Interfaces are needed in programming to define a contract or set of methods that a class must implement. This allows for a level of abstraction and flexibility in the code, as different classes can implement the same interface in their own way. Interfaces also help in achieving loose coupling between different components of a system, making it easier to maintain and extend the codebase. Overall, interfaces promote code reusability, modularity, and help in enforcing a consistent structure in object-oriented design. **
