java--组合类的实现
作者：互联网
何为组合类
一个类中含有另一个类
本程序为一个学生信息程序可访问老师的信息
好处：修改老师相关信息方便
package pac;
public class Combination1 {
String name;
String major;
String ID;
double GPA;
Professor teacher;
public Combination1(String na, String ma, String I, double J)
{
name = na;
major = ma;
ID = I;
GPA = J;
}
}
package pac;
public class Professor {
String name;
String course;
String email;
String phone;
public Professor(String na, String co, String em, String ph)
{
name =na;
course = co;
email = em;
phone = ph;
}
public void coursetime()
{
System.out.println("class table");
}
}
package pac;
public class Combanitiontest {
public static void main(String[] args) {
// TODO Auto-generated method stub
Combination1 student = new Combination1("liuwanqing", "software", "20206960",3.8);
Professor teacher1 = new Professor("teachertan", "lisanshuxue", "123@qq.com", "12345");
student.teacher = teacher1;
System.out.println(student.teacher.course);
student.teacher.coursetime();
}
}
坚持每天学一点，日更
生活充满迷茫，但只要坚持战斗，就没有输
