Java JDK
В настоящее время, Java является одним из самых используемых языков программирования в Интернете. Изначально, был разработан компанией Sun Microsystems, а теперь принадлежит компании Oracle, его популярность обусловлена тем, что он позволяет нам разрабатывать программные обеспечения, независимо от платформы, на которой они выполняются.
Разрабатывайте программы, написанные на языке Java.
И Java JDK 8 или Java Development Kit является средой разработки, предлагающей нам инструменты, необходимые для создания приложений, апплетов и других компонентов, используя язык программирования Java.
Как установить Java JDK на Windows
Установка этого средства разработки Java так же просто, как скачать перемещаемую выполняемую программу, которую мы предлагаем вам, и выбрать 32 или 64-разрядную версию в зависимости от вашей операционной системы Windows. С этого момента, просто следуйте инструкциям на экране, чтобы установить JDK на вашем компьютере, и через несколько минут вы сможете начать разработку, отладку и мониторинг приложений, написанных на языке Java.
Компоненты, включенные в Java SDK
Инструменты, включенные в этот пакет почти несчетное, но мы должны отметить, что он включает в себя полную среду исполнения Java (Java Runtime Environment — JRE) и виртуальную машину Java (JVM), а также много библиотек классов и других дополнительных библиотек. Среди своих компонентов, мы должны упомянуть:
- Appletviewer: для запуска и отладки Java-апплетов, не требуя веб-браузер.
- Javac: компилятор Java по преимуществу.
- Java: загрузчик программы Java и интерпретатор классов, сгенерированных Javac.
- Javadoc: генератор документации для всех классов Java.
- VisualVM: графический интерфейс с подробной информацией о приложениях Java, работающих на виртуальной машине.
- JConsole: графический инструмент для мониторинга виртуальной машины Java и его приложений, как локально, так и удаленно.
