Question

在我的程序中，我得到一个十六进制格式的字符串。我想将其转换为字符串。怎么做？

谢谢和问候。帕尔瓦蒂

Answer 1

使用以下代码将十六进制转换为字符串

String hexadecimalnumber = "00000011";
    BigInteger big = new BigInteger(hexadecimalnumber);
    String requiredString = big.toString(16);
    System.out.println("...data..."+requiredString);

Answer 2

String hex = "ff";
hex = Integer.toString(Integer.parseInt(hex, 16));

Answer 3

class Test 
{
    private static int hextoint(char c) {
        if (c >= '0' && c <= '9') {
            return c - '0';
        }
        if (c >= 'a' && c <= 'f') {
            return c - 'a' + 10;
        }
        if (c >= 'A' && c <= 'F') {
            return c - 'A' + 10;
        }
        return -1;
    }

    private static String hexdec(String str) {
        int len = str.length();
        if(len % 2 != 0){
            return null;
        }
        byte[] buf = new byte[len/2];
        int size = 0;
        for (int i = 0; i < len; i += 2) {
            char c1 = str.charAt(i);
            char c2 = str.charAt(i + 1);
            int b = (hextoint(c1) << 4) + hextoint(c2);
            buf[size++] = (byte)b;
        }

        return new String(buf, 0, size);
    }

    public static void main(String[] args) 
    {
        String str = "616263";
        String out = hexdec(str);
        System.out.println(out);
    }
}
