VM arguments

Have you ever wondered where that value came from in a Java program? One place to look for is the VM arguments. They are set in the system and not when you are writing your code.

A code like this will give you some good understanding of VM arguments.

import java.lang.management.ManagementFactory;

import java.lang.management.RuntimeMXBean;

RuntimeMXBean RuntimemxBean = ManagementFactory.getRuntimeMXBean();

List arguments = RuntimemxBean.getInputArguments();

Iterator iterator = arguments.iterator();

System.out.println(“VM arguments”);

int i=0;

for(;iterator.hasNext();)

{

System.out.println(iterator.next().toString());

}

System.out.println(“Number of VM arguments :”+i);
