The final is a modifier which you can apply to variable, methods and classes. If you make a variable final it means its value cannot be changed once initialized. finalize is a method, which is called just before an object is a garbage collected, giving it last chance to resurrect itself, but the call to finalize is not guaranteed. finally is a keyword which is used in exception handling along with try and catch. the finally block is always executed irrespective of whether an exception is thrown from try block or not.
