What is inheritance and how is it useful in Java?

Is overriding possible in Java?
In Java, methods are virtual by default. We can have multilevel method-overriding. Overriding vs Overloading : … Overriding is about same method, same signature but different classes connected through inheritance.
What is the main purpose of inheritance?

What are the disadvantages of inheritance?
- One of the main disadvantages of inheritance is the increased time/effort it takes the program to jump through all the levels of overloaded classes. …
- Main disadvantage of using inheritance is that the two classes (base and inherited class) get tightly coupled.
Why inheritance is needed?
Inheritance enables code reusability and saves time. Inheritance is used to declare characteristics of classes inheriting it,without giving its implementation.It is one of the most important concept of OOPS. Inheritance is an object-oriented property of java. Inheritance is very essential for expandability.
What are the 4 basics of OOP?

What is advantage of inheritance in Java?
Benefits of Inheritance
Inheritance helps in code reuse. The child class may use the code defined in the parent class without re-writing it. Inheritance can save time and effort as the main code need not be written again. Inheritance provides a clear model structure which is easy to understand.
