*/
public static final int LOG_IN=1;
public static final int LOG_OUT=0;
public static final String LogTypeArray[]=new String[]{
"LogOut",
"LogIn"
};
public LogRec(int id, Date time, String address, int type, String user, String ip, int logType) {
super(id, time, address, type);
this.user = user;
this.ip = ip;
this.logType = logType;
}
public String getUser() {
return user;
}
public void setUser(String user) {
this.user = user;
}
public String getIp() {
return ip;
}
public void setIp(String ip) {
this.ip = ip;
}
public int getLogType() {
return logType;
}
public void setLogType(int logType) {
this.logType = logType;
}
@Override
public String toString() {
return "LogRec: " +
super.toString() +
"\nuser=" + user +
"\nip=" + ip +
"\nlogType=" + LogTypeArray[logType] +
"\n";
}
public char[] toArray() {
String data = this.getId() + "," + this.getTime().getTime() + "," + this.getAddress() + "," + this.getType() + "," + this.getUser() + "," + this.getIp() + "," + LogTypeArray[this.getLogType()];
return data.toCharArray();
}
}

super.toString() +
"\nhandler=" + handler +
"\nreciver=" + reciver +
"\ntransportType=" + TransportArray[transportType] +
"\n";
}
public char[] toArray() {
String data = this.getId() + "," + this.getTime().getTime() + "," + this.getAddress() + "," + this.getType() + "," + this.getHandler() + "," + this.getReciver() + "," + TransportArray[this.getTransportType()];
return data.toCharArray();
}
}
【任务5.2.3】创建物流、日志测试类，测试任务5.2中的程序，演示物流信息、日志信息的采集及打印输出
在com.qst.dms.dos 下创建EntityDataDemo.java
功能要求：采集2组物流信息、2组日志信息，放到数组中，再打印输出
程序设计
package com.qst.dms.dos;
import com.qst.dms.entity.LogRec;
import com.qst.dms.entity.Transport;
import com.qst.dms.service.LogRecService;
import com.qst.dms.service.TransportService;
public class EntityDataDemo {
public static void main(String[] args) {
LogRecService logRecService = new LogRecService();
TransportService transportService = new TransportService();
// 采集日志信息
LogRec logRec1 = logRecService.inputLog();
LogRec logRec2 = logRecService.inputLog();
// 放到数组中
LogRec[] logRecArray = {
logRec1, logRec2};
// 打印输出
logRecService.showLog(logRecArray);
// 采集物流信息
Transport transport1 = transportService.inputTransport();
Transport transport2 = transportService.inputTransport();
// 放到数组中
Transport[] transportArray = {
transport1, transport2};
// 打印输出
transportService.showTransport(transportArray);
}
}
测试：
要求全部可能情况都要测一遍
存在哪些可能的bug及修复?
当输入非法字符时会报错，可以添加异常处理，提示用户重新输入。
