有關排隊系統的應用是很多的，本文是針對醫院的排隊掛號流程進行的簡易設計。要設計排隊系統，首先要分別設計出病人和專家的類，然后編寫服務器類模擬出若干等侯的病人。最后分別編寫出專家與病人的客戶端。具體步驟及代碼如下：
1.病人類。
package com.TinySK;
public class Pro {
private int proId;
private String proName;
private Patient patienter;
public Pro(Patient patienter){
this.patienter=patienter;
}
public int getProId() {
return proId;
}
public void setProId(int proId) {
this.proId = proId;
}
public String getProName() {
return proName;
}
public void setProName(String proName) {
this.proName = proName;
}
public Patient getPatienter() {
return patienter;
}
public void setPatienter(Patient patienter) {
this.patienter = patienter;
}
}
2.專家類。
package com.TinySK;
public class Pro {
private int proId;
private String proName;
private Patient patienter;
public Pro(Patient patienter){
this.patienter=patienter;
}
public int getProId() {
return proId;
}
public void setProId(int proId) {
this.proId = proId;
}
public String getProName() {
return proName;
}
public void setProName(String proName) {
this.proName = proName;
}
public Patient getPatienter() {
return patienter;
}
public void setPatienter(Patient patienter) {
this.patienter = patienter;
}
}
3.服務器端。
package com.TinySK;
import java.util.HashMap;
import java.util.LinkedList;
import java.util.Map;
import java.util.Queue;
public class PatientServer {
private static int num=1;
public static int getNum() {
return num;
}
public static void setNum(int num) {
PatientServer.num = num;
}
Map<String,Queue<Patient>> per=new HashMap<String,Queue<Patient>>();
LinkedList<Patient> waiterList1 = new LinkedList<Patient>();
LinkedList<Patient> waiterList2 = new LinkedList<Patient>();
LinkedList<Patient> waiterList3 = new LinkedList<Patient>();
public Map<String,Queue<Patient>> init(){
for(int i=1;i<=30;i++,num++){
Patient w1 = new Patient();
w1.setId(num);
w1.setFormer(i-1);
waiterList1.offer(w1);
}
per.put("馮醫生",waiterList1);
for(int i=1;i<=20;i++,num++){
Patient w2 = new Patient();
w2.setId(num);
w2.setFormer(i-1);
waiterList2.offer(w2);
}
per.put("王醫生",waiterList2);
for(int i=1;i<=10;i++,num++){
Patient w3 = new Patient();
w3.setId(num);
w3.setFormer(i-1);
waiterList3.offer(w3);
}
per.put("閆醫生",waiterList3);
return per;
}
}

有關醫院排隊系統的簡易模型就此完成，對于界面的美化，不再過多介紹。還有對于服務器端的模擬不太真實，這部分在實際應用中會很重要，而且要占一大部分內容，本文只是簡單的模擬了一下服務器端。有關服務器端與用戶端的結合使用，將在以后分析。本文寫的不是很完善，若有問題請批評指正。
