Get input from a jtextfield

How would I get user input from a jtextfield in my GUI? Would I use java.util.Scanner or another class?

JTextField a = new JTextField("Input Here")
//Put calculation formula here
Solution

  • A GUI is an event driven environment. You will need to listen to the events that the component is producing.

    For example, JTextField raises ActionEvents (amongst others) which tells you that the user has (on most systems) pressed the Enter key.
