Designing the Public Interface of a Class: Constructor Definition

• A constructor initializes the instance variables
• Constructor name = class name
  

  public BankAccount()
  {
     // body--filled in later
  }

• Constructor body is executed when new object is created
• Statements in constructor body will set the internal data of the object that is being constructed
• All constructors of a class have the same name
• Compiler can tell constructors apart because they take different parameters
