Get Boot path from RuntimeMXBean in Java

RuntimeMXBean in the management interface for the runtime system of the Java virtual machine.

RuntimeMXBean runtimeMX = ManagementFactory.getRuntimeMXBean();

To get the boot path, use the getBootClassPath() method −

runtimeMX.getBootClassPath()

The following is an example −

Example

 Live Demo

import java.lang.management.ManagementFactory;
import java.lang.management.RuntimeMXBean;
import java.util.Date;
public class Demo {
   public static void main(String args[]) throws Exception {
      RuntimeMXBean runtimeMX = ManagementFactory.getRuntimeMXBean();
      System.out.println("Class path = "+runtimeMX.getClassPath());
      System.out.println("Boot Class path = "+runtimeMX.getBootClassPath());
   
   }
}

Output

Class path = /home/cg/root/GNUstep/Library/Libraries/Java:/usr/GNUstep/Local/Library/Libraries/Java:/usr/GNUstep/System/
