16进制字符串转字节数组

直接上代码&＃xff1a;

public static void main(String[] args) {String str&＃61;"23555555550b01010000D002002A";byte[] d &＃61;hexStringToBytes(str);printHexString(d);}/** * 16进制字符串转byte[] * &＃64;param hexString the hex string * &＃64;return byte[] */ public static byte[] hexStringToBytes(String hexString) { if (hexString &＃61;&＃61; null || hexString.equals("")) { return null; } hexString &＃61; hexString.toUpperCase(); int length &＃61; hexString.length() / 2; char[] hexChars &＃61; hexString.toCharArray(); byte[] d &＃61; new byte[length]; for (int i &＃61; 0; i

效果&＃xff1a;
