Java™ How To Program (Early Objects), Tenth Edition

Section 8.4 Referring to the Current Object’s Members with the this Reference

• An instance method of an object implicitly uses keyword this (p. 322) to refer to the object’s instance variables and other methods. Keyword this can also be used explicitly.

• The compiler produces a separate file with the .class extension for every compiled class.

• If a local variable has the same name as a class’s field, the local variable shadows the field. You can use the this reference in a method to refer to the shadowed field explicitly.
