Go4Expert - Problem reading objects

Here is my code:
Code:
import java.util.Random; //initialize random object 



  



public class Sprite { //claim the class 

private int xPos; //declare instance variable to be used throughout the class 

private int yPos; 

private Random positioner; //declare a random variable 

private Picture myPicture; //declare a picture variable 



  



public Sprite(Picture pict){ 



Random chooseValue = new Random(); //Create random object "ChooseValue" 

myPicture = pict; //Copy constructor 

positioner = chooseValue; //Object is randomized 

myPicture.getX(); //randomly obtain an x 

myPicture.getY(); //randomly obtain a y 



} 





  



public Sprite(Sprite other){ 

this.xPos = other.xPos; //Take value of xpos from other sprite 

this.yPos = other.yPos; //take value of ypos from other sprite 

this.positioner = new Random(); //positioner can't be copied 

this.Picture = new Picture(other.Picture); //copy constructor 



} 





  



public String toString(){ 

return "Sprite - location: " + xPos + "," + yPos + " picture: " + Picture; 



} 





  



public boolean equals(Sprite other){ 

if (this==other) //if this object is the same object 

return true;//its the same object 

else 

        return false;      //otherwise it's not

}







  



public int getX(){ //Obtain xPos 

int chooseValue = positioner.nextInt(76); //randomly choose a number from 0-75 

xPos = chooseValue; //assign xPos to that value. 

return xPos; //return xPos as that value 

} 





  



public int getY(){ //obtain yPos 

int chooseValue = positioner.nextInt(76); //randomly choose a number from 0-75 

yPos = chooseValue; //assign yPos to that value 

return yPos; //return yPos as that value 



} 





  



public Picture getPicture(){ //get picture 

return Picture; //return the picture 

} 





  



  



public void setNewPos(int newX, int newY){ //set new positions for values 

newX = xPos; //new xPos set 

newY = yPos; //new yPos set 

}}
