本文介绍了一个简单的Java面向对象编程示例，通过自定义Book类来展示如何创建对象并使用它们。示例中定义了Book类，并创建了两个Book对象，分别展示了如何为这些对象赋值及打印相关信息。

1.面向对象，自定义类型。

class Book{
String bookID;
String bookName;
String bookWriter;
String books;
}
public class Tast{
public static void main(String[] args) {
Book[] boks = new bok[4];

Book bok01 = new Book();

int bookID = 2;
Bok bookName = "剑行天下";
Bok bookWriter = "幻";
Bok books = "玄幻";

System.out.println("编号: " + bok.bokID);
System.out.println("书名: " + bok.bokName);
System.out.println("作者: " + bok.bokWriter);
System.out.println("类型: " + bok.boks);

Book bok02 = new Book();

int bookID = 2;
Bok bookName = "剑行天下";
Bok bookWriter = "幻";
Bok books = "玄幻";

System.out.println("编号: " + bok.bokID);
System.out.println("书名: " + bok.bokName);
System.out.println("作者: " + bok.bokWriter);
System.out.println("类型: " + bok.boks);
}
}
