hello all

i have just started to work with imagej and am trying to develop plugins.
from the tutorials for writing plug ins i get to know that i can also get
the plugins integrated into the imagej GUI by having an underscore with the
class name. i also see the same with the example plugins Filer Plugin and
Plugin Frame. but when i try the same with a java hello world program i am
not able to see it under the plugin submenu. of course its the example code
which is as follows and saved as Hello_World.java in the plugin folder

import ij.*;
import ij.process.*;
import ij.gui.*;
import java.awt.*;
import ij.plugin.*;

public class Hello_World implements PlugIn {

    public void run(String arg) {
        IJ.showMessage("My_Plugin","Hello world!");
    }

}


could someone help me with my simple doubt. i am sure its the most basic
doubt

thank you for the help
