Challenge Problems

Push your limits with challenges.

Question 1

Design a Java class structure using inheritance to represent shapes. Include at least one subclass for a geometric shape and demonstrate method overriding.

💡 Hint: Think about how different shapes will have different ways to calculate their area, and implement that in code.

Question 2

Implement multiple interfaces in a Java class. Create interfaces for 'Draw' and 'Paint', and have a class 'Art' that implements both.

💡 Hint: Consider how a single class can adopt behaviors from multiple interfaces.
