Download A04.txt and copy it into a new Eclipse project named {NetID}A04.
Rename (refector) {NETID}A03.java to {NETID}A04.java
Modify the return type of magicEightBallIf and magicEightBallCase so they return a String instead of printing the result.
Create a static method named createStringArray with an integer argument named "count". This method should create an array that is "count" long. It should fill the array with the results of "count" calls to magicEightBallCase. It should fill from index 0 to index "count-1". It should return the created array.

// of magicEightBallAnswers in the newly created array
String[] answers = magicEightBallAnswsers(100);
// We are looping over the array from 0 to array length
// printing the answer provided by the magicEightBallIf statements
// that were called in the magicEightBallAnswers method

System.out.println( i + ": " + answers[i] );

To complete the given task, follow the steps outlined below:
1. Download A04.txt file and save it in a suitable location on your computer.
2. Open Eclipse IDE and create a new project named {NetID}A04. Replace "{NetID}" with your actual NetID.
3. Copy the content of the downloaded A04.txt file and paste it into the {NetID}A04 project's main class file.
4. Rename the existing file {NETID}A03.java to {NETID}A04.java. Replace "{NETID}" with your actual NetID.
5. Modify the return types of the methods `magicEightBallIf` and `magicEightBallCase` to return `String` instead of printing the result. Update the method signatures as follows:
```java
public static String magicEightBallIf() {
// Existing code
}
public static String magicEightBallCase() {
// Existing code
}
```
6. Create a new static method named `createStringArray` that takes an integer argument named "count" and returns a `String` array. This method will create an array of length "count" and fill it with the results of "count" calls to the `magicEightBallCase` method. The method should fill the array from index 0 to "count-1". Use the following code:
```java
public static String[] createStringArray(int count) {
String[] answers = new String[count];
for (int i = 0; i < count; i++) {
answers[i] = magicEightBallCase();
}
return answers;
}
```
7. In the `main` method, replace the existing code with the following:
```java
public static void main(String[] args) {
magicEightBallIf();
magicEightBallCase();
magicEightBallLoop();
String[] answers = createStringArray(100);
for (int i = 0; i < answers.length; i++) {
System.out.println(i + ": " + answers[i]);
}
}
```
8. Now, you can run the program and check the output.
Please make sure you have the necessary Eclipse project set up and the A04.txt file downloaded before starting the steps mentioned above.
