I am trying to compare data in database with user entered data,
even though both the values are same its showing me they are not equal..
and I also noticed one more thing ,my strings length in database is 2 more that the original length, [ database value= panda then length should be 5 , but its showing me as 7]

String username=request.getParameter("username"); String password=request.getParameter("password"); rs = stmt.executeQuery("select * from LOGIN1 "); while (rs.next()) { String s=rs.getString("NAME"); out.print("database data length :"+s.length()+ "username lenght: "+ username.length()); if(username.equals(s)) { out.println(" true"); } out.print("false"); }
