Array Based Program - Largest Number, Smallest Number, Sum of Numbers Program- ICSE 2017 Computer Science

Write a program to input integer elements into an array of size 20 and perform the following operations:

(i) Display the largest number from the array.
(ii) Display the smallest number from the array.
(iii) Display the sum of all the elements of the array.

Java 

import java.util.Scanner;
class max_min_sum{
    public static void main(String[] args){
        Scanner in = new Scanner(System.in);
        int a[] = new int[20];
        int large = 0;
        int small = 0;
        int sum = 0;
        System.out.println("Enter 20 integers:");
        for(int i = 0; i < a.length; i++){
            a[i] = Integer.parseInt(in.nextLine());
            if(i == 0){
                large = a[i];
                small = a[i];
                sum = a[i];
            }
            else{
                if(large < a[i])
                    large = a[i];
                if(small > a[i])
                    small = a[i];
                sum += a[i];
            }
        }
        System.out.println("Largest number: " + large);
        System.out.println("Smallest number: " + small);
        System.out.println("Sum: " + sum);
    }
}
