我们做一个医院挂号排队小系统：患者根据需要选择相应的专家挂号排队等候，专家看完病人后通过点击按钮选择下一个患者。
其中包括患者，专家，患者客户端服务器，专家客户端服务器四个类。
患者类：
package com.dr.hospital;
public class Patient {
private String name;
private int num;
private int frontNum;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getNum() {
return num;
}
public void setNum(int num) {
this.num = num;
}
public int getFrontNum() {
return frontNum;
}
public void setFrontNum(int frontNum) {
this.frontNum = frontNum;
}
}
患者客户端服务器：
package com.dr.hospital;
import java.util.HashMap;
import java.util.LinkedList;
import java.util.Map;
import java.util.Queue;
public class QueueServer1 {
Map<Integer,Queue<Patient>> patientMap=new HashMap<Integer,Queue<Patient>>();
Queue<Patient> patientList1=new LinkedList<Patient>();
Queue<Patient> patientList2=new LinkedList<Patient>();
Queue<Patient> patientList3=new LinkedList<Patient>();
public Queue<Patient> init(Integer j) {
if(j==1){
for(int i=0;i<10;i++){
Patient p=new Patient();
p.setNum(i);
p.setFrontNum(i-1);
patientList1.offer(p);
patientMap.put(j, patientList1);
}
return patientList1;
}
else if(j==2){
for(int i=0;i<5;i++){
Patient p=new Patient();
p.setNum(i);
p.setFrontNum(i-1);
patientList2.offer(p);
patientMap.put(j, patientList2);
}
return patientList2;
}
else {
for(int i=0;i<3;i++){
Patient p=new Patient();
p.setNum(i);
p.setFrontNum(i-1);
patientList3.offer(p);
patientMap.put(j, patientList3);
}
return patientList3;
}
}
}
