Answer 1

You are assigning a space to reversed string by
String nstr=" "; so nstr have an extra space along with reversed input string..
Just use

String nstr="";

and then check again..
Hope it helps..

Answer 2

Thanks

Answer 3

String nstr=" ";// space is also a character
SO final string never equals original string

So just initialize with empty string like below
String nstr = "";
