4 random positions in the world

Question

Ok so this is the code that i have writen so far:
Random aRandom;
aRandom.nextBoolean();
aRandom.nextInt(4);
System.out.println(aRandom);
if (aRandom == 0)
chaser.moveTo(160,120);
if (aRandom == 1)
chaser.moveTo(160,360);
if (aRandom == 2)
chaser.moveTo(480,120);
if (aRandom == 3)
chaser.moveTo(480,360);
this is what the outcome is supposed to be :
Chaser is created at one of 4 positions in the
world: (160, 120), (160, 360), (480, 120), or (480, 360). You must use a random decision to choose
which of the four locations Chaser should start at.
im really new to this does anyone khow what im doing wrong?
below is the starter code that i have just in case anyo0ne wants to take a look at it!
// Fall 2008 Comp 110 Barnes Project 2
// Put descriptive comments about what your program does and how it does it
import java.util.Random; // used for making probabistic decision
// You must use the methods and the arguemtns in this starter file.
public class TurtleTag {
// class instance variables are declared outside of any class method
// and are accessible from anywhere within the class.
Random aRandom; // object that returns (gets) random values
Turtle chaser, evader; // Turtle "objects" of our game
int delayInterval = 750; // time delay between steps to see the chase
int chaserStep = 5, evaderStep = 8; // distance of turtle's step
// Constructor method -- makes a TurtleTag object.
public TurtleTag(World aWorld, int gameSteps) {
int chaseX = 160, chaseY = 120; // starting location for chaser turtle
// create a new Random
// create a new evader Turtle and give it a name
// set the value of steps here
evader = new Turtle(aWorld);
evader.setName("evator");
// determine where chaser turtle will start
Random aRandom;
aRandom.nextBoolean();
aRandom.nextInt(4);
System.out.println(aRandom);
if (aRandom == 0)
chaser.moveTo(160,120);
if (aRandom == 1)
chaser.moveTo(160,360);
if (aRandom == 2)
chaser.moveTo(480,120);
if (aRandom == 3)
chaser.moveTo(480,360);
// create chaser turtle and give it a name.
chaser = new Turtle(chaseX, chaseY, aWorld);
chaser.setName("chaser");
System.out.println("TurtleTag written by " + "Antonio Arana");
System.out.println(chaser);
System.out.println(evader);
System.out.println("Chaser is after Evader.");
// call the play() method to have chaser chase evader
play(gameSteps);
System.out.println("TurtleTag is done");
} // end of TurtleTag(...)
// Wait delayInterval milliseconds between steps.
// Do not change this method or its call in play.
// This method is needed for moving Turtles.
private void delay() {
try { Thread.sleep(delayInterval); }
catch (InterruptedException ie) {
System.out.println("Error in delay() " + ie.toString());}
} // end of delay()
// Write the definition (body) for this method.
public void chaserMove() {
// Put your code here
// Write the definition (body) for this method.
public void evaderMove(boolean decision) {
// Put your code here
// Uncomment the declaration of this method.
// Write the definition (body) for this method.
// public int distanceBetween(Turtle chase, Turtle evade) {
// Put your code here
// Play the game of tag between two turtles for steps moves.
// Complete the definition (body) for this method.
public void play(int steps) {
// you may have to define and possibly initialize
// some local variables here
// get positions of chaser and evader turtles
// while not tagged and moves is less than steps) do
// moves++;
// chaserMove();
// distance = distanceBetween("what arguments go here?");
// if ( distance <= 10) {

Answer 1

should i use the aRandom.nextInt(max) intead i am so confused right now i wish i could just give up but i have to do this even if it takes me all week!
I am really new to this and the teacher that i have never answer our questions. the book that we read for this class desent even teach us how to do randoms sorry that im writing this im just really sick of this because i have been trying to figure this out from yesterday to today and this is just the begining.
Bye the way i really apreciate your help even though i think that i am geting more confused.
so what i have so far is totaly wrong right?
