自己搞定了嘿。。。運行OK!??? 構造數組才是這題的解法！

package com.maple;

public class Book {
?Book(){??????????????????????????????????? //無參構造函數
??
?}
?Book(int newNumber,String newName){??????? //構造函數的值實現數組的傳遞；?? //有參構造函數
??this.number=newNumber;
??this.name=newName;
?}
?private int number;???//私有變量
?private String name;
?public int getNumber(){???? //實現私有變得傳值過程?? 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;
?}
}
