Contains method in Java doesn't exist?

Question

I am trying to make a java script for a mobile app check if a string contains specific characters.

if(fn.contains(" ")){

}

The fn variable is declared twice in the following:

private EditText fn;
final EditText fn = (EditText) findViewById(R.id.fn);

Not sure why this doesn't work. In android studio, the contains function highlights red as it doesn't exist. You can click here to see what I am talking about. Is there another method than this?

Include the declaration of `fn` in the post, and ensure you aren't shadowing the `String` type — Vince, Oct 21 '17 at 20:53
Java and JavaScript are two different languages. https://stackoverflow.com/questions/1789945/how-to-check-whether-a-string-contains-a-substring-in-javascript — KALALEX, Oct 21 '17 at 20:54
@KALALEX He never said JavaScript. He said a Java script (a script written in Java) — Vince, Oct 21 '17 at 22:24

That is an EditText not a string you must do first:

var str = fn.getText().toString()

if(str.indexOf(" ") !== -1;){ . . . }

When you put this, it worked: fn.getText().toString().contains(" ") – That1nub Oct 21 '17 at 21:06
dont tell you did this .. fn.contains(" ").getText().toString() xD – KALALEX Oct 21 '17 at 21:08
When you first said, I accidentally forgot to add the toString() – That1nub Oct 21 '17 at 21:13
