Help: About coding

For example, now there is a "test" word. Its UNICODE ASCII code is 27979. Hexadecimal ASCII code is 6D4B.

Now I want to convert it to GBK internal code, that is, to get the GBK ASCII code of "test" word: 45794, and then I convert it to hexadecimal. . . I ask everyone how to get the ASCII code of the GBK internal code of Chinese characters?

Thank you

char a = 'Measure';
System.out.println (Integer.toHexString (((int) a)));
System.out.println ((int) a);
byte [] b = new String ("测") .getBytes ("gbk");
int i = b [1] << 4;
i = i | b [0];
a = (char) i;
System.out.println (Integer.toHexString (((int) a)));
System.out.println ((int) a);

Slow a beat,
When String.getBytes seems to throw UnsupportedEncodingException.

It's impossible, brother

Ha ha, I do n’t think it is right

Rewritten

        public static String getGBK (String a) throws UnsupportedEncodingException {
    byte [] b = new String (a) .getBytes ("gbk");
    String b1 = Integer.toString ((char) b [0], 16) .toUpperCase ();
    String b2 = Integer.toString ((char) b [1], 16) .toUpperCase ();
    return b1.substring (2,4) + b2.substring (2, 4);
     }
     public static int getGBKINT (String a) throws UnsupportedEncodingException {
    String tmp = getGBK (a);
    return Integer.parseInt (tmp, 16);
     }

test
String a = "测";
System.out.println (getGBK (a));
System.out.println (getGBKINT (a));

I finally realized that my first wording was wrong, and the number of digits and high status were wrong.
                  char aa = 'Measure';
byte [] b = new String ("Test"). getBytes ("gbk");
int high = b [0] << 8&0xFFFFFF00;
int low = b [1]&0xFFFF00FF;
int gbk = (high | low)&0x0000FFFF;
System.out.println (Integer.toHexString ((gbk)));
System.out.println (gbk);

char aa = 'Measure';
byte [] b = new String ("Test"). getBytes ("gbk");
int high = b [0] << 8&0xFFFFFF00;
int low = b [1]&0xFFFF00FF;
int gbk = (high | low)&0x0000FFFF;
System.out.println (Integer.toHexString ((gbk)));
System.out.println (gbk);

Conversely, decoding is not that simple. .

Yes, the getbyte function is actually very powerful
But the converse is also the same, mainly need to check the information, check the area corresponding to unicode and gbk
