SOLUTIONS
pg 78
Final
When applied to a variable (primitive): The value of the variable cannot change.
When applied to a variable (reference): The reference variable cannot point to any other object
on the heap.
When applied to a method: The method cannot be overridden.
When applied to a class: The class cannot be subclassed.
Finally
There is an optional finally block after the try block or after the catch block. Statements in the
finally block will always be executed (except if JVM exits from the try block). The finally block
is used to write the clean up code.
Finalize
This is the method that the JVM runs before running the garbage collector.
