Implicit Parameters and this

• Every method has one implicit parameter
• The implicit parameter is always called this
• Exception: Static methods do not have an implicit parameter (more on Chapter 9)

• double newBalance = balance + amount;
  // actually means
  double newBalance = this.balance + amount;

• When you refer to an instance field in a method, the compiler automatically applies it to the this parameter
