}

public String getPassword()
{
while(true)
{
System.out.print("\nEnter your password: ");
password=sc.next();
System.out.print("\nEnter Confirm password: ");
cPassword=sc.next();
if(password.equals(cPassword))
{
System.out.println("\nPassword set successfully!!");
return password;
}
else
{
System.out.println("\nPlease enter same passwords!!");
}
}
}
public static void main(String args[])
{
LoginDemo login=new LoginDemo();

String userid=login.getUserID();
String password=login.getPassword();

System.out.println("\n\nLogin credentials:");
System.out.println("------------------------------------------------\n");
System.out.println("\nUser ID: "+userid);
System.out.println("\nPassword: "+password);
