Define a class to declare an array of size 20 of double datatype, accept the elements into the array and perform the following:
Calculate and print the sum of all the elements.
Calculate and print the highest value of the array.
Answer
import java.util.Scanner;
public class KboatSDASumMax
{
public static void main(String args[]) {
Scanner in = new Scanner(System.in);
double arr[] = new double[20];
System.out.println("Enter 20 numbers:");
for (int i = 0; i < 20; i++) {
arr[i] = in.nextDouble();
}
double max = arr[0], sum = 0;
for (int i = 0; i < arr.length; i++) {
if (arr[i] > max)
max = arr[i];
sum += arr[i];
}
System.out.println("Sum = " + sum);
System.out.println("Highest Value = " + max);
}
}Output
