Write a java program that: Declare an array capable of holding 4 integers. It must be 4 integers only in the declaration. int[ ] array = new int[4]; Loop prompting the user to enter values to insert into the array until they enter a -1. For simplicity, we will assume users will only enter values greater than 0. You will need to check to see if the array is full before inserting the value in the next available spot in the array. If the array is full you will need to invoke the method, public static int[] expandArray(int[ ] array) that will double the size of the array and copy in the contents of the array. Include the method public static void displayArray(int[ ] array) that will display the contents of the array. Your main will contain the loop that prompts user to enter a value or -1 to indicate to quit. User will only enter values greater than 0. Insert the value into the next available slot in the array. You need to check to see if there is room in the array prior to inserting. After the user enters -1 and the loop terminates, display the contents of the array by calling displayArray. Hint: your main will want to keep track of the next available index into the array. When testing your program try to enter 10 values. Hint: See ExpandArray.java and for an example.

Write a java program that:

Declare an array capable of holding 4 integers. It must be 4 integers only in the declaration. int[ ] array = new int[4];
Loop prompting the user to enter values to insert into the array until they enter a -1. For simplicity, we will assume users will only enter values greater than 0.
You will need to check to see if the array is full before inserting the value in the next available spot in the array.
If the array is full you will need to invoke the method,

public static int[] expandArray(int[ ] array)

that will double the size of the array and copy in the contents of the array.

public static void displayArray(int[ ] array)

that will display the contents of the array.

Your main will contain the loop that prompts user to enter a value or -1 to indicate to quit. User will only enter values greater than 0. Insert the value into the next available slot in the array. You need to check to see if there is room in the array prior to inserting. After the user enters -1 and the loop terminates, display the contents of the array by calling displayArray. Hint: your main will want to keep track of the next available index into the array.
When testing your program try to enter 10 values.

Hint: See ExpandArray.java and for an example.

Sample run:

Please enter values to insert into the array or -1 to quit.

-1

The contents of the array:

Index Value

0 5

1 15

2 4

3 12

4 3

5 6
