final keyword in java

[Shashank Rudra]

Hi to All,

1. How the final methods are more optimized in terms of being called/invoked

2. When talking about final parameters to method -

Final parameters are not considered part of the method signature, and are ignored by the compiler when resolving method calls. Parameters can be declared final (or not) with no influence on how the method is overriden.

What does this really mean??

Thanks in advance for taking time out and answering them.

for example if there is a method
draw(final int x,final int y)
{
}

then the you can overload that method with this
draw(int a,int b)
{
}

final has no effect on method signature

Thanks Ankur for helping me understand this.

Will someone please comment on as to How the final methods are optimized as compiler gets us bytecode for them.TIA.
