## Problem Statement - 07A-2017

Write a program to input integer elements into an array of size 20 and perform the following operations:
(i) Display largest number from the array.
(ii) Display smallest number from the array.
(iii) Display sum of all the elements of the array.

## Solved Problem Understanding

```import java.util.Scanner;

public class ArrayOperations {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int[] numbers = new int[20];
System.out.print("Enter 20 numbers: ");
for (int i = 0; i < 20; i++) {
numbers[i] = scanner.nextInt();
}

int smallest = numbers[0];
int largest = numbers[0];
int sum = 0;
for (int i = 0; i < 20; i++) {
if (numbers[i] < smallest) { 17 smallest = numbers[i]; 18 } 19 if (numbers[i] > largest) {
largest = numbers[i];
}
sum = sum + numbers[i];
}
System.out.println("Smallest = " + smallest);
System.out.println("Largest = " + largest);
System.out.println("Sum = " + sum);
}
}```

Sample Output

Enter 20 numbers: 3 9 1 50 8 5 2 8 6 9 7 5 4 9 7 9 2 67 2 32
Smallest = 1
Largest = 67
Sum = 245
