1.	Write A Program To Swap Two Numbers Without Using Any Temp Variable?
Answer» Program to swap two numbers without using any TEMP variable is as below: public class swap{ public static VOID MAIN (String ARGS[]) { int x = 20; int y =30; System.out.println(“Numbers before swapping”); System.out.println(“ number x is “ + x); System.out.println(“number y is “ +y); // Swapping numbers x= x+y; y=x-y; x=x-y; System.out.println(“Numbers after swapping”); System.out.println(“ number x is “ + x); System.out.println(“number y is “ +y); } } Program to swap two numbers without using any temp variable is as below: public class swap{ public static void main (String args[]) { int x = 20; int y =30; System.out.println(“Numbers before swapping”); System.out.println(“ number x is “ + x); System.out.println(“number y is “ +y); // Swapping numbers x= x+y; y=x-y; x=x-y; System.out.println(“Numbers after swapping”); System.out.println(“ number x is “ + x); System.out.println(“number y is “ +y); } }

Answer»

Program to swap two numbers without using any TEMP variable is as below:

public class swap{

public static VOID MAIN (String ARGS[])

{

int x = 20;

int y =30;

System.out.println(“Numbers before swapping”);

System.out.println(“ number x is “ + x);

System.out.println(“number y is “ +y);

// Swapping numbers

x= x+y;

y=x-y;

x=x-y;

System.out.println(“Numbers after swapping”);

System.out.println(“ number x is “ + x);

System.out.println(“number y is “ +y);

}

Program to swap two numbers without using any temp variable is as below:

public class swap{

public static void main (String args[])

{

int x = 20;

int y =30;

System.out.println(“Numbers before swapping”);

System.out.println(“ number x is “ + x);

System.out.println(“number y is “ +y);

// Swapping numbers

x= x+y;

y=x-y;

x=x-y;

System.out.println(“Numbers after swapping”);

System.out.println(“ number x is “ + x);

System.out.println(“number y is “ +y);

}
