1. To input any two numbers and print their sum, and product by leaving two lines in between
2. To accept values of two numbers and interchange their values.​

Answer 1

Answer:

Program 1

import java.util.*;

public class Number

{

public static void main(String args[])

{

Scanner in=new Scanner(System.in);

int a,b,sum, product;

System.out.println("Enter the 2 numbers");

a=in.nextInt();

b=in.nextInt();

sum=a+b;

product=a*b;

System.out.println("The sum of the numbers="+sum);

System.out.println();

System.out.println();

System.out.println("The product of the numbers="+product);

}

}

Program 2

import java.util.*;

public class Num

{

public static void main(String args[])

{

Scanner in=new Scanner(System.in);

int a,b;

System.out.println("Enter the value of a");

a=in.nextInt();

System.out.println("Enter the value of b");

b=in.nextInt();

System.out.println("a="+b);

System.out.println("b="+a);

}

}
