Solution 2

An abstract class cannot be instantiated, and that's why new doesn't work.

Solution 3

No. Abstract classes cannot be instantiated, which means they cannot appear on the right hand side of a new operator.
You can however derive y from x by using the extends keyword and it will get the content that way.
