Write a program to swap two numbers using a temporary variable.
public class swap1
{
public static void main()
{
int temp;
int a=3;
int b=9;
temp=a;
a=b;
b=temp;
System.out.println("After swapping, a="+a);
System.out.println("After swapping, b="+b);
}
After swapping,a will be=9 After swapping,b will be=3 |
Write a program to swap two numbers without using a temporary variable.
public class swap2
{
public static void main()
{
int a=3;
int b=9;
a=a+b;
b=a-b;
a=a-b;
System.out.println("After swapping, a="+a);
System.out.println("After swapping, b="+b);
}
After swapping,a will be=9 After swapping,b will be=3 |
rite a program
