What is the this keyword?

In Java, the .this keyword refers to the current object
We use it when a local variable and a class variable have
the same name, so it removes confusion. It is also used to
call another constructor in the same class, to pass the
current object to a method, or to return the current object
for method chaining. We mainly use this in constructor and
instance methods, but not in static methods.in short this
makes the code clean, avoids ambiguity and helps in reusing
