The problem
Write a class named PhoneBookEntry that has fields for a person’s name and phone number. The class should have a constructor and appropriate accessor and mutator methods. Then write a program that creates at least five PhoneBookEntry objects and stores them in an ArrayList. Use a loop to display the contents of each object in the ArrayList.
Breaking it down
public class PhoneBookEntry {
public PhoneBookEntry(String name, String phoneNumber) {
super();
this.name = name;
this.phoneNumber = phoneNumber;
}
private String name;
private String phoneNumber;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPhoneNumber() {
return phoneNumber;
}
public void setPhoneNumber(String phoneNumber) {
this.phoneNumber = phoneNumber;
}
@Override
public String toString() {
return "PhoneBookEntry [name=" + name + ", phoneNumber="
+ phoneNumber + "]";
}
}
public static void main(String[] args) {
PhoneBookArrayList bookArrayList = new PhoneBookArrayList();
PhoneBookEntry entry1 = bookArrayList.new PhoneBookEntry("Jack", "920-456-2345");
PhoneBookEntry entry2 = bookArrayList.new PhoneBookEntry("Sam", "868-344-2345");
PhoneBookEntry entry3 = bookArrayList.new PhoneBookEntry("George", "414-234-2345");
PhoneBookEntry entry4 = bookArrayList.new PhoneBookEntry("Dimo", "608-049-2345");
PhoneBookEntry entry5 = bookArrayList.new PhoneBookEntry("Jenny", "971-456-2345");
List<PhoneBookEntry> phoneNumberEntries = new ArrayList<>();
phoneNumberEntries.add(entry1);
phoneNumberEntries.add(entry2);
phoneNumberEntries.add(entry3);
phoneNumberEntries.add(entry4);
phoneNumberEntries.add(entry5);
phoneNumberEntries.forEach(number -> System.out.println(number));
}Output
PhoneBookEntry [name=Jack, phoneNumber=920-456-2345]
PhoneBookEntry [name=Sam, phoneNumber=868-344-2345]
PhoneBookEntry [name=George, phoneNumber=414-234-2345]
PhoneBookEntry [name=Dimo, phoneNumber=608-049-2345]
PhoneBookEntry [name=Jenny, phoneNumber=971-456-2345]
