[Q#6646467][A#6646535] How to find time taken to run java program?

https://stackoverflow.com/q/6646467

For those out there that are familiar with java, I have an application that I've been working on and just realized that the program has to return a value in less than a minute, but don't know how to find or display the time taken to run the program. Any help with this would be greatly appreciated. Thanks

See

APIzation

long startTime = System.nanoTime();
//code
long endTime = System.nanoTime();
System.out.println("Took "+(endTime - startTime) + " ns");

package com.stackoverflow.api;

public class Human6646535 {

  public static long getRunningTime() {
    long startTime = System.nanoTime();
    //code
    //I am not sure about how to implement here
    long endTime = System.nanoTime();
    return (endTime - startTime);
  }
}
