Thread: Find out how long it takes to do something

Right, ever wanted to know how many ms it takes a player to login, or how long it takes your server to do something so then you can see if anything you do creates a speed increase or decrease? If you follow this tutorial you can...

First create a class called ProcessContainer, put this in:

Code:

/*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */

package com.nathanroys.irc.processing;

/**
 *
 * @author Nathan
 */
public class ProcessContainer {

    public static ProcessContainer instance = new ProcessContainer();
    public static long processTime;

    public static ProcessContainer getInstance() {
        return instance;
    }

    public long processTime(Processer p) {
        long startTime = System.currentTimeMillis();
        p.process();
        processTime = System.currentTimeMillis() - startTime;
        return processTime;
    }
}

Then create a new class called Processer, put this in it~:

Code:

/*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */

package com.nathanroys.irc.processing;

/**
 *
 * @author Nathan
 */
public interface Processer {

    public void process();
}

Now, to see how long it has taken to do something you would do the following:

Code:

        System.out.println("Completed in "+
                        ProcessContainer.getInstance().processTime(new Processer() {

            @Override
            public void process() {
                  sendMessage("Hey");
            }
        })+"ms"
        );

Or just:

Code:

        ProcessContainer.getInstance().processTime(new Processer() {

            @Override
            public void process() {
                   sendMessage("Hey dude");
            }
        });
           System.out.println("Took " + ProcessContainer.processTime + "ms taken to execute!");

Hope this helps a few people..
