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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0cc153ae-b205-4fb2-9991-7cf6a21d5016%2Fd8551e13-46ec-4da2-b62c-f85a5c8856e3%2F9701q27_processed.png&w=3840&q=75)
