public class student1 {
protected String name;
protected int classid;
protected int id;
public student1(String str,int n,int m)
{
name=str;classid=n;id=m;
}
public void move()
{
System.out.println("上课，学习");
}
public void display()
{
System.out.println("姓名"+name+" "+"班级"+classid+" "+"学号"+id);
}
}
public class teacher extends student1{
protected int tid;
protected int salary;
public teacher(String str,int k,int s,int n,int m)
{
super(str,k,s);
tid=n;salary=m;
}
public void tmove()
{
System.out.println("批改作业，备课，上课");
}
void tdisplay()
{
System.out.println("工号"+tid+" "+"工资"+salary);
}
public static void main(String [] args)
{
teacher m=new teacher("asd",5,001,0065,8000);
m.move();
m.tmove();
m.display();
m.tdisplay();
}
}
二.使用super来引用父类构造函数
三，例题
