What is the difference between final, finally, and finalize?

Entry Java
Quick Answer final: variable can't be reassigned, method can't be overridden, class can't be extended. finally: block in try-catch that always runs (even if exception thrown) - used for cleanup (closing resources). finalize(): method called by GC before collecting an object - deprecated in Java 9, don't rely on it. All three are completely different concepts that happen to sound similar.

Answer

final: Constant or non-overridable.
finally: Executes after try/catch.
finalize: Called before garbage collection.
