Final when written in front of a variable it means that the value assigned to that variable is constant.It is similar to const keyword as in C.
eg final int a=8;
This means that variable a ,through out the program will hav value of 8.
when written in front of method its mean that this method cannot be overwritten
when written in front of class it means that this class is final and cannot be inherited.eg string class is a final class
