The array generator expression yields all components of an array as its results.

The type of an array generator expression is the component type of the type of the subexpression. It is a compile-time error if the latter type is not an array type.

The array generator expression is a generator expression. Its sequential evaluation evaluates the subexpression. If the result is null, a NullPointerException is thrown. Otherwise, all components of the resulting array are yielded as variables in ascending order of indices.
