字符串转16进制字符串，16进制字符串转字符串

    

                                                      编程中偶尔会用到字符串与16进制的互转，废话不多说，直接上代码

   /**字符串转换为16进制字符串 **/
    public static String stringToHexString(String s) {
        char[] chars = "0123456789ABCDEF".toCharArray();
        StringBuilder sb = new StringBuilder("");
        byte[] bs = s.getBytes();
        int bit;
        for (int i = 0; i < bs.length; i++) {
            bit = (bs[i] & 0x0f0) >> 4;
            sb.append(chars[bit]);
            bit = bs[i] & 0x0f;
            sb.append(chars[bit]);
        }
        return sb.toString();
    }

    public static String hexString2String(String src) {
        String temp = "";
        for (int i = 0; i < src.length() / 2; i++) {
            temp = temp
                    + (char) Integer.valueOf(src.substring(i * 2, i * 2 + 2),
                    16).byteValue();
        }
        return temp;
    }
