Is is necessary to mention "this" keyword for referring current object?
Any alternative for using 'this' keyword

No alternative. Why would you need one?
Think of "this" as an implicit first parameter of any non-static method of your class.
You can omit the "this." prefixing for attributes of the class inside a method of the class, providing that there are no parameter or variable of the same name in that method. I would suggest to always write it regardless so that readers of your code (including you) immediately understand that you are manipulating an attribute of the class, and not just a variable.

you should only really use "this" if you are overloading a variable. otherwise it is basically redundant.
