Utility method for wrapping an object in a collection

Question

I\'m looking for a static method in the Java core libraries or some other commonly used dependency — preferably one of Apache — that does the following:

public s         


        

Answer 1

Immutable list in guava

public static  ImmutableList of(E element)

Returns an immutable list containing a single element. This list behaves and performs comparably to Collections.singleton(T), but will not accept a null element. It is preferable mainly for consistency and maintainability of your code.
