		Console.WriteLine(Char.GetUnicodeCategory(ch2));		// Output: "DecimalDigitNumber"
		Console.WriteLine(Char.GetUnicodeCategory(str, 6));		// Output: "UppercaseLetter"
	}
}

import System.*;

public class GetUnicodeCategorySample
{
    public static void main(String[] args)
    {
        char ch2 = '2';
        String str = "Upper Case";
