Java Tutorials - Polymorphism in Java | Compile time | RunTime Polymorphism

Polymorphism: One name, many forms:
- We've two types of polymorphism in java:
- Method Overloading
- Method Overoveriding

Method Overloading:
- When Function name is same, but arguments can be different.
- It's Compile Time Polymorphism

Method Overriding:
- When function name + return type + arguments are same.
- It's run time polymorphism, as on run time it decides, which methods should be executable
- Based on object, instance method of that object class will execute.
- For static method, it'll execute based on Reference variable as static method are class variable.
- For variable as well, it execute based on variable of Class.

Hi Sir, thanks for sharing. this is really helpful tutorial. Just one quick question. when Base a= new MethodOverriding(); why a.x ===> 1? I understand the concept of static binding and dynamic binding for methods, but x is a int variable, so i dont know what kind of binding will happen to this x variable.. could you please elaborate a bit? Thanks in advance!
