校园自习教室预定系统

校园自习室管理系统设计如下：
1、初步设计：
package xz;
import java.util.Scanner;
public class Diyici {

public static void syslogin(){
	System.out.println("登录系统...");
}

public static void modifyInfo(){
	System.out.println("修改个人信息...");
}

public static void queryClassroom(){
	System.out.println("查询自习教室...");
}

public static void orderClassroom(){
	System.out.println("预订自习教室...");
}

public static void main(String[] args){
	Scanner reader=new Scanner(System.in);
	int break_flag=0;
	while(true){
		System.out.println("请输入：1.登录系统  2.修改个人信息  3. 查询自习教室  "
				+ "4. 预定自习教室   0.退出");
		int choice=reader.nextInt();
		switch(choice){
		case 1:
			syslogin();break;
		case 2:
			modifyInfo();break;
		case 3:
			queryClassroom();break;
		case 4:
			orderClassroom();break;
		case 0:
			break_flag=1;break;
		}
		System.out.println(" ");
		if(break_flag==1)
			break;
		
	}
	System.out.println("退出系统...");
	reader.close();
}

}

2、初步计划运行效果：

3、学生信息系统：
package xz;
public class Zixi {
private String number;
private String name;
private String stex;
private String spc;
public Zixi(){
}
public Zixi(String number,String name, String stex, String spc)
{ super();
this.number = number;
this.name = name;
this.stex = stex;
this.spc = spc;
}
public String getName() { return name; }
public void setName(String name) { this.name = name; }
public String getStex() { return stex; }
public void setStex(String stex) { this.stex = stex; }
public String getAge() { return spc; }
public void setAge(String age) { this.spc = spc; }
public String getNumber() { return number; }
public void setNumber(String number) { this.number = number;
}
}
