Class not found exception in java?

I have two classes in the same package(users).

the first class:

package users;

public class Account{
  public String username;
  public String password;
}

the second class:

package users;

public class employee{

  public void login() {
    Account a = new Account();
    a.username = "MHM";
    a.password = "15234785";
    System.out.println("Username: " + a.username);
    System.out.println("Password: " + a.password);
  }
}

In the main page when i called the method(login):

it says to me: java.lang.ClassNotFoundException: Account

  package users;

  public class Main{

    public static void main(String argv[]) {
      employee e = new employee();
      e.login();  
    }
  }

what is the fix for this error?

note: these classes were written in the default package then i create package users then move them into the new package.... before moving them in the new package they were working good but after moving the problem is occurs.

As per see this,

First of all keep in mind that, In one/single package maximum 1-class should be public, more than 1-class as a public modifier not possible.

As i seen you code, it seems that you forget Data-type,

make it correct like,

package users;


class Account{
  public String username;
  public String password;
}

class employee{

  public void login() {
    Account a = new Account();
    a.username = "MHM";
    a.password = "15234785";
    System.out.println("Username: " + a.username);
    System.out.println("Password: " + a.password);
  }
}

public class MyMainClass{
   public static void main(String [] args){
    // block of code... 
  }
}

If you want more classes a public modifier then do it by make individual package for all public class.

EDITED

  package users;

    class Account{
          public String username;
          public String password;
        }

    class employee{

          public void login() {
            Account a = new Account();
            a.username = "MHM";
            a.password = "15234785";
            System.out.println("Username: " + a.username);
            System.out.println("Password: " + a.password);
          }
        }


    public class MyMain {

        public static void main(String[] args) {
            employee e = new employee();
            e.login();  
        }

    }

 /*
Output : 
---------------
Username: MHM
Password: 15234785

java.lang.ClassNotFoundException: Account

Your Account class is not compilable.Change your Account class like this

public class Account{
public String username;
public String password;
}

UPDATE

Tested your code.There is no other issue except this.Its working fine.

Its throwing ClassNotFoundException because your Account class has not been compiled . Hence .class file has not been generated.

To make the compilation successful Account class as below :

public class Account{
public String username;
public String password;
}

Just do this all it's ok:

 public class Account{
   public String username;
   public String  password;
}

The variables should be have a type

Account class will not compile because username and password need the object type. i.e, String.

public class Account{
  public String username;
  public String password;
}

Your Account class is not defined properly. You forgot to add the types of the variables "username" and "password". It should probably be:

public class Account{
public String username;
public String password;
}

(Not to mention that public global variables are never a good thing to choose (instead use getters and setters) - but that's a different topic here :) )
