Trouble apending a textArea with the contents of a parameter

Hi all!!

I have a method

Code Java:

public String methodTester(Method [] mtd)

which does the following amongst other things:

Code Java:

 
for (Method m : mtd) { // introducing all methods in the array
            if (!(m.getName().startsWith("test"))) { //
 
                    return("Object or Class does not contain such methods");
 
            }else {
                    result = result + m.getName();
            }
 
            // more code here
 
return result;

Then I have a listener on a button and when clicked it is supposed to display the results on a textArea on a frame. The frame works fine and it outputs all correctly except the third line which I write below which gives me an error “cannot find symbol”.

Code Java:

 
               ClassAnalyzer analyzer = new ClassAnalyzer(textField.getText());
 
                textArea.append(analyzer.getClassMember()+ "\n"); // this works fine
 
                textArea.append(analyzer.methodTester(mtd)); // this does not work

Can anyone please help me?

Thank you and best regards,
