  package com.maple;

  public class Book {
   Book(){                                    //无参构造函数
    
   }
   Book(int newNumber,String newName){        //构造函数的值实现数组的传递；   //有参构造函数
    this.number=newNumber;
    this.name=newName;
   }
   private int number;   //私有变量
   private String name;
   public int getNumber(){     //实现私有变得传值过程   get , set
    return number;
   }
   public void setNumber(int newNumber){
    this.number=newNumber;
   }
   public String getName(){
    return name;
   }
   public void setName(String newName){
    this.name=newName;
