Frustrating. – Jedona - Compiler for Java Review

This compiler is so frustrating to work with. There are also too many pop-up ads.. It can execute a simple Java program, but this app isn't suitable for any serious programming. It can't read any data from files. There is an input screen, but it won't allow any interactivity. It could allow multiple classes, but they must be written in a single page that must include the default main procedure.
