Cannot find symbol means that Java has no idea what you're trying to reference
In this case, it cannot figure out what JOptionPane is
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.
