一個案子通常都會定義一些Constants也就是"常數"來共用
而裡頭通常也會包含enum 類別
XXXConstants.java:
public class XXXConstants {
//系統Y與N
public static String YES = "Y";
public static String NO = "N";
// 0啟用,1停用,2已售完
public static enum ORDER_STATUS{
啟用,停用,已售完,其它
}
public static String AAML_STATUS_SEND = "0"; //0已建立
public static String AAML_STATUS_SEND_SUCCESS = "1"; //1傳送成功
}
test_main.java:
import cc.openhome.web.XXXConstants.ORDER_STATUS;
public class test_main {
public static void main(String[] args) throws Exception {
ORDER_STATUS b = findOrderStatus(4);
System.out.println(b); // output: 其它
ORDER_STATUS a = findOrderStatus(0);
System.out.println(a); // output: 啟用
ORDER_STATUS c = findOrderStatus(1);
System.out.println(c); // output: 停用
}
public static ORDER_STATUS findOrderStatus(int intType){
ORDER_STATUS rtn = null;
try{
rtn = ORDER_STATUS.values()[intType];
}catch(Exception e)
{
rtn = ORDER_STATUS.其它;
}
return rtn;
}
}
