    Default 2 Method Problem

    I'm trying to modify my list by updating it and finding the last name. How can I rewrite my last 2 methods to do that.




    import java.util.ArrayList;

    public class DataCollection {

    ArrayList<Person> list = new ArrayList<>();



    Person newName = new Person(10,"aas","gym","798",876-123);



    Person p1 = new Person(11,"aaa", "gina","654",911-911);
    Person p2 = new Person(12, "persia","weee","546",324);


    public void add(Person person) {
    list.add(person);
    }

    public int remove(String lastName) {
    for (int i = 0; i < list.size(); i++) {
    Person person = list.get(i);
    if (person.getLastName().equals(lastName)) {
    list.remove(person);
    }
    }

    public int update(String lastName, String newName){
    Person person;
    for (int i = 0; i < list.size(); i++) {
    person = list.get(i);
    if (person.lastName != person.){
    Person.setLastName(newName);


    }
    public Person find (String lastName){
    Person person;
    for (int i = 0; i < list.size(); i++) {
    person = list.get(i);
    if (person.lastName.equals(lastName)) {
    System.out.print(lastName);
    }
    }
    }
    }
    }
    }
    }

    Default Re: 2 Method Problem

    modify my list by updating it and finding the last name.
    What problems are you having with the posted code?
    Copy and paste here the full text of any error messages/
    If the results are not what you want, show the current results and explain what you want in place of that.

    Please edit your post and wrap your code with code tags:

    [code]
    **YOUR CODE GOES HERE**
    [/code]

    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.
