Which of the following is not a correct statement ?

Answer: The incorrect statement is "Abstract class can directly be initiated with ‘new’ operator."

Explanation:

• Every class containing abstract method must be declared abstract: True. If a class declares any abstract method, the class must be declared abstract (otherwise most compilers will report an error).

• Abstract class can directly be initiated with ‘new’ operator: False. You cannot instantiate an abstract class directly using new. You must define a concrete subclass that implements abstract methods and then instantiate that subclass.

• Abstract class can be initiated: This statement is ambiguous. An abstract class cannot be instantiated directly, but it can have constructors that run when a concrete subclass is created, so its behavior is available through subclass instances.

• Abstract class does not contain any definition of implementatio: Incorrect/poorly worded. Abstract classes can contain concrete (implemented) methods as well as abstract methods; they are not limited to only declarations.

Summary: The tested false statement is the claim that an abstract class can be instantiated directly with new. Remember that abstract classes cannot be directly instantiated; use a concrete subclass instead.
