Java方法的调用

1、package com.liushuo;/*** 图书类* @author shuoLiu*Date:2016-3-1*/public class Book { public String bookName; public String authorName; public int pageNum; public boolean isAvailable; public void bookAvailable(){ if(isAvailable==true){ System.out.println("借阅成功"); isAvailable=false; } else{ System.out.println("该图书已经被借出！"); }}public void showBookDetails(){ System.out.println("图书名为"+bookName+"，作者名为"+authorName+"，书页为"+pageNum+", "+isAvailable+"");}}

2、package com.liushuo;public class Test02 {public static void main(String[] args) { Book book=new Book(); book.bookName="明朝那些事儿"; book.authorName="当年明月"; book.pageNum=159; book.isAvailable=true; book.bookAvailable(); book.showBookDetails(); Book book1=new Book(); book1.bookName="平凡的世界"; book1.authorName="路遥"; book1.pageNum=264; book1.isAvailable=false; book1.bookAvailable(); book1.showBookDetails(); }}
