Comparing String To Array Element ?

I have the following code:

Java Code:

public class Equals {

        String[] s1 = {"red", "white", "black", "blue"};
        String[] s2 = {"red", "black", "green"};
        String[] s3 = {"red", "green"};

What I need is to give me the following output:

Select Strings:







s1,s2,s3

Comparing String s1, s2, s3

red 3 matches.







black 2 matches.







green 2 matches.

Someone can help me?

Thanks a lot!

Greetings!
