Как проверить версию JDK, установленную на вашем компьютере
Вот краткое руководство, показывающее использование команды « java -version » для проверки текущей версии JDK, установленной на вашем компьютере.
1. Откройте командную строку в Wndows или терминал в * nix.
2. Введите « Java-версия ».
C:>java -version java version "1.6.0_18" Java(TM) SE Runtime Environment (build 1.6.0_18-b07) Java HotSpot(TM) Client VM (build 16.0-b13, mixed mode, sharing)
В этом случае JDK « 1.6.0_18 » устанавливается на компьютер.

Если JRE, то java -version
Если JDK, то должен быть компилятор как минимум javac -version, но может не отработать если переменные среды не настроены
