I have an assignment that wants me to implement the paint function for a Cube to a GUI but i don't know what to do for my Object Oriented Programming class. A snippet of the function would be really appreciated.

HERE'S THE CODE:

import java.awt.Color; import java.awt.Graphics;

public class Cube extends Square implements I_threeD{

public Cube(Color color, String name, int side) { super(color, name, side); }

@Override public float computeVolume() { return (this.mSide * this.mSide * this.mSide); } public void print(){ System.out.println("Cube ("+this.mName+") side : "+this.mSide+" and color : "+this.mColor.toString()); } public void paint(Graphics g) { final int step = 20; } }
