inner classes and local variables...

[Sriram Sharma]

Method local inner classes cannot access the method's local variables. This is understandable as the local variables will be blown out of stack once the control comes out of the method.
But, I also found that local variables marked as final can be accessed by the method local inner class.
What is the reason for this? Won't the final variable, local to a method, be thrown out of the stack once control comes out of the method?
Pls explain.

Thanks in advance
Sriram.

If the local variable (or method parameter) is marked final, then it is copied into the object instantiated from the method local class. You can pass primitives and object references in this way.

Thanks Barry :-)

hmm btw how do we mark the method parameter as final?

like this:

private void test(final int a){}

in the body of method test, you cannot change variable a by assigning a new value to it.
