Get Java Home Directory
Use the System.getProperty() method in Java to get the Java Home Directory.
It’s syntax is −
String getProperty(String key)
Above, the key is the name of the system property. Since, we want the Java Home Directory name, therefore we will add the key as −
java.home
The following is an example −
Example
public class Demo {
public static void main(String[] args) {
System.out.println("Get Java Home Directory = " + System.getProperty("java.home"));
System.out.print("Java Specification Version: ");
System.out.println(System.getProperty("java.specification.version"));
System.out.print("java Runtime Environment (JRE) version: ");
System.out.println(System.getProperty("java.version"));
}
}Output
Get Java Home Directory = /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.141-1.b16.fc26.x86_64/jre Java Specification Version: 1.8 java Runtime Environment (JRE) version: 1.8.0_141
