裁判测试程序样例中展示的是一段定义基类People
、派生类Student
以及测试两个类的相关Java代码,其中缺失了部分代码,请补充完整,以保证测试程序正常运行。
函数接口定义:
提示: 观察派生类代码和main方法中的测试代码,补全缺失的代码。
裁判测试程序样例:
注意:真正的测试程序中使用的数据可能与样例测试程序中不同,但仅按照样例中的格式调用相关方法(函数)。
class People{
protected String id;
protected String name;
/** 你提交的代码将被嵌在这里(替换此行) **/
}
class Student extends People{
protected String sid;
protected int score;
public Student() {
name = "Pintia Student";
}
public Student(String id, String name, String sid, int score) {
super(id, name);
this.sid = sid;
this.score = score;
}
public void say() {
System.out.println("I'm a student. My name is " + this.name + ".");
}
}
public class Main {
public static void main(String[] args) {
Student zs = new Student();
zs.setId("370211X");
zs.setName("Zhang San");
zs.say();
System.out.println(zs.getId() + " , " + zs.getName());
Student ls = new Student("330106","Li Si","20183001007",98);
ls.say();
System.out.println(ls.getId() + " : " + ls.getName());
People ww = new Student();
ww.setName("Wang Wu");
ww.say();
People zl = new People("370202", "Zhao Liu");
zl.say();
}
}
在这里给出一组输入。例如:
(无)
输出样例:
在这里给出相应的输出。例如:
I'm a student. My name is Zhang San.
370211X , Zhang San
I'm a student. My name is Li Si.
330106 : Li Si
I'm a student. My name is Wang Wu.
I'm a person! My name is Zhao Liu.
