Loading

  1. Go to the website and click the button Download .
  2. There are two types of installation packages.
    • Java on Linux platforms
      Installs the Java Runtime Environment (JRE) for Linux 32-bit using a zipped binary (.tar.gz) that can be installed by any user (not just root users) to any writable directory. However, only the root user can install Java in the system directory.
    • Java on RPM-based Linux platforms
      Installs the Java Runtime Environment (JRE) for 32-bit RPM-based Linux platforms such as Red Hat and SuSE using the RPM binary (.rpm) in the system directory. This setting can only be executed by the root user.
    Download the package that best suits your needs. The file can be loaded into any of the directories on the system.
  3. You must accept the terms of the license agreement before downloading the file.
  4. Download the file and check its size, to make sure the downloaded package is complete and not damaged. Before downloading the file, make a note of the file size listed on the download page of this website. After the download is finished, check that the downloaded file size matches the recorded file size.

Installation

Here are the instructions for installing Java 8 Update 73 (8u73). If you are installing a different version, specify the version number when entering commands in a terminal window. Example... For Java 8u79, replace 8u73 on 8u79... Note that in the previous example, the version number was sometimes preceded by the letter u, and sometimes by an underscore, such as jre1.8.0_73.

A note about accessing the root directory. For java installations in the system directory, for example / usr / local, you must be root with the necessary permissions. If you do not have root permissions, install Java to home directory or a subdirectory for which you have write permissions.

Java for Linux platforms
  1. Enter:
    cd directory_path_name
    cd / usr / java /
  2. Move the zipped binary .tar.gz to the current directory.
  3. Unpack tar archive and install Java
    tar zxvf jre-8u73-linux-i586.tar.gz

    Java files are installed in the jre1.8.0_73 directory created in the current directory.
    IN this example this is the /usr/java/jre1.8.0_73 directory.

  4. Delete the .tar.gz file
Java for RPM-based Linux platforms
  1. Switch to root user mode, by running the su command and specifying the root password.
  2. Remove more early versions Java packages.
    rpm -e package_name
  3. Change to the directory where you want to install. Enter:
    cd directory_path_name
    For example, to install the software in the / usr / java / directory, enter:
    cd / usr / java
  4. Install the package.
    rpm -ivh jre-8u73-linux-i586.rpm

    To update a package use
    rpm -Uvh jre-8u73-linux-i586.rpm

  5. Delete the .rpm fileif you need to save disk space.
  6. Log out of the root user console. No computer restart is required.

The installation is now complete. Go to section.

Startup and configuration

Firefox

When installing the Java platform, the Java plug-in file is part of the installation. To use Java in Firefox, you must manually create a symbolic link that links the plug-in file in the release to one of the locations defined by Firefox. For Firefox 21 and later, you need to create a symbolic link in your ~ / .mozilla / plugins home directory. Starting in Firefox 21, it is not supported to create symbolic links in the plugins subdirectory of the Firefox application directory.

To configure the Java plug-in, do the following:
  1. Close up firefox browserif it is executed.
  2. Uninstall any previous installations of the Java plug-in.
    Only one Java plug-in can be used at a time. If you need to use a different plug-in or plug-in version, remove the symbolic links to all other modules and create a new symbolic link to the new version.
  3. Create a symbolic link to the Java plugin in the Firefox plugins directory
    • Navigate to the Firefox plugins directory
      cd ~ / .mozilla / plugins
      Create a plugins directory if it doesn't exist.
    • Create a symbolic link.
      32-bit plug-in:
      In -s java installation directory /lib/i386/libnpjp2.so.
      64-bit plug-in:
      In -s java installation directory /lib/amd64/libnpjp2.so.
    Example
    • If Java is installed in this directory:
      / usr / java / java installation directory
    • Then, in a terminal window, navigate to the browser plugins directory:
      cd ~ / .mozilla / plugins /
    • Enter the following command to create a symbolic link to the Java Plug-in for Firefox:
      In -s / usr / java / java installation directory /lib/i386/libnpjp2.so.
  4. Launch Firefox browser or restart it if it was started.

    In Firefox enter about: plugins in the location bar to make sure the Java plugin is loaded. Alternatively, you can click the Tools menu to verify that the Java Console is available.

A Brief History of Java Technology Development and Current Status

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 ecosystem, Open JDK and JavaCommunityProcess. Today you can download Java 64-bit or 32-bit for free 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 older, and Mozilla Firefox... The Java software package consists of four software components: the JRE, which is responsible for executing applets, the Java virtual machine that interprets the bytecode, base classes, and supporting libraries. Today 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, plugin Microsoft Silverlight, Adobe Flash Player, Adobe Shockwave Player in the Platforms and Environments section.

Java versus popular programming languages

The main advantage of Java is platform independence. The developers promise speed, durability, security and recommend the latest version of Java to download for free without registration from the official site. However, according to reviews and comments of IT specialists, Java applications take up more memory, are slower and more responsive than their C or C ++ counterparts. But Java has a number of security and reliability advantages over languages \u200b\u200bsuch as C, C ++, Python, Fortran, Ruby, PHP, JavaScript and others.

Benefits of Java Platform Independent Implementation

The developers claim that any Java applet runs perfectly on different devicesrunning various operating systems. It is possible to download Java for free on almost any smart device and successfully install it, regardless of which 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 is complete independence. program code from OS and hardware. This feature allows Java applets to work at any compatible level virtual machine device.

The advantages of Java include:

Reliable and secure apps and games,
- work in multi-threaded mode,
- ideal functionality for network computing,
- powerful launch tools 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 gif files,
- full support for Unicode.

Java security organization and updates

Java's impenetrable security system is due to the fact that the execution of the application is completely controlled by the JVM. Exceeding the authority, for example unauthorized use of data or sending information, is immediately terminated. The JRE is highly secured by blacklisting certificates and JAR files. By default, only digitally signed verified applications can be launched. 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. Legacy Java can have vulnerabilities, which is unsafe. For supporting high level security updates should be installed regularly. 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 food supplement database, remote banking or other latest software. Moreover, free download Java for Minecraft and other Java games is simply necessary for high-quality video, the ability to access all the settings and normal network gameplay.

How to properly install Java on your computer

  • select the "Start" button;
  • select settings / control panel;
  • click on programs and components;
  • select from the list old version and click "Delete" on the panel.

The platform is deployed in the JRE environment, as well as by means of a virtual machine. Additional platforms, libraries and classes are also used. The JRE provides an applet runtime in the browsers available to it. Java has other features:

  • full support for applications with multiple worker threads;
  • there is full support for the service department on the Internet;
  • application of applets to customize programs;
  • the simultaneous use of several applications that use platform tools is supported;
  • tools for working with HTTP, receiving responses is done by separate classes.

Any software that has been written or created in the Java programming language requires this platform from the system. Due to the fact that this language is used in almost all areas (Internet, desktop programs), the system will often require the computer to have it.

  • easy installation on computer;
  • this software does not require any action from the user after installation;
  • can be installed on any OS.
  • does not work with all browsers;
  • insufficient speed of some applications with Java;
