How do i replace an array with an arraylist?

Question

How do I replace the following array with an ArrayList.

Employee[] companyTeam = {manager, engineer1, superviso1, accountant, intern };

If you really need a `java.util.ArrayList` check the duplicate question (above). FYI, `Arrays.asList` *really* returns an `Arrays.ArrayList`, although that might not matter. — Jonathan, Jan 23 '14 at 14:50

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.. – TheLostMind Jan 23 '14 at 14:43
the word "Arrays" and "List" is highlighted in red. Any idea why? – Sameena Jan 23 '14 at 14:51
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. – Mike B Jan 23 '14 at 14:57
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 companyTeam = {manager, engineer1, superviso1, accountant, intern};but then im getting an "illegal initializer for for ArrayList error" – Sameena Jan 23 '14 at 15:16
You can do `ArrayList companyTeam = new ArrayList(Arrays.asList(manager, engineer1, superviso1, accountant, intern));` – Mike B Jan 23 '14 at 15:29

 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
