Here is one simple example:

String creditcard = JOptionPane.showInputDialog("Please enter you credit card number:");

For more examples, check the JOptionPane API and tutorial:

hmmm, I seem to be confused on this.

The assignment I have is as follows:

For this homework you are to produce the following methods that can be used to hide the JOptionPane code :

NamePurpose

getIntReturns an integer value

getDoubleReturns a double value

getStringReturns a string

outputMessage Outputs a messge via a JoptionPane

Well, as for the getString() method, you should be able to use the code I posted. Just put it inside a method that you call getString. The method should probably take one input argument, which is the message the user will see ("Please enter you credit card number:" in my example). And instead of storing the return value from the JOptionPane in a variable, you just return it from the getString method.

About the other methods you need to write, a good place to start would be the links I posted. It's your homework, after all, not mine :-)
