elements into an array of size 20 and
perform the following operations in java:
[15]
(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

Answer:

Program:-

import java.util.*;

public class Main

{

public static void main(String args[])

{

Scanner in=new Scanner(System.in);

int a[]=new int[20];

int max=0,min=0,sum=0;

System.out.println("Enter the 1st element of the array");

a[0]=in.nextInt();

max=a[0];

min=a[0];

System.out.println("Enter the remaining elements of the array:");

for(int i=1;i<a.length;i++)

{

a[i]=in.nextInt();

if(a[i]>max)

max=a[i];//If any element of the array is found greater than max it is stored in max

if(a[i]<min)

min=a[i];//If any element of the array is found smaller than min it is stored in min

}

for(int i=0;i<a.length;i++)

{

sum=sum+a[i];//For calculating the sum

}

System.out.println("The greatest element="+max);

System.out.println("The smallest element="+min);

System.out.println("The sum of the elements of the array="+sum);

in.close();

}

}

Output is attched.
