Does using GUI's JFrame cancels the Scanner class?

Question

I created a JFrame window with some buttons and I want to make it when a user click a specific button a method will be launched and the method will use a scanner object to pick up information from the user.

For some reason after I click that button from the frame, the method launches but I am not able to type any info.

Is there a way to use JFrame and Scanner class at the same application?

Answer 1

Yes, there is definitely a way to use both of them at the same time. You just cannot use the Scanner to take input from the command line.

A program in Java should either be a GUI application or a Console application, but not both. Once you bring up a JFrame, your code should not be reading from console. What you should do is adding input fields to your GUI (e.g. a JTextField) and read a String from it. You can pass the String that you read to a Scanner to subdivide it into tokens. Alternatively, you could make multiple text input fields, and take your input that way.
