Create a Statically Initialized List of Objects

A group of objects can be organized into arrays or collections. Arrays are nice because you can statically initialize them, but collections have far more functionality. Using this tip you can have your array and iterate it too!

In your class, create your statically initialized array as always:


    public static String [] primeColorsArray = { "red", "blue", "green" };
And on the next line create a List, using the Arrays.asList() method to convert the static array.
    public static List primeColorsList = Arrays.asList(primeColorsArray);
Voila!

The result is more concise and elegant that calling the List.add() method over and over again.
