Yes, but it is not recommended to create an instance
directly for abstract class, it may causes to crash the JVM.

First one thing you want to know is Abstraction. Hiding
unnecessary details to the user and expose the details which
are required to the end user is called abstraction.

Eg: In telephone, dialing a number is an interface and
complex circuit which takes keystrokes of a user and
performs the necessary operation is called it's implementation.

Generally, humans manage complexity through abstraction.
So any complex device can be operated by abstraction, even
though they don't know it's implementation.

Abstract class contains abstract methods and concrete
methods. A method without body is called abstract method
otherwise it 'll be treated as general method.

Solution:
If you want to create an instance for abstract class,
first you create a concrete subclass and create an instance
for that and use it.
