I THINK I'VE FINISHED THE MAIN JAVA CODE CORRECTLY, BUT I AM HAVING TROUBLE COMING UP WITH THE LAST 5 LINES OF CODE IN THE TESTER JAVA CODE.

MAIN JAVA CODE:

/**

* A class for a Person object that stores first name and last name.

*

* You should create the following methods:

* - Create a constructor that takes in a first name and last name

* - Create a getFullName method which returns the full name of the person

* - Create a getInitials method which returns the initials of the person

* - Create an equals method which returns whether two Person objest are equal

*/

public class Person

{

private String firstName;

private String familyName;

// Create a Constructor Method with two arguments to set the

// firstName and familyName instance variables

//-----------Start below here. To do: approximate lines of code = 3

//

public Person(String firstName, String familyName)

{

this.firstName = firstName;

this.familyName = familyName;

}

//-----------------End here. Please do not remove this comment. Reminder: no changes outside the todo regions.

// Create a public method called getFullName() that returns a string containing

// the first name followed by a blank space followed by the family name

//-----------Start below here. To do: approximate lines of code = 2

//

public String getFullName()

{

return firstName + " " + familyName;

}

//-----------------End here. Please do not remove this comment. Reminder: no changes outside the todo regions.

// Create a public method call getInitials() that returns a string containing the

// first letter of the first name followed by the first letter of

// the family name. Hint: use the substring method of class String.

//-----------Start below here. To do: approximate lines of code = 2

//

public String getInitials()

{

return firstName.substring(0,1) + familyName.substring(0,1);

}

//-----------------End here. Please do not remove this comment. Reminder: no changes outside the todo regions.

// Create a method boolean equals(Person other) - **using this exact method signature!!** -

// this method will return true if and only if the two person objects have the same first

// and last name.

//

// Don't forget you must use the equals method of class String when comparing familyName strings

// That means that the equals method of class Person will be calling the equals method of class String using

// the familyName variable but these are two different equals methods!!

//-----------Start below here. To do: approximate lines of code = 3

//

public boolean equals(Person other)

{

if(firstName == familyName)

{

return true;

}

else

{

return false;

}

}

//-----------------End here. Please do not remove this comment. Reminder: no changes outside the todo regions.

}

TESTER JAVA CODE:

import java.util.ArrayList;

/**

* This class tests the Person class. You should complete the findPerson method

*/

public class PersonTester

{

// Create a static method that returns true if a person with the given first name and last name

// is in the given ArrayList of Person objects

//

// HINT: Use the equals method you defined in Person

public static boolean findPerson(ArrayList people, String firstName, String lastName)

{

//-----------Start below here. To do: approximate lines of code = 5

//

//-----------------End here. Please do not remove this comment. Reminder: no changes outside the todo regions.

}
