Java - Compare item of String array with a String

Question

I really don't understand what's wrong right now.

String s = "a,b,c,d";
String[] test = s.split(",");
System.out.println(test[0]);
System.out.println(test[0] == "a");

Console prints:

a
false

That doesn't make sense at all. test[0] is "a" and ("a" == "a") is false ?

Excuse me for my bad english. Thanks!

== tests for reference equality.

.equals() tests for value equality.

True, but a noob who doesn't know to compare strings with .equals() probably doesn't know what "reference equality" and "value equality" mean. – Solomon Slow Dec 15 '14 at 22:51
I also give a question url to larsklaus in my answer. So larsklaus can have more information about these. – Semih Eker Dec 15 '14 at 22:53
