I'm doing an address book as part of a school assignment and I have it mostly figured out, but I'm stuck on one part. Here's my code first. I have an AddressBook class that contains variables and appropriate getter and setter methods to change/return the information for each person in the book. Then I have a TestAddressBook class with a method main that demonstrates how the address book works. The only thing I'm stuck on is the final requirement, where I'm asked to compare two names and see if they're equal and print the results. I have the program designed the way I want it but for some reason when I do the comparison, it doesn't print the comparison results. It just prints nothing at all. I've got to be missing something obvious. Here's the code for the classes.
AddressBook...
public class AddressBook {
private String firstName;
private String middleName;
private String lastName;
private String homeAddress;
private String homePhone;
private String cellPhone;
private String businessPhone;
private String skypeId;
private String facebookId;
private String personalWebSite;
public AddressBook(String firstName, String middleName, String lastName,
String homeAddress, String homePhone, String cellPhone,
String businessPhone, String skypeID, String facebookID,
String personalWebSite) {
this.firstName = firstName;
this.middleName = middleName;
this.lastName = lastName;
this.homeAddress = homeAddress;
this.homePhone = homePhone;
this.cellPhone = cellPhone;
this.businessPhone = businessPhone;
this.skypeId = skypeID;
this.facebookId = facebookID;
this.personalWebSite = personalWebSite;
}
public AddressBook(String firstName) {
this.firstName = firstName;
}
public AddressBook(String firstName, String middleName) {
this.firstName = firstName;
this.middleName = middleName;
}
public AddressBook(String firstName, String middleName, String lastName) {
this.firstName = firstName;
this.middleName = middleName;
this.lastName = lastName;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getMiddleName() {
return middleName;
}
public void setMiddleName(String middleName) {
this.middleName = middleName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String getHomeAddress() {
return homeAddress;
}
public void setHomeAddress(String homeAddress) {
this.homeAddress = homeAddress;
}
public String getHomePhone() {
return homePhone;
}
public void setHomePhone(String homePhone) {
this.homePhone = homePhone;
}
public String getCellPhone() {
return cellPhone;
}
public void setCellPhone(String cellPhone) {
this.cellPhone = cellPhone;
}
public String getBusinessPhone() {
return businessPhone;
}
public void setBusinessPhone(String businessPhone) {
this.businessPhone = businessPhone;
}
public String getSkypeId() {
return skypeId;
}
public void setSkypeId(String skypeId) {
this.skypeId = skypeId;
}
public String getFacebookId() {
return facebookId;
}
public void setFacebookId(String facebookId) {
this.facebookId = facebookId;
}
public String getPersonalWebSite() {
return personalWebSite;
}
public void setPersonalWebSite(String personalWebSite) {
this.personalWebSite = personalWebSite;
}
public static String compareNames(String name1, String name2) {
String nameEquals;
if ( name1.equals(name2) ) {
nameEquals = (name1 + " and " + name2 + " are equal names.");
return nameEquals;
}
else {
nameEquals = (name1 + " and " + name2 + " are not equal names.");
return nameEquals;
}
}
}
Test Class...
public class TestAddressBook {

System.out.println( "First Name: " + entry1.getFirstName() );
System.out.println( "Middle Name: " + entry1.getMiddleName() );
System.out.println( "Last Name: " + entry1.getLastName() );

well you have it good look at this
package teteo;
public class TestAddressBook {
public static void main(String[] args) {
System.out.println("ENTRY 1");
AddressBook entry1 = new AddressBook("Robert", "James", "Smith", "3 Fake St",
"222-321-8371", "222-423-2382",
"222-438-2918", "bob483", "bobfb493",
"http://www.freewebhost.com/bob848");
System.out.println( "First Name: " + entry1.getFirstName() );
System.out.println( "Middle Name: " + entry1.getMiddleName() );
System.out.println( "Last Name: " + entry1.getLastName() );
System.out.println( "Address: " + entry1.getHomeAddress() );
System.out.println( "Home Phone: " + entry1.getHomePhone() );
System.out.println( "Cell Phone: " + entry1.getCellPhone() );
System.out.println( "Business Phone: " + entry1.getBusinessPhone() );
System.out.println( "Skype ID: " + entry1.getSkypeId() );
System.out.println( "Facebook ID: " + entry1.getFacebookId() );
System.out.println( "Personal Website: " + entry1.getPersonalWebSite() );
System.out.println("\nENTRY 2");
AddressBook entry2 = new AddressBook("Robert", "James", "Smith", "56 Outtamy Way",
"564-342-8372", "564-283-9832",
"564-293-3489", "brucie392", "brucieface28",
"http://www.freewebhost.com/carteristheman");
System.out.println( "First Name: " + entry2.getFirstName() );
System.out.println( "Middle Name: " + entry2.getMiddleName() );
System.out.println( "Last Name: " + entry2.getLastName() );
System.out.println( "Address: " + entry2.getHomeAddress() );
System.out.println( "Home Phone: " + entry2.getHomePhone() );
System.out.println( "Cell Phone: " + entry2.getCellPhone() );
System.out.println( "Business Phone: " + entry2.getBusinessPhone() );
System.out.println( "Skype ID: " + entry2.getSkypeId() );
System.out.println( "Facebook ID: " + entry2.getFacebookId() );
System.out.println( "Personal Website: " + entry2.getPersonalWebSite() );
System.out.println("\nENTRY 3");
AddressBook entry3 = new AddressBook("Susan", "Anne", "Peters", "6 Madeup Blvd",
"736-453-1238", "736-392-2385",
"736-926-2439", "anniep", "susananne",
"http://www.freewebhost.com/Susanspage");
System.out.println( "First Name: " + entry3.getFirstName() );
System.out.println( "Middle Name: " + entry3.getMiddleName() );
System.out.println( "Last Name: " + entry3.getLastName() );
System.out.println( "Address: " + entry3.getHomeAddress() );
System.out.println( "Home Phone: " + entry3.getHomePhone() );
System.out.println( "Cell Phone: " + entry3.getCellPhone() );
System.out.println( "Business Phone: " + entry3.getBusinessPhone() );
System.out.println( "Skype ID: " + entry3.getSkypeId() );
System.out.println( "Facebook ID: " + entry3.getFacebookId() );
System.out.println( "Personal Website: " + entry3.getPersonalWebSite() );
String equal = AddressBook.compareNames(entry1.getFirstName() + " " +
entry1.getMiddleName().charAt(0) + " " +
entry1.getLastName(),
entry2.getFirstName() + " " +
entry2.getMiddleName().charAt(0) + " " +
entry2.getLastName() );
System.out.println(equal);
}
}
now it is equals, but you must know that in order to do this you should use
compareTo() or comparable look at this
https://www.javacodegeeks.com/2013/03/difference-between-comparator-and-comparable-in-java.html
What would happen if you use a map? where it depends of a key, you will get duplicate values, i mean if you won't use that it is ok your code, but if you will use it then look an eye in there :)
