For developing a calculator i need to use the 'append ()' to enter text into the textfield as shown in the tutorials.For example ,to add '1' to the textfield i need to write this code 'textfield.append("1")' which isn't workin in my case.....I've uploaded the screenshot here.......please help....why isn't it working?What should i do?

why isn't it working?

Please explain what "not working" means?
Are there compiler errors?

Where is the variable text defined? What is it?
Is the append() method defined for that class? Look in the API doc to see.

Yes there are compiler errors..........you can see it in the picture which i've posted.The variable name of the textfield is 'text'.This is the error thrown "the method append(string) is undefined for the type JtextField".

[Norm]

the method append(string) is undefined for the type JtextField

The error message seems very clear.
Did you read the API doc for JTextField to verify that the error message was correct?

class JTextField don't have 'append' method , use JTextArea , instead .
