Constructor:
Constructor must have same name as Class name.
Constructor does not have return type not even void.
Constructor does not support inheritance.
Constructor does not support overriding concept.
No need to call constructor explicitly it is called automatically at the time of object creation.
Generally we need constructor to write initialization logic.not business logic.
if we didn't provide constructor then JVM automatically add default constructor.
-----------------------------------------------
Method:
Method can have any name.
Method can have any return type.
We write method for modular programming.
In Program when repetitive statement occurred better to go for method.
it can be used to write business logic.
Need explicit calling by using object or Class name.
