ArrayList Retrieve object by Id

Question

Suppose I have an ArrayList of my custom Objects which is very simple. For example:

class Account
{
public String Name;
public In         


        

Answer 1

A better way to do this would be to use a Map.

In your case, you could implement it in the following way

    Map

you can use the "get" method to retrieve the appropriate account object.

    accountMap.get(id);
