回答1:

instead of '||' i replaced with '&&' and got the answer....

回答2:

!Character.isLetterOrDigit(source.charAt(i)) || Character.isSpaceChar(source.charAt(i))

Is the code you want assuming you DONT want white space characters and only numbers or characters.

Use this condition

for (int i = start; i < end; i++) { 
    if (!Character.isLetterOrDigit(source.charAt(i))) {
        if (!Character.isSpaceChar(source.charAt(i)))
            return "";
    }
}
