Question

我有一个需要阅读的值。该值是我转换为int的十六进制。我有几个可能的值，但switch语句接受所有情况。

 int messValue = Integer.parseInt(messType,16);
   switch(messValue)
   { 
   case 160 : System.out.println(messType.toUpperCase() + " It's a financial Message request");
   case 161 : System.out.println(messType.toUpperCase() + " It's a financial Message  response");
   case 162 : System.out.println(messType.toUpperCase() + " It's a Reversal message request");
   case 163 : System.out.println(messType.toUpperCase() + " It's a Reversal message Acquirer Repeat");
   case 164 : System.out.println(messType.toUpperCase() + " It's a Reversal message response");
   case 165 : System.out.println(messType.toUpperCase() + " It's a Network message request");
   case 166 : System.out.println(messType.toUpperCase() + " It's a Network message response");
   case 167 : System.out.println(messType.toUpperCase() + " It's a Network message response issuer");
   default : break;
   }

输入为＆＃34; A0＆＃34; ：

A0 It's a financial Message request
A0 It's a financial Message  response
A0 It's a Reversal message request
A0 It's a Reversal message Acquirer Repeat
A0 It's a Reversal message response
A0 It's a Network message request
A0 It's a Network message response
A0 It's a Network message response issuer
