Constructor

Ordinarily the data for the phone book would come from a disk file. In this example program, it will be "hard coded" into the constuctor:

class PhoneEntry
{
  String name;    // name of a person
  String phone;   // their phone number

  PhoneEntry( String n, String p )
  {
    name = n; phone = p;
  }
}

class PhoneBook
{ 
  PhoneEntry[] phoneBook; 

  PhoneBook()    // constructor
  {
    phoneBook = new PhoneEntry[ 5 ] ;

    phoneBook[0] = new PhoneEntry( "James Barclay", "(418) 665-1223" );
    phoneBook[1] = new PhoneEntry( "Grace Dunbar", "(860) 399-3044" );
    phoneBook[2] = new PhoneEntry( "Paul Kratides", "(815) 439-9271" );
    phoneBook[3] = new PhoneEntry( "Violet Smith", "(312) 223-1937" );
    phoneBook[4] = new PhoneEntry( "John Wood", "(913) 883-2874" );

  }

  PhoneEntry search( String targetName )  
  {
    . . . .     // use linear search to find the targetName
  }
}

Let us assume that the array will have every cell filled with a reference to a PhoneEntry object (as is true here.)
