Загрузить пакет JDK (Java Development Kit)
Установить JDK (Java Development Kit)
Добавить системную переменную JAVA_HOME

В этом уроке описано, как установить JDK на Windows. Для установки JDK на Linux воспользуйтесь этой инструкцией.

Загрузка пакета JDK (Java Development Kit)

Заходим на сайт компании Oracle и скачать файл установки отсюда

На странице загрузки выберите нужную версию Java (для Android Studio требуется версия 7 или 8 ) и нажмите кнопку загрузки JDK:

В таблице отмечаем согласие с условиями, выбрав пункт Accept License Agreement и загрузите пакет для вашей ОС:

Например, для Windows следует выбрать файл jdk-XuXXX-windows-x64.exe для 64-разрядной (Windows x64) или jdk-XuXXX-windows-i586.exe для 32-разрядной (Windows x86). Разрядность системы, например, в Windows 7 можно узнать так: жмем «Пуск», правой кнопкой мыши «Компьютер», выбираем «Свойства».

Установка пакета JDK (Java Development Kit)

Для установки Java необходимо иметь права администратора (перезагрузить компьютер, если необходимо войти с другой учетной записью). Проверяем, установлена ли Java на компьютере (Пункт «Установка и удаление программ в панели управления Windows») и, если да, то удаляем ее. Запускаем установщик jdk-XuXX-windows-x64.exe. После запуска установщика на экране будут отображаться окна установки, в них лучше ничего не менять, продолжать установку нажатием кнопки Next. В последнем окне нажимаем Close.

Добавляем системную переменную JAVA_HOME

Чтобы было можно компилировать и выполнять программы осталось прописать пути к компилятору Java в переменных среды Windows и перегрузить компьютер. Для этого запускаем Панель управления Windows и выбираем пункт «Система», а в появившемся окне слева — пункт «Дополнительные параметры системы». Откроется окно «Свойства системы», в котором нажимаем кнопку «Переменные среды».

В появившемся окне вам надо создать системную переменную – “JAVA_HOME”. Для этого нажимаем кнопку “Создать”. В поле «Имя переменной» пишем “JAVA_HOME”, а в «Значение переменной» необходимо добавить путь к установленному JDK, а именно путь к его подкаталогу bin, где находится файл компилятора. Если вы ничего не меняли при установке JDK, то путь будет таким: «C:\Program Files\Java\jdkНомерВерсии». Ниже на картинках приведен пример для версии Java 7.

Теперь нужно отредактировать переменную “Path”. Надо ее найти в списке и нажать кнопку “Изменить”. Будьте внимательны – здесь надо в поле «Значение переменной» просто дописать наш путь C:\Program Files\Java\jdk1.7.0_79\bin\ (для текущей версии java 8, соответственно, \jdk1.8.0_121\bin\ ) предварительно поставив “; ” в конец уже существующего значения, ничего не удаляя ! Пример показан на рисунке.

После внесения этих изменений, чтобы они вступили в силу, компьютер необходимо перегрузить.

После этого можно проверить корректность установки JDK. Для этого в Windows нажмите «Пуск» и введите команду cmd в поле «Найти программы и файлы», или вызовите окно ввода комбинацией клавиш Windows+R и введите cmd.

В открывшейся консоли наберите java -version и нажмите Enter. Если вы видите версию java, а не сообщение об ошибке, все в порядке.

Java Development Kit is the official development kit for the Java programming language. Java Development Kit contains the software and tools that you need to compile, debug, and run applets and applications written using the Java programming language.

JDK has a collection of programming tools, including javac, jar, and the archiver, which packages related class libraries into a single JAR file. This tool also helps manage JAR files, javadoc - the documentation generator, which automatically generates documentation from source code comments, jdb - the debugger, jps - the process status tool, which displays process information for current Java processes, javap - the class file disassembler, and other components are also included.

Key Contents include:

Development Tools (In the bin/ subdirectory) Tools and utilities that will help you develop, execute, debug, and document programs written in the JavaTM programming language.
Runtime Environment (In the jre/ subdirectory) An implementation of the Java Runtime Environment (JRE) for use by the JDK. The JRE includes a Java Virtual Machine (JVM), class libraries, and other files that support the execution of programs written in the Java programming language.
Additional Libraries (In the lib/ subdirectory) Additional class libraries and support files required by the development tools.
Demo Applets and Applications (In the demo/ subdirectory) Examples, with source code, of programming for the Javaplatform. These include examples that use Swing and other Java Foundation Classes, and the Java Platform Debugger Architecture.
Sample Code (In the sample subdirectory) Samples, with source code, of programming for certain Java API"s.
C header Files (In the include/ subdirectory) Header files that support native-code programming using the Java Native Interface, the JVM Tool Interface, and other functionality of the Java platform.
Source Code (In src.zip) Java programming language source files for all classes that make up the Java core API (that is, sources files for the java.*, javax.* and some org.* packages, but not for com.sun.* packages). This source code is provided for informational purposes only, to help developers learn and use the Java programming language. These files do not include platform-specific implementation code and cannot be used to rebuild the class libraries. To extract these file, use any common zip utility. Or, you may use the Jar utility in the JDK"s bin/ directory: jar xvf src.zip.

The JDK also comes with a complete Java Runtime Environment. This consists of a Java Virtual Machine and all of the class libraries present in the production environment, as well as additional libraries, internationalization libraries and the IDL libraries.
