Java 如何把gb2312编码转化为汉字

public void testApp() throws Exception
{
    String string = "C2ACD0E3cbd5343232373234313836323230323033313833";
    String result = stringToGbk(string);
    System.out.println(result);
}
//将gbk编码转换成汉字
public  String stringToGbk(String string) throws Exception
{
    byte[] bytes = new byte[string.length() / 2];
    for(int i = 0; i < bytes.length; i ++){
        byte high = Byte.parseByte(string.substring(i * 2, i * 2 + 1), 16);
        byte low = Byte.parseByte(string.substring(i * 2 + 1, i * 2 + 2), 16);
        bytes[i] = (byte) (high << 4 | low);
    }
    String result = new String(bytes, "gbk");
    return result;
}
