Compile/Execute code in Java app

[Doctor Cactus]

Hi, I am writing a Java application and i need help. So, what i want to do is to compile and execute the code in a JTextArea which also shows errors(if any) on the screen. However, I also want to check that the code and the output of the program are correct, in the same way as on the Javala website. So, if the code and the output for a given exercise are correct, a message saying "Your program works correctly, exercise completed!" would appear on the screen. I have heard about the compiler class but I am unsure how to use it. Any ideas?

Help is greatly appreciated.

Basically what you want to do is, compile a Java class on the JTextArea. I've done quite anonymous thing this few years back. Write all of them in to a file and compile that file.

Save all content into a file. Then using a Process class compile the class.
