Are private methods final?
When we use final specifier with a method, the method cannot be overridden in any of the inheriting classes.
Methods are made final due to design reasons.
Since private methods are inaccessible, they are implicitly final in Java..
Can we override main method?
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. … Therefore, it is not possible to override the main method in java.
Can abstract class have constructor?
Yes! Abstract classes can have constructors! Yes, when we define a class to be an Abstract Class it cannot be instantiated but that does not mean an Abstract class cannot have a constructor. Each abstract class must have a concrete subclass which will implement the abstract methods of that abstract class.
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. If you try to write a super class’s constructor in the sub class compiler treats it as a method and expects a return type and generates a compile time error.
Can a static method be overridden?
Can we Override static methods in java? We can declare static methods with same signature in subclass, but it is not considered overriding as there won’t be any run-time polymorphism. Hence the answer is ‘No’.
Can we override static method in child class?
No, we cannot override static methods because method overriding is based on dynamic binding at runtime and the static methods are bonded using static binding at compile time. … If we call a static method by using the child class object, the static method of the child class will be called.
Can you declare an overridden method to be static if the original method is not static?
Can you declare the override method as static while the original method is non-static ? Answer: No, you cannot, the signature of the virtual method must remain the same, only the keyword “virtual” is changed to keyword “override” .
Which method Cannot be overridden?
A method declared final cannot be overridden. A method declared static cannot be overridden but can be re-declared. If a method cannot be inherited, then it cannot be overridden. A subclass within the same package as the instance’s superclass can override any superclass method that is not declared private or final.
Can we declare static method as private?
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.
What is method hiding?
Java 8Object Oriented ProgrammingProgramming. When super class and sub class contains same method including parameters and if they are static. The method in the super class will be hidden by the one that is in the sub class. This mechanism is known as method hiding.
Can we override protected method as private?
Yes, the protected method of a superclass can be overridden by a subclass. If the superclass method is protected, the subclass overridden method can have protected or public (but not default or private) which means the subclass overridden method can not have a weaker access specifier.
Why can we not 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 inherit static class?
Creating a static class is therefore basically the same as creating a class that contains only static members and a private constructor. … Static classes are sealed and therefore cannot be inherited. They cannot inherit from any class except Object. Static classes cannot contain an instance constructor.
Can we override final method?
The method declaration should be the same as that of the method that is to be overridden. The class (subclass) should extend another class (superclass), prior to even try overriding. The Sub Class can never override final methods of the Super Class.
Why is main method static?
Java main() method is always static, so that compiler can call it without the creation of an object or before the creation of an object of the class. … Static method of a class can be called by using the class name only without creating an object of a class.
