Java 接口实现飞行功能：鸟类和昆虫类示例

public interface Flyable {void fly();}public class Bird {private String name;public Bird(String name) {this.name = name;}public void printInfo() {System.out.println("我是" + name + "，我有2只腿，我可以生蛋，我可以飞");}}public class Insect {private String name;private int legCount;public Insect(String name, int legCount) {this.name = name;this.legCount = legCount;}public void printInfo() {System.out.println("我是" + name + "，我有" + legCount + "只腿，我可以产卵，我可以飞");}}public class Main {public static void main(String[] args) {Bird pigeon = new Bird("鸽子");pigeon.printInfo();Bird goose = new Bird("大雁");goose.printInfo();Insect ant = new Insect("蚂蚁", 6);ant.printInfo();Insect bee = new Insect("蜜蜂", 6);bee.printInfo();}}
