import Media.*; public class test1{ private TurtleDisplayer display; private Turtle yertle; public test1(){ TurtleDisplayer display = new TurtleDisplayer(); Turtle yertle = new Turtle(); display.placeTurtle(yertle); drawLine();
import Media.*;
public class test1{
private TurtleDisplayer display;
private Turtle yertle;
public test1(){
TurtleDisplayer display = new TurtleDisplayer();
Turtle yertle = new Turtle();
display.placeTurtle(yertle);
drawLine();
display.close();
}
private drawLine(){
yertle.moveTo(60,60);
}
public static void main(String[] args){new test1();}
}
This program generates a null pointer exception at yertle.moveTo(60,60); Why is this happening? Whatmust I do to fix it?
