What is method overriding explain with an example in Java?

If subclass (child class) has the same method as declared in the parent class, it is known as method overriding in Java. In other words, If a subclass provides the specific implementation of the method that has been declared by one of its parent class, it is known as method overriding.

What is method overriding explain with program?

Method overriding, in object-oriented programming, is a language feature that allows a subclass or child class to provide a specific implementation of a method that is already provided by one of its superclasses or parent classes.

What is method overloading and method overriding in Java with example?

Overloading vs Overriding: Difference between Method Overloading and Method Overriding

What are the rules for method overriding in Java?

Rules for Method Overriding in Java

• Overriding Access-Modifiers.
• The methods declared as ‘final’ cannot be overridden.
• The methods declared as ‘static’ cannot be overridden.
• Overriding Method must have the same return type (or subtype)
• Invoking Overridden Methods from child class.
• Overriding Constructors.

How is method overriding used in Java program?

Using a method in the child class that already exists in the parent class is referred as method overriding. In simple words, the child class is providing its own body to a method which is previously declared and defined by parent class, i.e. the base class method is overridden by the derived class.

Which is the argument list of the overriding method?

Argument list: The argument list of overriding method (method of child class) must match the Overridden method (the method of parent class). The data types of the arguments and their sequence should exactly match. Access Modifier of the overriding method (method of subclass) cannot be more restrictive than the overridden method of parent class.

Can a method override a method of a child class?

Overriding method (method of child class) can throw unchecked exceptions, regardless of whether the overridden method(method of parent class) throws any exception or not. However the overriding method should not throw checked exceptions that are new or broader than the ones declared by the overridden method.

Do you have to override all abstract methods in Java?

If a class is extending an abstract class or implementing an interface then it has to override all the abstract methods unless the class itself is a abstract class.
