java: Display JDK, JRE and HotSpot versions.
$ java -version
try on your machine
The command "java -version" is used to display the version information of the Java Runtime Environment (JRE) installed on your computer.
When you run this command in the command line or terminal, it will execute the "java" executable with the "-version" option. This causes Java to output information about the version of the JRE that is installed.
The output typically includes the version number of the JRE, the Java Virtual Machine (JVM), and the Java HotSpot VM. It may also provide additional details such as the build and release information.
This command is often used to verify if Java is installed correctly and to check the compatibility of Java applications or programs with the installed version of Java.
