添加手册和打印手册详细信息- Java

Question

我对Java很陌生&我一直在处理set任务，到目前为止，我正在执行一项要求我执行的任务：

"3.设计并实现一个名为library的类，它可以包含库中所有手册的详细信息。您的类应该(至少)有方法添加手册并打印所有手册的详细信息。“

我已经有了一个“手动”类，如下所示(基于前两个任务集)：

public class Manual {

    String serialNumber, title, author;

    public static void main(String [] args){
        Manual man= new Manual();
        man.print();
    }

    public Manual(){
        set("??????", "Untitled", "Unknown");
    }

    public Manual(String serialNumber, String title, String author)
    {
        set(serialNumber, title, author);
    }

    public String getserialNumber()
    {
        return serialNumber;
    }

    public String getTitle()
    {
        return title;
    }

    public String getAuthor()
    {
        return author;
    }

    public void set(String serialNumber, String title, String author)
    {
        this. serialNumber = serialNumber;
        this. title = title;
        this.author = author;
    }

    public void print()
    {
        System.out.println("Serial Number : " +serialNumber);
        System.out.println("Title : " +title);
        System.out.println("Author : " +author);
    }

    public void print(String heading)
    {
        System.out.println(heading);
        print();
    }

    public void ask()
    {
        serialNumber = Console.askString("Please enter the serial number: ");
        title = Console.askString("Please enter the title: ");
        author = Console.askString("Please enter the author: ");
        set(serialNumber, title, author);
    }

    public String toString()
    {
        return "SerialNumber: " + serialNumber +"\n"
               +"Title: " + title + "\n" 
               +"Author: " + author +"\n";
    }

    public void print()
    {
        System.out.println(this.toString());

    }
}

接下来，是我试图正确完成的库类：

public class Library {

    public void print(String header){
        Manual.print(header);   }

    public void ask(String prompt) {
        Manual.ask(prompt);

}
}

我是否已经根据我的库类中存在的内容完成了这个问题？如果有人能教我是否有任何错误存在，或者如果我遗漏了代码的部分，以便完成任务，我将非常感激。

谢谢

按照我的逻辑，我认为这样做会更好

/图书馆班

import java.util.*;



public class Library 
{


public static void main(String[] args) 
{

String serialNumber, title, author;


Scanner input = new Scanner(System.in);


System.out.print("Please enter the serial number: ");
serialNumber = input.next();

System.out.print("Please enter the title: ");
title= input.next();

System.out.print("Please enter the author: ");
author = input.next();

Manual man= new Manual(serialNumber,title,author);

man.print();


}


}

/手册班

public class Manual 
{
String serialNumber, title, author;


public Manual(String serialNumber, String title, String author)
{
setSerialNumber(serialNumber);
setTitle(title);
setAuthor(author);
}

//// serial number

public void setSerialNumber(String number)
{
serialNumber = number;
}


public String getserialNumber()
{
return serialNumber;
}

public void setTitle(String mytitle)
{
    title = mytitle;
}
public String getTitle()
{
    return title;
}

public void setAuthor(String myAuthor)
{
author = myAuthor;
}
public String getAuthor()
{
return author;
}

public void print()
{
System.out.println("Serial Number : " +serialNumber);
System.out.println("Title : " +title);
System.out.println("Author : " +author);
}

public void print(String heading)
{
System.out.println(heading);
printing();
}


public String toString()
{
return "SerialNumber: " + serialNumber +"\n"
+"Title: " + title + "\n" 
+"Author: " + author +"\n";
}

public void printing()
{
System.out.println(this.toString());

}
}

作为建议，总是做简单的事情，简单但合乎逻辑的代码。我也和你一样是初学者。这就是我一直被告知的

希望能帮上忙
