java Implements Access Control System

The specific code for java to implement the access control system is shared for your reference, which is as follows:

Door.java

package com.handson.sys;
 
public class Door {
 public final static String OPEN = " Door open ";
 public final static String CLOSE = " Door closed ";
 private String state = CLOSE; //  Electronic door status 
 private boolean bellState = false; //  Door Bell Status 
 
 //  Construction method 
 public Door() {
 this.setState(CLOSE);
 }
 
 //  Open the electronic door 
 public void open() {
 this.setState(OPEN);
 }
 
 //  Close the door 
 public void close() {
 this.setState(CLOSE);
 }
 
 // setter/getter
 public String getState() {
 return state;
 }
 
 public void setState(String state) {
