Creating a Digital Calculator using swing.

Could someone give me some advice on building an swing app that like a Digital calculator that will have one textfield and many buttons to input the digits, mathematical operators and the decimal symbol. Because I have searched through the internet and there are plenty of source codes but they don't give a clear understanding about what kind of techniques, methods that I should use. Please note that to explain the purpose of the methods, constructors that will be used.

When creating this should I have to use arrys or control arrays ?

If someone has time please enlighten me!

Thank You!

No.... you probably do not have to use arrys or control arrays.

And how would you expect that I know anything about what it is that you are trying to do? *I* would probably use a control array, what *you* should do is up to you, your abilities and your skill level. You do not have to use an arry (whatever that is) or a control array. Which is the only real answerable question that you asked. "When creating this should I have to use arrys or control arrays ?".

Ok then could you tell me if you want to make a calculator then what will you use in java?

I have one question when I click a button i.e. No 1 then the value will be assign to the textfield. Then I want to add no 3 like 13 then the first entered deleted the second value will be entered to the textfield. Then how am I able to put numbers as many as possible ?
