JAVA编程请定义一个寝室类,内容自拟!

寝室类如下：

寝室中住宿的人员类如下：

import java.util.Objects;

public class Person {

public String getSno() {

return sno;

}

public void setSno(String sno) {

this.sno = sno;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public String getSubject() {

return subject;

}

public void setSubject(String subject) {

this.subject = subject;

}

@Override

public boolean equals(Object o) {

if (this == o) return true;

if (o == null || getClass() != o.getClass()) return false;

Person person = (Person) o;

return Objects.equals(sno, person.sno)

Objects.equals(name, person.name)

Objects.equals(subject, person.subject);

}

@Override

public int hashCode() {

return Objects.hash(sno, name, subject);

}

@Override

public String toString() {

return "Person{" +

"sno='" + sno + '\'' +

", name='" + name + '\'' +

为宿舍管理人员编写一个宿舍管理查询软件, 程序采用交互工作方式,

基本上就是这样了。。。只有输出输入用了c++的cout/cin你可以自己换成printf和scanf，很简单的。。

程序在vc下运行了。

java语言编写的学生宿舍管理系统

也不是难啊！关键是麻烦啊！你看看你要的差不多就一个项目了啊！还要建表啊！用数据库啊！我这有一个图书管理系统啊！是jcreat做的啊！你那个就是实现了增删改差啊！基本功能，不过麻烦啊！你要是局部的不是先帮助还行啊！
