Frequently Asked Questions (FAQ)
Does this compiler support standard Java libraries?
Yes, the compiler uses a standard OpenJDK backend, supporting all standard Java libraries (java.util.*, java.io.*, java.math.*, etc.) out of the box.
Can I change the class and file name?
Absolutely. Unlike many online IDEs that force you to use a specific class name (like Main), you can customize the file name (and matching public class name) right from the interface.
