The use of final denotes that a variable is a constant. For example:
final int PI = 3.14;
makes PI a constant. This is useful because now PI can't be changed, even accidentally, by you, the program, another programmer, or a user. Once a value is final, it is permanent, and can be used as a constant.
Note: usually programmers capitalize the names of constants, just to make it clear that the value is a constant.
Every method in java that isn't a class (static) method is automatically "virtual." If you want to disable virtual overrides, make the method "final" in the base class.
Final classes are sealed classes in java I guess.
In Java, you use the final modifier to prevent a class from having any subclasses.
-Public to all - Static to access with Class Name - Final to change( constant and not alowed to change) Just use it along with class name. (As implied above, a 'public static final' variable in Java is what other languages would call a Constant. )
A class declared as final means that no other class can inherit from it.
yes use the final keyword, normally variables declared final use all capital letters but this is not required final int A = 10;

In Java, the final keyword specifies that the object created cannot be further redefined or derived.
yes of course... using the final keyword
Declare the class as final. final class A{ ... }
we cannot use the staic keyword inside the method... But we can use the final keyword inside the method....
Java does not support Pointers and hence you cannot use it in Java.
A class declared as final means that no other class can inherit from it.
The final and finally keywords have no impact on the return type of a method in Java.
