1. Write a Java program that would input three numbers from the user and print sum, then the first number, then the 2^nd number followed by 3rd number. If user enters 10, 20, 30. then output should be 60, 10, 20, 30.

import java.util.Scanner;
public class Lab8q4{
  public static void main ( String [] args ){
    int [] number = new int [3];
    int c = 0, sum=0;
    Scanner input = new Scanner ( System.in );
    System.out.println("Enter 3 numbers");
    while(c<3){
      number  = input.nextInt();
      sum = sum + number ;
      ++c;
    }
    System.out.println("SUM : "+sum);
    c=0;
    while(c<3){
      System.out.println(number);
      ++c;
    }
  }
}

1. Write a Java program that would input ten numbers from the user and print the ten numbers in reverse order. If user enters 20, 10, 30, 15. Then output should be 15, 30, 10, 20.

import java.util.Scanner;
public class Lab8q5{
  public static void main ( String [] args ){
    int [] number = new int [3];
    int c = 0, sum=0;
    Scanner input = new Scanner ( System.in );
    System.out.println("Enter 3 numbers");
    while(c<3){
      number  = input.nextInt();
      sum = sum + number ;
      ++c;
    }
    c=2;
    while(c>=0){
      System.out.println(number);
      --c;
    }
  }
}
