In the next steps you will take each of the removes, look for it in the membership, and remove it if found or print an error if not found. For Person class objects, we choose to use email names to test for equality because these are unique to a Person. o o Run the code. Did you find any of the 10 names to delete? Implement the Comparable interface on the Person class. Modify the Person class declaration to tell Java it will support the Comparable interface. Note this is parameterized" which means you need to put the object type in thebrackets just like you do for ArrayList. Note the red 'x' reminding you that you must now add the compareTo method to the Person class. You must exactly match the compareTo interface definition (function name, parameters, return type). Test only the email field and matclh the compareTo interface return type definition. Now, replace .equals with .compareTo in your nested loops written above for removed in the above step. o o Add a print statement "Total of>names after removals" and verify you removed 10 Persons and now only have 440 left. Add a print statement "Total of names after removals" and verify you removed 10 Persons and now only have 440 left. Add Names o Add another new call to readNames ("adds.csv"). Call this returned ArrayList "adds" Add a print statement "Read Total of adds" and verify you read 5 adds. Write another loop similar to removes. For each member to be added, check for an existing member with the same last name only, and add it immediately after that member. Note this is a different criterion than used for the removes. Make sure to only add each name once. Print a message if you can't find a name and include the email name you're adding. o o Print out "Total of names after adding" and verify it's 445. Sort Now that you have implemented Comparable you can sort the list without having to write almost anything. Write the code to use the Collections class to sort the ArrayList. o *Check your work Add a call from partA() to testPartA() to double check your work. This is similar to the types of tests Practicelt runs on your code. If you have errors use the debugger to see where the problem is exactly in your data and work backwards to fix. o o Check the total number of names is correct at each step o Check your compareTo is sorting based on email names Check you are not accidentally insert or removing more than once (there are names to trip you up if you should not take care of this) o Use intelligent variable names. Intelligently naming all your variables can make the difference between readable bug-free code and illegible broken code. By convention, classes should begin with Uppercase letters, while regular variables should begin with lowercase letters. . * return the firstName public String getFirstName() { return this.firstName; param firstName the firstName to set public void setFirstName(String firstName) { this. firstName = firstName ; * return the lastName public string getLastName() [ return this.lastName * @param lastName the lastName to set public void setLastName (String lastName) this.lastNamelastName; @return the email public String getEmail() return this.email; *@param email the email to set public void setEmail (String email) ( this.email - email; * Print out the name public string tostring) return "Person [firstName"this.firstName ", lastName-" this.lastName", email-"this.email + "]
