Understanding the Difference between Abstract Class and Interface in OOPS

In OOPS, the main difference between an abstract class and an interface lies in their purpose and structure.

Abstract Class:

• Contains both abstract and concrete methods.
• Can have data members.
• Allows method implementation within the class.

Interface:

• Contains only method signatures without any implementation.
• Cannot have data members.
• Requires implementing classes to define the methods.

When to use abstract classes vs. interfaces depends on the design requirements of the program.
