编译错误，因为第一行的括号没有正确关闭。应该为：

public static void main(String[] args) { Book OneBook = new Book("Java Web 程序设计"); Book TwoBook = new Book("MySQL 数据库基础"); TwoBook.Publisher = "电子工业出版社"; System.out.println(OneBook.ShowBook0() + "\nPublisher: " + Book.Publisher); System.out.println(TwoBook.ShowBook0() + "\nPublisher: " + TwoBook.Publisher); }

class Book { static String Publisher; String Title; Book(String title) { Title = title; } public String ShowBook0() { return("Title: " + Title); } }

输出结果为：

Title: Java Web 程序设计 Publisher: null Title: MySQL 数据库基础 Publisher: 电子工业出版
