6 String intValue2 = Integer.toHexString(bytes[index] & 0xF);7 result.append(invalue1);8 result.append(intValue2);9 } 10return result.toString();11 } 然后介绍⼀种更实⽤的字符串和⼗六进制之间的转换:⼗六进制转字符串:
String hex= Integer.toHexString(b & 0xFF);if(hex.length() < 2){ hex= "0" +hex; }returnhex; } 很多时候,我们需要转换的是一个byte数组,一个一个byte调用上面的方法显然太麻烦。 /*** 字节数组转16进制 *@parambytes 需要转换的byte数组 ...
方法如下:/ Convert byte[] to hex string.这里我们可以将byte转换成int,然后利用Integer.toHexString(int)来转换成16进制字符串。param src byte[] data return hex string / public static String bytesToHexString(byte[] src){ StringBuilder stringBuilder = new StringBuilder("");if (src == ...
