java - switch 语句不切换

Question

我有一个值需要读取。该值是一个十六进制，我将其转换为整数。 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;
   }

这是输入为“A0”时的输出:

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

在每个最后一个内部 case 语句之后添加 break;
