             Q1 : Write a program that input two number from user and display its sum using two variables
               import java.util.*;
               public class sum
            {
                   public static void main(String args[])
               {
                      Scanner p= new Scanner(System.in); //Take input from user
                       int num1,num2;
                   System.out.println("Enter number 1");
                    num1=p.nextInt();            //it is a way to take interger from user
                   System.out.println("Enter number 2");
                   num2=p.nextInt();
                    System.out.println("The sum of two number is "+(num1+num2));
                         }}
                     Output
                        Enter number 1 =9
                         Enter number 2 =8
                       The sum of two number is 17
              Q2:   Write a program that input two floating point numbers from user and display its sum using two variables
                    import java.util.*;
               public class sum
            {
                   public static void main(String args[])
               {
                      Scanner p= new Scanner(System.in); //Take input from user
                       double num1,num2;
                   System.out.println("Enter number 1");
                    num1=p.nextDouble();            //it is a way to take floating point number from user
                   System.out.println("Enter number 2");
                   num2=p.nextDouble();
                    System.out.println("The sum of two number is "+(num1+num2));
                         }}
                     Output
                        Enter number 1 =9.9
                         Enter number 2 =8.8
                       The sum of two number is 17.17
