Why isn't this code working?

[pineappelle]

I have this code and when I press the run button only 0's appear instead of random numbers.

/**
 * @(#)chapter17random.java
 *
 * chapter17random Applet application
 *
 * @author
 * @version 1.00 2012/2/14
 */

import java.awt.*;
import java.applet.*;

public class chapter17random extends Applet {

	TextArea random;
	int grade[];
	int counter, random_number;

	public void init() {

		grade=new int[10];
		random=new TextArea(10,20);

		for (int counter=0;counter<0;counter=counter+1) {

			random_number=(int)(100*Math.random());
			grade[counter]=random_number;

		}

		random.append(""+grade[0]+"\n");
		random.append(""+grade[1]+"\n");
		random.append(""+grade[2]+"\n");
		random.append(""+grade[3]+"\n");
		random.append(""+grade[4]+"\n");
		random.append(""+grade[5]+"\n");
		random.append(""+grade[6]+"\n");
		random.append(""+grade[7]+"\n");
		random.append(""+grade[8]+"\n");
		random.append(""+grade[9]+"\n");

		add(random);

	}

}

you never set counter and there are problems with your for loop- I threw this in debugger and it worked fine...

int[] myGrade = new int[10];
int randomNum;

for(int i=0; i<myGrade.length; i++)
{
  randomNum = (int)(100*Math.random());
  // I inserted a break point in preceeding line and watched values come through fine
}
