Displaying unicode character in java shows "?" sign. For example, i tried to print "अ". Its unicode Number is U+0905 and html representation is "अ". The below codes prints "?" instead of unicode character.

char aa = '\u0905';
String myString = aa + " result" ;
System.out.println(myString); // displays "? result"

Is there a way to display unicode character directly from unicode itself without using unicode numbers? i.e "अ" is saved in file now display the file in jsp.

try to use utf8 character set - 

        Charset utf8 = Charset.forName("UTF-8");
        Charset def = Charset.defaultCharset();

        String charToPrint = "u0905";

        byte[] bytes = charToPrint.getBytes("UTF-8");
        String message = new String(bytes , def.name());

        PrintStream printStream = new PrintStream(System.out, true, utf8.name());
        printStream.println(message); // should print your character
