各位大神帮帮忙!

小弟初学Java,看一个程序,真不懂什么意思。。。。



public class Book_Practice
{
    private String author;
    private String title;
    private int pages;
    private String refNumber;
    
    public Book_Practice(String bookAuthor,String bookTitle,int pages)
    {
        author=bookAuthor;
        title=bookTitle;
        this.pages=pages;
        this.refnumber=0;
    }
    
    public void printAuthor()
    {
        System.out.println(author);
    }
    public void printTitle()
    {
        System.out.println(title);
    }
    public int getPages()
    {
        return pages;
    }
    public void printDetails()
    {   
        if(strlen(refnumber)!=0)
        {
            System.out.println("书名:"+title",作者:"+author",页数:"+pages+"签名"+refnubmer");
        }
    }
    
    public void setRefnumber(String ref)
    {
        refNumber=ref;
    }
    
    public int getRefnumber()
    {
        return refNumber;
    }
    
    public void borrowBook()
    {
        
    }
}



public后面的作用是什么?还有get和return? --------------------编程问答-------------------- 买本Java入门的书看吧,来论坛扫盲对你自己来说效率太低了,不值得。 --------------------编程问答-------------------- 不知道楼主要看它干嘛?先学习走路吧,别想马上就跑起来。
