FAQ

Why do Java code obfuscation?

The common reason is to reduce source code readability and minimize risks of direct copying, plagiarizing or easily understanding core logic.

Is it suitable for course assignments and small project distribution?

Yes. Especially in scenarios where code needs to be shared but source shouldn't be too obvious, obfuscation is more helpful.

Is Java obfuscation the same as encryption?

No. Obfuscation focuses more on reducing readability and understanding difficulty, not providing complete encryption protection.

What are online tools more suitable for?

More suitable for quick processing, demos and lightweight protection methods to help with basic readability processing before sharing or publishing.
