Hey

I'm trying to create a method that checks input from an array of
JTextField. I thought the trim() method from String automatically was
loaded, but I keep getting the "method not defined in class Form"  (of
type JInternalFrame)

I also thought that the return of JTextField.getText() was a String so
that I could use the trim() method in this, but no.

Some code:

public boolean checkInput(){
        for(JTextField content : textFields){
            if(trim(content.getText()).equals("")){
                return false;
            }
        }
        return true;
    }

    private String trim(String string){
        String s = trim(string);
        return s;
    }

Why am I getting the StackOverFlowException from this code? I'm
obviously missing something here.
