Array

The simplest way to start thinking about an array is as a collection, or a set of elements. In programming, these elements may be constants, variables, functions and pointers.

Question

New JAVA code can only be added between lines 9 and 10, as seen in image.

**Instructions:**

Declare and initialize a reference variable for an `ArrayList` named `animalsList` that stores items of type `String`. Read integer `numAnimals` from input. Then, insert `numAnimals` "sheep" at the end of `animalsList`.

**Example:**
If the input is 3, then the output is:
```
sheep sheep sheep
```

**Code Explanation:**

```java
import java.util.Scanner;
import java.util.ArrayList;

public class MakeAnimalsList {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
int numAnimals;
int i;

/* Variable declarations go here */

/* Your code goes here */

// Traversing a List using indexes
for (i = 0; i < animalsList.size(); ++i) {
System.out.print(animalsList.get(i) + " ");
}
System.out.println();
}
}
```

**Key Components:**

1. **Imports:**
- `java.util.Scanner`: Used for obtaining input from the user.
- `java.util.ArrayList`: Provides the `ArrayList` class to create dynamic arrays.

2. **Main Class and Method:**
- `MakeAnimalsList`: Class containing the main method.
- `main(String[] args)`: The entry point for the program.

3. **Variables:**
- `Scanner scnr`: For reading user input.
- `int numAnimals`: Stores the number of animals.
- `int i`: Loop counter.

4. **Comments:**
- Placeholder comments indicate where the variable declarations and core logic should be placed.

5. **Loop:**
- A `for` loop is used to traverse and print each element in `animalsList`.

This code snippet provides the structure, but the logic to read `numAnimals` and update `animalsList` is left for implementation. Fill in the necessary code under the indicated comment sections to complete the task.
