Import Function Problem.

Question

I made a new ICT with a name of "DrawSquare" and imported the code my teacher gave me.
* DrawSquare This class will create a piece of paper and a pencil,
* place the pencil on the paper and then draw a square 100 units on
* each side.
* @author G. Peck
* @created March 23, 2002
import apcslib.*;
public class DrawSquare
* The main program for the DrawSquare class
* @param args The command line arguments (not used)
public static void main(String[] args)
DrawingTool pencil;
SketchPad paper;
paper = new SketchPad(300, 300);
pencil = new DrawingTool(paper);
// draw the square
pencil.forward(100);
pencil.turnLeft(90);
pencil.forward(100);
pencil.turnLeft(90);
pencil.forward(100);
pencil.turnLeft(90);
pencil.forward(100);

However when I try to compile this file it gives me this error.
Configuration: j2sdk1.4.2 <Default>
C:\java\basic\square\DrawSquare\DrawSquare.java:52: 'class' or 'interface' expected
import apcslib.*;

1 error

Answer 1

Ok I removed the second half of the file and tried compiling. Now I get 5 errors now.
