Question

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.

Answer 1

import java.util.Scanner;
class LargeSmallSum {
public static void main(String args[ ]) {
int n;
int max, min, sum = 0;
int i, j;
Scanner s = new Scanner(System.in);
System.out.print(“Enter no. of elements you want in array:”);
n = s.nextlnt();
int a[ ] = new int[n];
System.out.println(“Enter all the elements:”);
for (i = 0; i < n; i+ +) {
a[i] = s.nextlntO;
}
max = a[0];
min = a[0];
for(i = 0; i < n ; i + +) { if(a[i] > max) {
max = a[i];
}
if (a[i] < min) {
min = a[i];
}
}
System.out.println(“Maximum Number is:”+max);
System.out.println(“Smallest Number is:” +min);
for(i = 0; i < n; i+ +) {
sum = sum + a[i];
}
System.out.println(“Sum of the Numbers is:” +sum);
}
}
