You will need a Java Swing repl project in order to see the GUI elements of this program.
https://docs.oracle.com/javase/7/docs/api/javax/swing/JOptionPane.html

You should be able to create Java Swing projects on repl. If you want to paste your code to a new Java Swing project it should work granted the code works the way you want.
