<br />import java.io.*;<br /><br />public class A<br />{<br />public static void main(String args[]) throws IOException<br />{<br />BufferedReader stdin=new BufferedReader (new InputStreamReader(System.in));<br />//char n,p;<br />String name,pwd;<br />int n1;<br />int p2;<br /><br />System.out.println("\tWelcome to  ");<br />System.out.println("*******SHINE IT Training Centre*******");<br />System.out.println("**Please login before u calculate**");<br /><br />do<br />{<br />System.out.println("Enter user name: ");<br />name=stdin.readLine();<br />n1=Integer.parseInt(name);<br />System.out.println("Enter password: ");<br />pwd=stdin.readLine();<br />p2=Integer.parseInt(pwd);<br /><br />//System.out.println("Incorrect input!!");<br />} while ((name!="2208")&&(pwd!="1234"));<br /><br /><br />System.out.println("Successful Login!!");<br /><br />}<br />}<br />

eigther change

while ((name!="2208")&&(pwd!="1234"));

to

while ((!name.equals("2208"))&&(!pwd.equals("1234")));

or

while ((n1!=2208)&&(p2!=1234));
