Thread: swapping integers OOP

so my class has ust begun oop. We are asked to make a class called Swapper with two integer instances variables x, y and a constructor with two parameters that inirtialize the parameters. Also three methods a getX that returns x a getY that returns y and a void swap that swaps the values of x and y then create a SwapperDemo class that tests all methods. Im stuck and having problems grasping how to send between two filrs and all that.

here is what I got:

public class Swapper {
int X;
int Y;
 
 
public Swapper(int i, int j) {
	// TODO Auto-generated constructor stub
}
int getX(){
return X;
}
int getY(){
	return Y;
}
void swap(){
    int temp;
    temp = this.X;
    this.X = this.Y;
    this.Y = this.X;
}
}

 
class DemoSwap {
public static void main (String[] args){
	Swapper x = new Swapper(9, 8);
	Swapper y = new Swapper(7, 0);
 
	System.out.println(x.X);
}
}

im obviously way off but not sure how this all works.

--- Update ---

so i think this works does this look right?

 
public class Swapper {
int X;
int Y;
 
 
public Swapper(int i, int j) {
	X=i;
	Y=j;
	// TODO Auto-generated constructor stub
}
int getX(){
 
return X;
}
int getY(){
	return Y;
}
void swap(){
    int temp;
    temp = this.X;
    this.X = this.Y;
    this.Y = this.X;
}
}

 
class DemoSwap {
public static void main (String[] args){
	Swapper tempZ = new Swapper(9,5);
 
 
	System.out.println("The value of X is "+tempZ.X);
	System.out.println("The value of Y is "+tempZ.Y);
	System.out.println();
	System.out.println("When the values are swapped ");
	System.out.println();
	System.out.println("The value of X is "+ tempZ.getY());
	System.out.println("The value of Y is "+ tempZ.getX());
}
}

Hi,
In swap function
temp = this.X;
this.X = this.Y;
this.Y = temp;

and in the demoswap function the last two lines should display The value of X as tempZ.getX() and the value of Y as tempZ.getY()

Hope this solves your problem.
