Which of the below statements are false about an abstract method?
A method without any body should be declared with abstract keyword explicitly, else compiler will throw an error.
If a class is having at least one abstract method, then that class should be declared as abstract class with explicit keyword abstract in the class level declaration.
A method with body also can be declared as abstract method.
A class can be declared as abstract even if that class doesn't have any abstract methods.
If a method is having function body, then it is wrong to declare it as abstract method. But a class can be declared as abstract even if it doesn't have any abstract methods.
