The JDK is the Java Development Kit, the full-featured SDK for Java. It has everything the JRE has, but also the compiler (javac) and tools (like javadoc and jdb). It is capable of creating and compiling programs.
Sometimes, even if you are not planning to do any Java development on a computer, you still need the JDK installed. For example, if you are deploying a web application with JSP, you are technically just running Java programs inside the application server. Why would you need the JDK then? Because the application server will convert JSP into Java servlets and needs to use the JDK to compile the servlets.
The latest version of Java is Java 20 or JDK 20 released on March, 2023. However, many versions of Java are actively maintained for compatibility purposes. Java 8, Java 11 and Java 17 are the three long-term support versions recommended by Oracle. You can download the version you need below:
- Java SE 20 Download (latest)
- Java SE 19 Download
- Java SE 18 Download
- Java SE 17 Download (LTS, recommended)
- Java SE 16 Download
- Java SE 15 Download
- Java SE 11 Download (LTS, recommended)
- Java SE 9 Download
- Java SE 8 Download (LTS, recommended)
Java 8 is the last free software public update for commercial use, which explains why it remains popular. Oracle plans to maintain it until at least 2030. Also, you should know that some applications might refer to Java 8 as version 1.8.0.
The new Oracle Technology Network License Agreement for Oracle Java SE is substantially different from prior Oracle JDK licenses. The new license permits certain uses, such as personal use and development use, at no cost – but other uses authorized under prior Oracle JDK licenses may no longer be available.
What is Java?
Java is a programming language and software platform. Examples of applications that use Java are numerous and widespread but include web browsers, office applications and even mainstream games like Minecraft are based on Java.
What is Java JRE?
The Java Runtime Environment or JRE contains everything required to run Java applications on your system. The JRE software package includes the Java Virtual Machine (JVM), the Java Class Library, the Java command, and other infrastructure. JRE cannot be used to create new programs.
What is Java JDK?
The Java Development Kit (JDK) is the full-featured software development kit for Java developers. It has everything the JRE has, but adds the compiler (javac) and tools (like javadoc and jdb). The JDK allows you to create and compile Java programs.
Do I need Java JRE or Java JDK?
Unless you are a software developer, you only need to install Java JRE in your system to run Java programs. On the other hand, if you are planning to do some Java programming, you need to install the JDK instead.
Sometimes, even if you are not planning to do any Java programming, you still need the JDK installed. For example, if you are deploying a web application with JSP, you are technically just running Java programs inside the application server. Why would you need the JDK then? Because the application server will convert JSP into Java servlets and needs to use the JDK to compile the servlets.
Is Java free to use?
Yes, Java is free to use under the jdk.java.net license. This means anyone can download it for personal or development use at no cost. Oracle does charge for long term support, but this is optional.
What popular apps use Java?
As the fifth most popular programming language in the world, there is a long list of popular apps that rely on Java. From games like Minecraft and RuneScape, services like Netflix, Spotify and Uber, and applications like Opera Mini have all been created using Java.

Важная информация
Для TLauncher нужна именно Java 8! В некоторых Linux системах работает и с Java 11.
Рекомендованная версия Джава для Minecraft (1.16.5 и ниже) на Windows: Java 8 Update 51 (приоритет) или Java 8 Update 45.
Рекомендованная версия Java для Майнкрафт (1.16.5 и ниже) на MacOS/Linux: Java 8 Update Последний.
Рекомендованная версия Джава для Minecraft (1.17 и 1.17.1) на Windows: Java 16 (используемая разработчиками игры).
Рекомендованная версия Java для Майнкрафт (1.17 и 1.17.1) на MacOS/Linux: Java 16 (используемая разработчиками игры).
Рекомендованная версия Джава для Minecraft (1.18 и выше) на Windows: Java 17 (используемая разработчиками игры).
Рекомендованная версия Java для Майнкрафт (1.18 и выше) на MacOS/Linux: Java 17 (используемая разработчиками игры).
ВНИМАНИЕ: TLauncher автоматически* использует нужную версию Java рекомендованную разработчиками игры: для версии игры 1.18 — Java 17, для игры 1.17 — Java 1.16, для игры 1.16.5 и ниже — Java 8 Update 51. Поэтому, не нужно вручную устанавливать Java 16 или 17! Если происходит ошибка запуска связанная с Java, то проверьте в настройках лаунчера (Иконка «Шестеренки» -> «Настройки»), что стоит «Выбор Java» на «По умолчанию«. Если стоит другая версия, лаунчер будет пытаться запустить каждую версию от нее и может быть ошибка! Меняйте это, если понимаете для чего.
* Нужно использовать актуальную версию TLauncher 2.84 и выше.

С помощью нее вы можете играть в игры, закачивать фото, иметь возможность онлайн-общения, дистанционного обучения, банковского обслуживания, подключения к интерактивным картам. Если Java не установлена в системе, многие сайты и веб-приложения могут просто не работать.
Язык программирования Java был разработан в 1995 году компанией Sun Microsystems.
Сегодня множество Интернет-приложений, веб-ресурсов не могут функционировать при отсутствии этого языка на компьютере. Количество таких сайтов и приложений неуклонно возрастает.
После скачивания программы пользователи получают JRE (Runtime Environment), состоящее из JVM (Virtual Machine) и вспомогательных библиотек Джава-платформы.
JRE позволяет запускать в современных браузерах апплеты, которые написаны на языке программирования Java. Подключаемый модуль это не автономная утилита, поэтому не может быть загружена отдельно.
Программа по умолчанию сообщит вам об имеющихся для нее обновлениях. Советуем немедленно загрузить их для сохранения безопасности ПК. Последняя версия Java Runtime Environment содержит все необходимые улучшения, повышающие производительность и стабильность системы.
Плюсы
Работоспособность множества веб-сайтов и программ зависит от Java. Поэтому приложение желательно установить на компьютер и контролировать его запуск в браузерах.
Минусы
Некоторые эксперты по компьютерной безопасности предупреждают о возможной уязвимости ПО и ее компонентов.
В целом, это быстрое и надежное приложение, которое используется сейчас повсюду — в ПК, игровых консолях, сотовых телефонах. Установленная версия работает незаметно в вашей системе, не тормозит ее и не доставит вам беспокойств.
