Question: What Is Method Overriding In Java With Example?

Can we override private method in Java?

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..

How can we prevent method overriding?

That’s all about 3 ways to prevent a method from being overridden in Java. Remember, though syntactically you can use private, static and final modifier to prevent method overriding, but you should always use final modifier to prevent overriding. final is best way to say a method is complete and can’t be overridden.

Why method overriding is used?

The benefit of overriding is: ability to define a behavior that’s specific to the subclass type, which means a subclass can implement a parent class method based on its requirement. In object-oriented terms, overriding means to override the functionality of an existing method.

Why @override is used in Java?

@Override @Override annotation informs the compiler that the element is meant to override an element declared in a superclass. Overriding methods will be discussed in Interfaces and Inheritance. While it is not required to use this annotation when overriding a method, it helps to prevent errors.

Why we Cannot 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).

Is constructor overriding possible in Java?

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 we overload main method?
