Question
Complete the following code to make a copy of the first half of an array of strings.
Only edit code within the /* Your code goes here */ portions
![### Java Program: Copy Half of an Array
#### Code Overview
The following Java program demonstrates a method that copies the first half of an array. If the length of the array is odd, the middle value is not copied.
```java
import java.util.Arrays;
public class CopyHalf {
/**
* Copies the first half of an array. If the length is odd,
* don't copy the middle value.
* @param values an array
* @return a copy of the first half of values
*/
public static /* Your code goes here */ copyHalf(String[] values) {
/* Your code goes here */
}
public static void main(String[] args) {
String[] arr1 = { "Mary", "had", "a", "little", "lamb" };
System.out.println("Full Array 1: " + Arrays.toString(arr1));
System.out.println("Half Array 1: " + Arrays.toString(copyHalf(arr1)));
System.out.println();
String[] arr2 = { "its", "fleece", "was", "white", "as", "snow" };
System.out.println("Full Array 2: " + Arrays.toString(arr2));
System.out.println("Half Array 2: " + Arrays.toString(copyHalf(arr2)));
}
}
```
#### Functionality
- **Method `copyHalf`:**
- Takes an array of strings as input.
- Returns a new array containing the first half of the input array.
- If the array length is odd, the middle element is not included in the new array.
- **Main Method:**
- Two arrays (`arr1` and `arr2`) are declared and initialized with string elements.
- The full content of each array is printed.
- The content of the half-copied arrays returned by `copyHalf` is printed.
#### Terminal Output
The terminal shows some output related to an execution:
- The beginning section shows numbers `8 2 4 6 8`.
- It lists some names: `Fred Amy Cindy Henry`.
- Demonstrates entering scores with the output of some numbers `12 25 20 10 -1`.
- Indicates the program completed successfully with the message: "Process finished with exit code 0."
This program is ideally suited for beginners learning Java, focusing on array manipulation and string handling.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd6e87594-a0d7-48c0-af39-cad58e8108aa%2Feb2db406-0d53-4d4d-afda-4917c45cb9db%2F8hzlqpn_processed.jpeg&w=3840&q=75)
