Can anyone help me out I'm looking to build a simple application that has a jtextfield so the user enters a number and the value is saved as a variable. How would I archive this?

Can you clarify "archive"?

Do you mean you want store the value so that it can be retrieved? You would need to either use a back end storage like a database or write the variable value to a file and then read the file from the application.

Sorry I'm on the phone I mean achieve. Basically I want to take whatevers in the jtextfield and save it as a variable and then print it out on screen.

If you want to accept it as a string you could do it like this

String yourString = yourJTextField.getText();

Or like this as an integer value

int myInt = Integer.parseInt(yourJTextField.getText());

You'll need to create some sort of Action Event - button event ideally to trigger the variable value being set to the value of the JTextField.

Thanks very much that works perfect i have another question whats the best event to use on the main window to trigger the event code? i want everything to update without pressing a button

Have a look at the link in my last post, you could add a component/frame/focus event listener to update the main frame, but I'd recommend using a component like a button event to trigger the update
