Question

Write a Java program to do the following USING ARRAYS

1) input 15 integers (input validation, all numbers must be between 0 and 100)

2) find the largest number.

3) Find the Smallest Number

4) Find the Sum of all numbers in the Array

Display:

Largest Number

Smallest Number

Sum of all numbers

the original Array

Answer 1

import java.util.*;

public class Main
{
   public static void main(String[] args) {
       Scanner s = new Scanner(System.in);
       int a[] = new int[15];
       int flag = 0, sum = 0, max = -1, min = 101;
       while(true)
       {
       sum = 0;
       max = -1;
       min = 101;
       System.out.print("Enter the 15 elements : ");
       for(int i = 0; i < 15; i++)
       {
       int n = s.nextInt(); // read the elemetns
       if(n > 0 && n < 100)
       {
       a[i] = n;
       sum = sum + n; // summation of numbers
       if(n < min)
       {
       min = n; // find minimum
       }
       if(n > max)
       {
       max = n; // find maximum
       }
       }
       else{
       System.out.println("Number should be between 0 and 100");
       flag = 1;
       }
       }
       if(flag == 1)
       {
       flag = 0;
       continue;
       }
       else{
       break;
       }
   }
  
   System.out.println("Enter the largest number : " + max); // print the largest number
   System.out.println("Enter the smallest number : " + min); // print the smallest number
   System.out.println("Sum of all numbers : " + sum); // print the summation of number
   System.out.print("Print the original array : "); // print the original array
   for(int i = 0; i < 15; i++)
   {
   System.out.print(a[i] + " ");
   }
   }
}
OUTPUT :
