Hi Karteek,

Check this code

public class SwappingClass 
{
 public static void swapmethod()
 {
     integer i=10, j=20;
     i=i+j;
     j=i-j;
     i=i-j;
     system.debug('check values of i = '+i);
     system.debug('check values of j = '+j);
 }
}

Thank You
Ajay Dubedi

Apex class:

public class Swapnumbers {
    public void Swapnumbersfunction(Integer x , Integer y){
        x=x+y;
        y=x-y;
        x=x-y;
        system.debug('n1 value' +x); 
        system.debug('n2 value' +y); 
        
    }
}

Annoymous window:
Swapnumbers sn=new Swapnumbers();
sn.Swapnumbersfunction(6,3);

Hi karteek,

public class SwapTwoNumber
{
 public static void swapNumber(integer x, integer y)
 {
System.debug("Before Swap number");
System.debug("x--> "+x);
System.debug(""Y--> "+y);
     integer z=0;
z=x;
x=y;
y=z;

System.debug("After Swap number");
System.debug("x--> "+x);
System.debug(""Y--> "+y);
     
 }
}
