How do I get Java Home directory?

To get Java Home directory we can obtain it from system properties using the java.home key.

package org.kodejava.lang;

public class JavaHomeDirectory {
    public static void main(String[] args) {
        String javaHome = System.getProperty("java.home");
        System.out.println("JAVA HOME = " + javaHome);

On my computer this code give me the following output:

JAVA HOME = C:\Program Files\Java\jdk-17
