userbean.java

Java 2实用编程百例,一些比较实用的J2SE小程序,可以通过这些程序熟悉JAVA基础知识

package ch04.section10;

import java.util.*;

public class UserBean {
  private HashMap user;
  public UserBean() {
    user = new HashMap();
    user.put("admin", "admin");
    user.put("guest", "guest");

  }

  public boolean validUser(String username, String password) {
    if ( (user.get(username) != null) &&
        ( ( (String) user.get(username)).equals(password))) {
      return true;
    }
    return false;
  }
}
