Problem 150

Pre-populating Arrays

We’re going to learn how to easily give starting values to an array when creating it! (These are called “array initializers”.)

Use the provided code, and get it to compile.

public class GivingAnArrayABunchOfValuesAtOnce {
    public static void main(String[] args) {
        String[] arr1 = {"alpha", "bravo", "charlie"};

        System.out.print("The first array is filled with the following values:\n\t");
        for (int i = 0; i < arr1.length; i++)
            System.out.print(arr1[i] + " ");
        System.out.println();

    }
}

What You Should See

The first array is filled with the following values:
    alpha bravo charlie

After you add in the code you’re supposed to, you should see something more like this:

The first array is filled with the following values:
    alpha bravo charlie delta echo
The second array is filled with the following values:
    11 23 37 41 53

What You Should Do on Your Own

Assignments turned in without these things will receive no credit.

1. The first array only has three values in it. Add two more, for a total of five.
2. Create a second array of ints, and give it five starting values, too.
3. Print the second array.
