Parsing a List of Pojos

Question

Hello Java experts,
A questions for you regarding pojos in a List.
I have a pojo called 'Role' which has 2 instance variables - int Count and String RoleType. I have a List of Roles, which I want to parse to find out if a particular RoleType is present in my list.
List<Roles> roleList = new ArrayList<Roles>();
What method if any can I use to find out if the RoleType, say 'Admin' is present in my roleList? If this was a List<String> I could have used the contains() or indexOf() method to do this. I am stumped as it is a list of pojos.
Any ideas will be much appreciated!
Thanks in advance.

Assuming you created your "POJO", just add something like the following to your class
public boolean isAdmin() {
        return roleType.equals("Admin");
}When you are in the loop, just call myPojo.isAdmin().
This is just an idea, you might have change variable names based on your class.
