No, you can never instantiate an abstract class.

You cannot directly instantiate an abstract class. However, you can instantiate a concrete subclass and upcast the reference to the abstract type. For example...

abstract class AbstractClass {}
 
class Concrete extends AbstractClass {}
 
class TestAbs {
  public static void main(String[] args) {
    //AbstractClass a1 = new AbstractClass(); //ERROR
    AbstractClass a2 = new Concrete(); //OK
  }
}
