java编程 定义一个接口Person，声明相关的属性和方法，再用Teacher类和Student
public interface Person{ public String name; public int age; public Person(String name, int age);}public class Teacher implements Person{ public Teacher(String name, int age){ super(name, age); } public String toString(){ return String.format("Teacher[name=%s, age=%d]", name, age); }}public class Student implements Person{ public Student (String name, int age){ super(name, age); } public String toString(){ return String.format("Student[name=%s, age=%d]", name, age); }}public class Main{ public static void main(String[] args){ for(int i = 0; i < 10; i++){ Person t = new Teacher("t" + i, i); Person s = new Student("s" + i, i); System.out.println(t); System.out.println(s); } }}
给你写了一个，不知道能不能帮到你。

连城县15521198980： java中返回类型为接口?怎么返回? - ？
关易希美： 返回类型为一个接口的方法的话,可以用接口的类型作为返回值,也可以用实现了这个接口的类作为返回类型,比如你在一个person类中定义了一个方法:public List<?> say(){}; 那么下面调用此方法的时候可以用 List<?> list = new person().say(); 或者用 ArrayList<?> arr = new person().say().
连城县15521198980： Java关于接口引用子类对象？
关易希美： 在你这里是完全一样的, 其实有很多人认为java的接口是多此一举,没有必要的 java的接口只是为了实现“多继承”和制作java的标准用的,例: 我自己写了一套X软件,里面有A,B两个类,但是A,B是为了满足1,2这两种不同的用户使用的,...

连城县15521198980： java中接口的功能及其定义格式 - ？
关易希美： 接口定义为 public interface 接口名称{}接口的作用是基于面向对象思想的,给你举个例子: 例如,我们有一个男人实现了“人”接口,“人”接口中有走路的方法,现在男人实现了“走路”方法,这时候,如果有个需求,要把男人换为女人,这时候只要换做女人类,并且女人类实现了“走路”方法,用女人类替换掉男人类即可. 这样的好处就是,接口没有变,也就是设计中的接口没有变,只是实现类的变化,最大程度的减少了需求变化对代码的影响. 希望对楼主有帮助,如果还有不明白的地方,请留言.
