The Athlete interface is an interface with some actions of an athlete: public interface Athlete { void compete(); void swim(); void highJump(); void longJump(); } We have added the method compete, but also there are some extra methods like swim, highJump, and longJump. Suppose that John Doe is a swimming athlete. By implementing the Athlete interface, we have to implement methods like highJump and longJump, which John Doe will never use. public class John Doe implements Athlete { @Override public void compete() { System.out.println("John Doe started competing"); } @Override public void swim() { System.out.println("John Doe started swimming"); } @Override public void highJump() { } @Override public void longlump() { } Which principle is violated in this approach? S - Single-responsibility principle. 0 - Open-closed principle. L - Liskov substitution principle. 1 - Interface segregation principle. D - Dependency Inversion Principle
