导读：public interface Person { void introduce();} class Student implements Person { public Student() { // TODO Auto-generated constructor stub } introduce() { System.out.println( "我要去听课" ); }} class Teacher Teacher() { } @Override introduc
public interface Person { void introduce(); } class Student implements Person {
public Student() {
// TODO Auto-generated constructor stub
}
introduce() {
System.out.println("我要去听课");
}
}
class Teacher Teacher() {
}
@Override
introduce() {
TODO Auto-generated method stub
System.out.println("我要去讲课");
}
}
实现方法 class Introduce Person {
Person person;
Introduce() {
Introduce(Person person) {
this.person = person;
}
@Override
TODO Auto-generated method stub
System.out.println("大家好");
person.introduce();
}
}
主函数 class Test {
Test() {
static main(String[] args) {
TODO Auto-generated method stub
Student student = new Student();
Introduce sIntroduce = Introduce(student);
sIntroduce.introduce();
Teacher teacher = Teacher();
Introduce tIntroduce = Introduce(teacher);
tIntroduce.introduce();
}
}
运行结果 大家好
我要去听课
大家好
我要去讲课 （编辑：李大同） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
