why java doesn't support cyclic pls explain me with example
Answer Posted / kaustav chatterjee
Every class in java by default extends the Object class and they have to cause java is almost an object oriented language.but if we take this scenario where class B extends class A and class A extends class B then as java don't support multiple inheritance or multiple super class then class A cannot extend the Object class and cannot be a Object type or subclass of Object class but by definition of JAVA every class is a subclass of Object class.Hence it's not supported by JAVA as it contradicts basic definition of JAVA.
but if we don't extending any class in class A then it by default extends Object class and class B by extending class A also extending Object class.so there is no problem.
