Java字符串的GBK编码程序问题
/*中国两个字符串的GBK编码为“D6D0B9FA”,
在下面程序(1)与（2）处应该怎样写
才能打印出中国*/
求高手帮忙解决此问题
public static void main(String[] args) throws UnsupportedEncodingException{
/*中国两个字符串的GBK编码“D6D0B9FA”,
怎样拼接出中国*/
char[] num={'0','1','2','3','4','5','6','7','8','9','A','B','C','D','E','F'};
String code="中国";
byte[] bytes=code.getBytes("GBK");
StringBuffer buf=new StringBuffer();
for (int i = 0; i < bytes.length; i++) {
byte b=bytes[i];
byte r=（1）;
byte h=（2）;
buf.append(num[h]);
buf.append(num[r]);
}
System.out.println("==汉字===="+buf);
} 编码 java stringbuffer GBK编码
