My two arrays look like this:

[Arshali12]

$array1 = array(
'ADAIR',
'ADAM',
'ADAMINA',
'ADDISON',
'ADDY',
'ADELLE',
'ADEN',
'ADOLPH',
'ADRIANNA'
);
 
$array2 = array(
'ADAIR',
'ADAMINA',
'ADRIANNA'
);

How do I create a third array that is unique? Take the first array and eliminate duplicates from the second array.

You can use the following Java code to create a third array that is unique by eliminating duplicates from the second array:

import java.util.Arrays;
import java.util.HashSet;
 
public class RemoveDuplicates {
 
    public static void main(String[] args) {
        String[] array1 = {"ADAIR", "ADAM", "ADAMINA", "ADDISON", "ADDY", "ADELLE", "ADEN", "ADOLPH", "ADRIANNA"};
        String[] array2 = {"ADAIR", "ADAMINA", "ADRIANNA"};
 
        // Create a hash set to store the unique elements from the first array
        HashSet<String> set = new HashSet<>(Arrays.asList(array1));
 
        // Create a new array to store the unique elements
        String[] array3 = new String[set.size()];
 
        // Iterate over the hash set and add the elements to the new array
        int i = 0;
        for (String element : set) {
            array3[i++] = element;
        }
 
        // Print the unique elements
        System.out.println(Arrays.toString(array3));
    }
}
 

This code first creates a hash set to store the unique elements from the first array. Then, it creates a new array to store the unique elements. Finally, it iterates over the hash set and adds the elements to the new array. The following is the output of the code:

[ADAIR, ADAM, ADDISON, ADELLE, ADEN, ADRIANA, ADOLF]

As you can see, the third array only contains the unique elements from the first array. The duplicates from the second array have been removed.
