To get Java Home directory we can obtain it from system properties using the java.home
key.
package org.kodejava.example.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 = /Library/Java/JavaVirtualMachines/jdk1.8.0_121.jdk/Contents/Home/jre
