How do you access final methods from Outer Classes?
The final modifier has nothing to do with access. If your "outer" classes can see the method, they can access them just like any other methods.
When do you declare a method final in java?
You declare a method final in Java when you do not want any subclasses of your class to be able to override the method. I have also heard that this allows the Java compiler to make more intelligent decisions. For example, it supposedly allows Java to decide when to make a method inline. (Note that this is all unconfirmed)
What is the type of class for which object cannot be created?
A class that is declared as "final" cannot be inherited.
How do you prevent method overriding in java?
Use the word "final" directly preceding your method declaration. The presence of final keyword directs java to ensure that, this particular method would not be overridden by any of its child classes.
What are sealed classes in java?
Final classes are sealed classes in java I guess.

When do you declare a method or class final?
if we declare a method as final then it can be changed.

Final classes are sealed classes in java I guess.
What is difference in use between interfaces and abstract classes in java?
While neither abstract classes nor interfaces can be instantiated in Java, you can implement methods in abstract classes. Interfaces can only define methods; no code beyond a method header is allowed.
What are the usages of keyword final in java?
It's a built-in keyword that defines an entity that cannot be later modified. It can be used in different aspects within your code (like setting a 'final' class, method (function), or variable).
Can you override an instance method and make it final?
No. Once a method is declared final in a class, no derivative of that class can override that method.
Discuss software engineering method?
Ok you start.
What is the final keyword in Java?
The final keyword precedes a declared constant which after Instantiation cannot be modified. Examples. final double PI = 3.14; PI = 1234; // does not compile //or final double ONE; ONE = 1; // Instantiated ONE = 2; // does not compile ---------------------------------------- final keyword can also apply to a method or a class. When applied to a method - it means the method cannot be over-ridden. Specially useful when a method assigns a state that should not be changed in the classes that inherit it, and should use it as it is (not change the method behaviour). When applied to a class it means that the class cannot be instantiated. A common use is for a class that only allows static methods as entry points or static final constants - to be accessed without a class instance. A good example is Java's: public final class Math extends Object
