2. Common NamesJAVA ARRAYS PUBLIC NEW
Implement the findCommon method. When passed two arrays of names, it will return an array containing the names that appear 
in either or both arrays. The returned array should have no duplicates.

For example, calling CommonNames.findCommon(new String[]{'Ava', 'Emma', 'Olivia'}, new String[]{'Olivia', 'Sophia', 'Emma'}) 
should return an array containing Ava, Emma, Olivia, and Sophia in any order.


import java.util.Arrays;
public class CommonNames {
    
    public static String[] findCommon(String[] names1, String[] names2) {
        //throw new UnsupportedOperationException("Waiting to be implemented.");
        String [] res = (String[]) Stream.concat(Stream.of(names1), Stream.of(names2)).distinct().toArray(b -> new String[b]);
        
            
        return res;
    }
    
    public static void main(String[] args) {
        String[] names1 = new String[] {"Ava", "Emma", "Olivia"};
        String[] names2 = new String[] {"Olivia", "Sophia", "Emma"};
        System.out.println(String.join(", ", CommonNames.findCommon(names1, names2))); // should print Ava, Emma, Olivia, Sophia
    }
