public class Swap {
String jas = "jas";
String jaswinder = "jaswinder";

public String getJas(){
return jas;
}
public void setJas(String jas){
this.jas = jas;
}

public void setJaswinder(String jaswinder){

use this

package com.company;

public class SwapClass{

int a = 1;
int b = 2;

public static void main (String []args) {
SwapClass swapInstance = new SwapClass();
swapInstance.swapInstanceMethodNotWorks();
swapInstance.swapInstanceMethodThisWorks();
}

public void swapInstanceMethodNotWorks () {
System.out.println("Before a is " + a);
System.out.println("Before b is " + b);
this.swapNoThisNoWork(a,b);
System.out.println("After a is still " + a);
System.out.println("After b is still " + b);
}

public void swapInstanceMethodThisWorks () {
System.out.println("Before a is " + a);
System.out.println("Before b is " + b);
this.swapWithThisWorks(a,b);
System.out.println("After a is now " + a);
System.out.println("After b is now " + b);
}

public void swapNoThisNoWork (int a , int b) {
int localTempHolderVar;
localTempHolderVar = a;
a = b;
b = localTempHolderVar;
}

public void swapWithThisWorks (int a , int b) {
int localTempHolderVar;
localTempHolderVar = a;
this.a = b;
this.b = localTempHolderVar;
}

}


Before a is 1
Before b is 2
After a is still 1
After b is still 2
Before a is 1
Before b is 2
After a is now 2
After b is now 1
