Is all the Classes and necessary Imports are there in code playground to develop or developing some stuff in java??

Question

Java Classes and Import

Answer 1

No: the classes for a graphical user interface (GUI) can't be used since you can only run your program in a console.
I suggest that if you want to develop a decent application, you do it on a computer with an IDE like Eclipse, Netbeans ...
