Lab 3: Building Applets - Graphical representation

Adding draw(Graphics) method in Msc Class

We want to represent an Msc graphically by drawing all the registered Rbs (which is stored in the rbss[] array) into the Graphics context. Since we have defined the draw(Graphics) method of Rbs, we can just call them for each element stored in the rbss[] array.

for (int i=0; i<numOfRbs; i++) 
{
   rbss[i].draw(g);
}

The complete implementation in Java is shown below.

import java.util.*;
import java.awt.Graphics;
import java.awt.Color;
public class Msc
{

     // . . . all other code of the original Msc Class
       
     public void draw(Graphics g)
     {
          for (int i=0; i<numOfRbs; i++) 
          {
             rbss[i].draw(g);
          } 
     } 
}
