根据下表(出自Table 2.11.1-A. Type support in the Java Virtual Machine instruction set),可以发现大部分指令都没有支持 byte、char 和 short 类型,甚至没有任何指令支持 boolean 类型。因此如果要对两个 short 类型的数字相加,那只能转成 int,再使用 iadd 命令相加,然后再转成 short 了。 基本类型有多大?

For example, suppose the value of Type is HEADER and the value of Data is User-Agent. If you want to search the User-Agent header for the value BadBot, you base64-encode BadBot using MIME base64-encoding and include the resulting value, QmFkQm90, in the value of SearchString. If...
