can someone help me complete this program.. its giving me a head ache...

Code tags:

[code=JAVA] // paste code here

[/code]

Code looks terrible without them.

This looks like a cut and paste of the assignment specification that someone gave you. What seems to be the problem?

i dont know what to use. I need to be able to create a table. where i can input my scores and the weight or percentage of one quiz. Then the out put should be the final grade or the average score

The code gives you a guide. Start filling it in. Call the constructor from main. Do lines 12 - 35 and set up the GUI and display it. That gives you a start and requires no Action Listeners and no calculations and no need for any input. Ignore line 15 for now. You need to do them anyway, so might as well start there. It's just building the GUI.

import java.awt.event.ActionListener;
import javax.swing.JFrame;

//This Java Program determines the weighted average
//of four test scores.

//import statements for the needed packages

public class Assign1 extends JFrame
{

//declare JLabel variables as reference to label components
//declare JTextField variables as reference to input/output text boxes
//declare JButton variables as reference to command buttons
//declare button handlers to handle click events of command buttons
//declare constants to hold the size of your windows

public Assign1()
{
// Create eight labels

//Create four textfields

//create Calculate Button

//Create Exit Button

//Set the title of the window

//Get the container

//Set the layout
//Place the components in the pane

//set the size of the window and display it
}

// class which defines the action when the Calculate button is pressed
private class CalculateButtonHandler implements ActionListener
{
public void actionPerformed(ActionEvent e)
{
//place your code here
}
}

// class which defines the action when the Exit button is pressed
private class ExitButtonHandler implements ActionListener
{
public void actionPerformed(ActionEvent e)
{
//place your code here
}
}

// main method which constructs this particular class
public static void main(String[] args)
{
//place your code here
}
}

Does anyone have any ideas how to limit or require the sum of the weights to equal 1.00? My program compiles, runs, and functions, but I can't figure out how to regulate the weight column so that it must add up to 1.00.
This is what I have

Sorry I am new to this site. I am still learning how all of this works, thanks for the info though. I will do that next time.
