. The JRE's high security level is maintained by maintaining a blacklist of certificates and JAR files. By default, only verified applications with a digital signature can be launched. Users of previous versions are advised to remove all obsolete software, download Java for Windows 7, 8, 8.1, 10 for free, as well as outdated Vista and server Windows 2008 and 2012, and install the latest version on their computer. Legacy Java may have vulnerabilities that are unsafe. Updates should be installed regularly to maintain a high level of security. Minor changes do not change indexing, but use the word Update (letter u), but they are no less important. No wonder if you need the latest Java download for Minecraft, Prince of Persia, Solitaire, Need for Speed, GTA, Zona Software, 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 high-quality video, the ability to access all settings and normal network gameplay.

How to properly install Java on a computer

To properly install Java on a PC, you first need to uninstall everything. To remove outdated software, use the standard option: Start - Control Panel - Uninstall a program. Next, you need to download Java for Windows for free from the site programmywindows.com, respectively, a 32-bit or 64-bit installation file, observing the bit depth of the main browser, close all browsers and running programs. When everything is ready, you can run 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 to make Java modules compatible with all browsers.
