How can I remove duplicate Objects from array of Objects in javascript?

Java, storing objects in array?

• i have a class Person which creates Person-objects, and i need to store these objects in an array located in another class Payroll. also need methods to add and remove Persons from this array. how do i do this?

• Answer:

  private List<Person> people = new ArrayList<Person>(); public void addPerson(Person person) { people.add(person); } public Person removePerson(Person person) { Person p = null; int idx = people.indexOf(person) if (idx != -1) { Person p = people.remove(idx); } return p; } Or something along those lines depending on how you want to remove the person from the array. Of course, you could make removePerson a void method if you don't care about getting back the object you are removing from the array. Also, if you are going to be doing a lot of adding and removing, a LinkedList might be more efficient than an ArrayList. It has the same interface though, so the code above is the same except you change ArrayList to LinkedList.
