Suppose a is an array of values of type double that is partially filled. The array contains meaningful values in only the first numberUsed elements. where numberUsed is a variable of type int. Write some java code to display all the meaningful values in the array a.

Answer 1

public class PrintPartialArray {

    public static void main(String[] args) {
        double[] a = new double[10];
        a[0] = 5.5;
        a[1] = 4.7;
        a[2] = 9.1;
        a[3] = 3.0;
        int numberUsed = 4;

        for (int i = 0; i < numberUsed; i++) {
            System.out.println(a[i]);
        }
    }
