Answer / mmkrish
final --> is a keyword. It will be used for variables,
methods and classes also.
final variables --> Cannot change their value.
final Methods --> Cannot override or overload
final Class --> it can never be subclassed.
finally --> is a block used in exception handling. Genrally
used along with try.catch blocks... though try or catch
block executes...finally block should execute at last.
Means, if we have add finally block, it will call though
there is an exeption occurs.
finalize() --> It is a method. This will be used in garbage
collection of java. It will clear all the unused
resources...Cannot Override. It is a protected method.

Answer / chaithanya
Final:It is a keyword,constant like c/C++.suppose if we declare a=1,we cannot change that value over the programme.we cannot declare a++.
Finally():It is default block in exception handling.
Finalize():if an object holds non java resources,it must be releases resources before object is destroyed.called garbage collector.it runs periodically.we don't know when gc runs
so the programmer write in manually in finalise method invoked the gc before object is destroyed
