1.3.1 Defining Classes to Represent Compound Data

We have finally introduced enough Java mechanics to define the data required to represent the department directory entries described in Section 1.1.2. Recall that a directory entry is a object with the following fields and methods:

Fields:
    String name;
    String address;
    String phone;
	
Methods:
    String getName();
    String getAddress();
    String getPhone();

In Java, we define this new form of data as the class

class Entry {
  /* fields */
  String name;	
  String address;
  String phone;

  /* accessors */
  String getName() { return this.name; }
  String getAddress() { return this.address; }
  String getPhone() { return this.phone; }
}
