What is the difference between Final, Finally and Finalize in Java?

In Java, final, finally, and finalize are three distinct keywords with different meanings and purposes.

final: It is a keyword used to declare a variable, method, or class that cannot be modified or overridden once initialized or defined. When applied to a variable, it makes it a constant or immutable value that cannot be reassigned. When applied to a method, it makes it unmodifiable, and when applied to a class, it makes it uninheritable.

finally: It is a keyword used in try-catch-finally blocks to define a block of code that will be executed regardless of whether an exception is thrown or not. The finally block is usually used to release resources or perform clean-up operations that are required regardless of the outcome of the try block.

finalize: It is a method in the Object class that is called by the garbage collector when it is about to destroy an object that is no longer in use. The finalize() method can be overridden in a class to perform any necessary cleanup operations before the object is garbage collected.

In summary, final is used to define constants, unmodifiable variables, methods, or classes. finally is used to define a block of code that must be executed regardless of whether an exception is thrown or not, and finalize is a method that is called by the garbage collector to perform cleanup operations before an object is destroyed.
