How do I replace the following array with an ArrayList.
Employee[] companyTeam = {manager, engineer1, superviso1, accountant, intern };

You can do something like
List<Employee> companyTeam = Arrays.asList(manager, engineer1, superviso1, accountant, intern);

Arrays.asList(companyTeam) in case you already have an array..

the word "Arrays" and "List" is highlighted in red. Any idea why?

You need to import them. Add
import java.util.List; and import java.util.Arrays; to the top of your file. Or if you're using Eclipse ctrl + shift + O will import them for you.Sameena
Hi Mike, that works. Thanks. But if Im only to use the import java.util.ArrayList command. How would I go about writing the code for it? I tried using ArrayList<Employee> companyTeam = {manager, engineer1, superviso1, accountant, intern};but then im getting an "illegal initializer for for ArrayList error"

You can do
ArrayList<Employee> companyTeam = new ArrayList<Employee>(Arrays.asList(manager, engineer1, superviso1, accountant, intern)); Employee[] companyTeam = {manager, engineer1, superviso1, accountant, intern };
List<Employee> list=Arrays.asList(companyTeam);// array to List
You already have an array, So you can use Arrays.asList(companyTeam) to convert array to List

java.util.ArrayListcheck the duplicate question (above). FYI,Arrays.asListreally returns anArrays.ArrayList, although that might not matter.
