Can we override the final method?
Any method that is declared as final in the superclass cannot be overridden by a subclass..
What is static and non static?
A static method belongs to the class, and you do not have to create an instance of the class to access the static method. … A non-static method belongs to an object of the class, and you have to create an instance of the class to access the non-static method.
Can we override private method?
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 constructor be private?
Yes, we can declare a constructor as private. If we declare a constructor as private we are not able to create an object of a class. We can use this private constructor in the Singleton Design Pattern.
Why main method is not overridden?
No, we cannot override main method of java because a static method cannot be overridden. The static method in java is associated with class whereas the non-static method is associated with an object. Static belongs to the class area, static methods don’t need an object to be called.
Can we make constructor static?
No, we cannot define a static constructor in Java, If we are trying to define a constructor with the static keyword a compile-time error will occur. In general, static means class level. A constructor will be used to assign initial values for the instance variables.
Can static methods use this?
The answer is no because static method does not need any object to be called, and this keyword always point to a current object of a class. simply if there is no object then how the keyword point to any current object so,we cannot use this keyword here.
Can we override constructor?
Constructor looks like method but it is not. It does not have a return type and its name is same as the class name. But, a constructor cannot be overridden.
Why we Cannot use this in static method?
The “this” keyword is used as a reference to an instance. Since the static methods doesn’t have (belong to) any instance you cannot use the “this” reference within a static method.
Can we use this () and super () in a method?
this() and super(), both are the constructors that’s why must be the first statement. But we can use both in a program. this(): It is used to call, same class Default or Parametrized Constructor. super(): It is used to call, immediate super/parent class Default or Parametrized Constructor.
Can we inherit private method in Java?
Yes. A java private member cannot be inherited as it is available only to the declared java class. Since the private members cannot be inherited, there is no place for discussion on java runtime overloading or java overriding (polymorphism) features.
Can you override a static method?
The answer is, No, you can not override static method in Java, though you can declare a method with the same signature in a subclass. It won’t be overridden in the exact sense, instead, that is called method hiding.
Can main method be final?
Yes, we can declare the main () method as final in Java. The compiler does not throw any error. If we declare any method as final by placing the final keyword then that method becomes the final method. The main use of the final method in Java is they are not overridden.
Which method Cannot be overridden?
A final method in a superclass cannot be overridden in a subclass—this guarantees that the final method implementation will be used by all direct and indirect subclasses in the hierarchy. Methods that are declared private are implicitly final , because it’s not possible to override them in a subclass.
