package StartDiaguo;import java.io.Serializable;//import java.util.*;public class Appointment implements Serializable { private String clientName; private String startTime; private String endTime; private String date; private Appointment next; public Appointment(){ clientName = null; date = null; startTime = null; endTime = null; next = null; } public Appointment(String name,String d, String s, String e){ clientName = name; date = d; startTime = s; endTime = e; next = null; } public Appointment getNext(){ return next; } public void setNext(Appointment ap){ next = ap; } public String getName(){ return clientName; } public void setName(String name){ clientName = name; } public String getTime(){ return startTime +"-"+ endTime; } public void setTime(String s, String e){ startTime = s; endTime = e; } public String getStartTime(){ return startTime; } public void setStartTime(String s){ startTime = s; } public void setEndTime(String e){ endTime = e; } public String getEndTime(){ return endTime; } public String getDate(){ return date; } public void setDate(String d){ date = d; } public void setAppointment(String n, String d, String s, String e) { clientName = n; startTime = s; endTime = e; date = d; }}private Map<String, Appointment> appBook; 来存一个Appointment
Appointment 是一个linkedlist的形式
我用hashmap来存这个自定linkedlist类，当我想改Appointment.next 的内容后 怎么返回第一个app
还是有什么办法更改hashmap的key
------解决方案--------------------
这是我提供的 管理约会的一个解决方案，一组有序列的约会抽象为AppSeries，那里面提供了对约会事件的基本增加和删除操作
对于你关注的一次约会序列当中 找一次约会的下一次约会，可以通过查找对应的index然后index+1再通过AppSeries调用提供的API实现，下面的TestApp有演示
