How to check the double byte character fall in 'A'..'Z' and 0..9?

Can you provide a little more information. If you want to know whether or not a character falls within a specific range, the following code will work:

char c;

// read your character

if (c >= '\uFF21' && c <= '\uFF3a') {

// do something

}

Since Java uses Unicode (UCS2) internally, there is no difference in treatment between so called double byte characters or any other character.
