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 subclass provides the specific implementation of the method that has been provided by one of its parent class, it is known as method overriding.
Let's understand the problem that we may face in the program if we don't use method overriding.
Problem is that I have to provide a specific implementation of run() method in subclass that is why we use method overriding.
In this example, we have defined the run method in the subclass as defined in the parent class but it has some specific implementation. The name and parameter of the method is same and there is IS-A relationship between the classes, so there is method overriding.
Consider a scenario, Bank is a class that provides functionality to get rate of interest. But, rate of interest varies according to banks. For example, SBI, ICICI and AXIS banks could provide 8%, 7% and 9% rate of interest.
No, static method cannot be overridden. It can be proved by runtime polymorphism, so we will learn it later.
because static method is bound with class whereas instance method is bound with object. Static belongs to class area and instance belongs to heap area.
No, because main is a static method.
Let's see the concept of method overriding with access modifier.
Let's see the concept of method overriding with exception handling.
