Can we inherit final method?

Ans) Yes, final method is inherited but you cannot override it.

Can you inherit final methods?

No, we cannot override a final method in Java. The final modifier for finalizing the implementations of classes, methods, and variables. We can declare a method as final, once you declare a method final it cannot be overridden.

Can you inherit from a final class?

The main purpose of using a class being declared as final is to prevent the class from being subclassed. If a class is marked as final then no class can inherit any feature from the final class. You cannot extend a final class.

Can you inherit methods?

The inherited methods can be used directly as they are. You can write a new instance method in the subclass that has the same signature as the one in the superclass, thus overriding it. You can write a new static method in the subclass that has the same signature as the one in the superclass, thus hiding it.

Which method Cannot be inherited in Java?

Q) Which cannot be inherited from a base class in Java programming. Constructor of a class cannot be inherited. But note that they can be invoked from a derived class. final method can be inherited just they cannot be overridden in sub class.

can we inherit and override final method in java?

Can final method be overridden?

You can declare some or all of a class's methods final. You use the final keyword in a method declaration to indicate that the method cannot be overridden by subclasses. The Object class does this—a number of its methods are final .

Can final method be overloaded?

Can We Override a Final Method? No, the Methods that are declared as final cannot be Overridden or hidden.

Which class Cannot be inherited?

An abstract class cannot be inherited by structures. It can contains constructors or destructors. It can implement functions with non-Abstract methods.

Can we achieve abstraction without encapsulation?

The object is the abstract form of the real-world and its details are hidden using encapsulation. Thus encapsulation is required for abstraction.

Can private variables or methods inherit?

private variables / members are not inherited. That's the only answer. Providing public accessor methods is the way encapsulation works. You make your data private and provide methods to get or set their values, so that the access can be controlled.

What happens if method is final?

If we declare a method as final, then it cannot be overridden by any subclasses. And, if we declare a class as final, we restrict the other classes to inherit or extend it. In other words, the final classes can not be inherited by other classes.

Can we overload final method in Java?

yes overloading final method is possible in java.As final methods are restricted not to override the methods. while overloading argument list must be different type of the overloading method.

Can we override static method?

Overloading is the mechanism of binding the method call with the method body dynamically based on the parameters passed to the method call. Static methods are bonded at compile time using static binding. Therefore, we cannot override static methods in Java.

Can we have final method in interface?

If you make an interface final, you cannot implement its methods which defies the very purpose of the interfaces. Therefore, you cannot make an interface final in Java. Still if you try to do so, a compile time exception is generated saying “illegal combination of modifiers − interface and final”.

Can private method be inherited in Java?

private methods are not inherited. A does not have a public say() method therefore this program should not compile.

Can abstract class have constructor?

Like any other classes in Java, abstract classes can have constructors even when they are only called from their concrete subclasses.

Can we make instance of abstract class?

Abstract classes cannot be instantiated, but they can be subclassed. When an abstract class is subclassed, the subclass usually provides implementations for all of the abstract methods in its parent class. However, if it does not, then the subclass must also be declared abstract .

Can we achieve 100 abstraction using abstract class?

Note: Using an abstract class, we can achieve 0-100% abstraction. Remember that, we cannot instantiate (create an object) an abstract class. An abstract class contains abstract methods as well as concrete methods.

Can we inherit abstract method in Java?

If a class is declared abstract, it cannot be instantiated. To use an abstract class, you have to inherit it from another class, provide implementations to the abstract methods in it. If you inherit an abstract class, you have to provide implementations to all the abstract methods in it.

Can static class be inherited?

Static classes are sealed and therefore cannot be inherited. They cannot inherit from any class except Object. Static classes cannot contain an instance constructor. However, they can contain a static constructor.

Can abstract methods be inherited in Java?

Abstract Classes and Methods

Abstract class: is a restricted class that cannot be used to create objects (to access it, it must be inherited from another class).

Can we write final method in abstract class?

Hence, a final class cannot contain abstract methods whereas an abstract class can contain a final method.

Can we override private static final methods?

No, we cannot override private or static methods in Java. Private methods in Java are not visible to any other class which limits their scope to the class in which they are declared.

Can method be declared static?

Static methods

When a method is declared with the static keyword, it is known as the static method. The most common example of a static method is the main( ) method. As discussed above, Any static member can be accessed before any objects of its class are created, and without reference to any object.

Can we overload main method?

Yes, we can overload the main method in Java, but When we execute the class JVM starts execution with public static void main(String[] args) method.
