This used implicitly and explicitly to refer to members of an object.
Every object can access a reference to itself with keyword this (sometimes called the this
reference). When a non-static method is called for a particular object, the method’s body
implicitly uses keyword this to refer to the object’s instance variables and other methods.
This enables the class’s code to know which object should be manipulated. As you’ll see in
Fig. 8.4, you can also use keyword this explicitly in a non-static method’s body.
Section 8.5 shows another interesting use of keyword this. Section 8.11 explains why
keyword this cannot be used in a static method
