In this lecture we will see:
– Instance variable and Local variable
– Can we declare two or more variables with the same name?
– This keyword and its uses in Java

#1
Instance variable:- These variables are declared within a class but outside a method.
– These variables are created when we create an object and are destroyed when the object is destroyed.

Local variable:- These variables are declared within a method but do not get any default value.
– They are created when we enter a method or constructor and get destroyed when the call returns from the method.

#2
In Java, it is not allowed to declare two or more variables having the same name inside a scope either in class scope or method scope.
– The preference is always given to the local variable.
– Creating an object is not a good idea to solve the issue of conflicting names of instance and local variables.
– We can differentiate between local and instance variables by passing an object itself.
– Instead of writing and passing an object, we can simply use this keyword.

#3
This keyword:-
This keyword represents the current object.
– Current object is an object which is calling the method.
– This keyword is used to invoke the current class constructor.
– Using the ‘this’ keyword, we can return the current class instance.
– This keyword can be used as an argument in the constructor call.
