What are the advantages of passing this into a method instead of the current class object itself?

Question

Doesn't this refer to the current class object?

Answer 1

Yes, you are right, 'this' refers to the current class object. Despite this though, if you're looking to learn java, there are a couple of advantages of passing 'this' to a function and not the current class object. 

• Since 'this' is a final variable, it cannot be assigned to a new value whilst the current class object may not be final and is susceptible to change. 
• Its implementation can be used for a synchronized block.
