Answer 1

Explanation:

public class JavaExample {

public static void main(String[] args) {

double[] arr = {19, 12.89, 16.5, 200, 13.7};

double total = 0;

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

total = total + arr[i];

}

/* arr.length returns the number of elements

* present in the array

*/

double average = total / arr.length;

/* This is used for displaying the formatted output

* if you give %.4f then the output would have 4 digits

* after decimal point.

*/

System.out.format("The average is: %.3f", average)
