String和Hex互相转换。 1.String转Hex,由于String元素本身就是数字,所以我们可以直接Format16进制。但是需要注意char是有符号的,所以我们需要转化为无符号的。whacr不需要转化 2.Hex转String。在转之前我们需要知道Hex是由wchar源转换的还是char转的。因为wchar占2个字节。而char一个字节。转换为对应的字符串的时候,wc...
当我们把string字符串转成byte[]后,要再转成string通过String.valueof()是实现不了的,只能newstring(byte[])..呵呵,我在使用java3des数据加密的时候,byte转string,存到文件,再取出string再转byte还是不对的,所以newstring(byte[])也不见得会得到正确结果的!! 最后我是采用byte转成16进制字符串,然后再将16进制...
StringeffectiveDateRes=newString(effectiveDateHexStr,0,16,StandardCharsets.US_ASCII); //比如0x8b73转为中文'王' //当8、b、7、3使用4个字节的ASCII分别存储传输时则需要先将底层串口通信数据转为string(“8b73”),再通过hexStringToByteArray转为byte[],再通过下面的方式转成中文 StringissuingAuthorityRes...
