Is it possible to override the 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.

Can we override constructor in Java Javatpoint?

In Java, a constructor is the same as a method but the only difference is that the constructor has the same name as the class name. Remember that a constructor cannot be abstract, final, synchronized, and static. We cannot override a constructor.

Can constructor be extended in Java?

Calling Constructors in Superclasses In Java a class can extend another class. However, the subclass must call a constructor in the superclass inside of its the subclass constructors!

Can we override constructor of abstract class in Java?

Yes, an Abstract Class can have a Constructor. You Can Overload as many Constructor as you want in an Abstract Class.

Can we override variables in Java?

Variables are not polymorphic in Java; they do not override one another. So, as a variable is not overridden, no run time resolution is done for them, hence in the inheritance chain the variable value of the reference class is used when accessed instead of the object type.

What is @override in Java?

The @Override annotation is one of a default Java annotation and it can be introduced in Java 1.5 Version. It extracts a warning from the compiler if the annotated method doesn’t actually override anything. It can improve the readability of the source code.

Can we overload and override constructor in Java?

Can we override static method?

Static methods cannot be overridden because they are not dispatched on the object instance at runtime. The compiler decides which method gets called. Static methods can be overloaded (meaning that you can have the same method name for several methods as long as they have different parameter types).

Can constructor be private?

Yes. Class can have private constructor. Even abstract class can have private constructor. By making constructor private, we prevent the class from being instantiated as well as subclassing of that class.
