Question

Using jGrasp and the Software Development Kit, write a program in response to the following prompt:

Design a GUI program to find the weighted average of four test scores. The four test scores and their respective weights are given in the following format:

testscore1 weight1
...

For example, the sample data is as follows:

75 0.20
95 0.35
85 0.15
65 0.30

The user is supposed to enter the data and press a Calculate button. The program must display the weighted average.

Remember to follow proper form and design in your response.

Explanation / Answer

import java.awt.Button;
import java.awt.Color;
import java.awt.Event;
import java.awt.Graphics;
import java.awt.Label;
import java.awt.TextField;
import java.applet.*;

public class WeightedAverage extends Applet
{
   TextField T1,T2,T3,T4,T5,T6,T7,T8;
   Button calculate=new Button("Calculate");
   Label result;
   double res;
public void init() {
T1 = new TextField(10);
T2 = new TextField(10);
T3 = new TextField(10);
T4 = new TextField(10);
T5= new TextField(10);
T6 = new TextField(10);
T7 = new TextField(10);
T8 = new TextField(10);
  
add(T1);
add(T2);
add(T3);
add(T4);
add(T5);
add(T6);
add(T7);
add(T8);
add(calculate);
T1.setText("0");
T2.setText("0");
T3.setText("0");
T4.setText("0");
T5.setText("0");
T6.setText("0");
T7.setText("0");
T8.setText("0");
}

public void paint(Graphics g) {
   g.drawString("Weighted Average is : "+res,10,80);
  
  
}

public boolean action(Event e, Object o){
repaint();

int w1, w2, w3, w4;
double avg=0.0;
if(e.target==calculate)
{

w1=Integer.parseInt(T2.getText());
w2=Integer.parseInt(T4.getText());
w3=Integer.parseInt(T6.getText());
w4=Integer.parseInt(T8.getText());

res=(w1+w2+w3+w4)/4;
}
return true;
}
}
