关于thinking in java 中的一些菜鸟问题

Java code

//:c04:SimpleConstructor.java// Demonstration of a simple constructor.import com.bruceeckel.simpletest.*;class Rock{    Rock(){//This is a constructor        System.out.println("Creating Rock");    }}public class SimpleConstructor{    static Test monitor = new Test();    public static void main(String[] args){        for(int i = 0;i < 10;i++)            new Rock();        monitor.expect(new String[] {            "Creating Rock",            "Creating Rock",            "Creating Rock",            "Creating Rock",            "Creating Rock",            "Creating Rock",            "Creating Rock",            "Creating Rock",            "Creating Rock",            "Creating Rock"        });    }} ///:~

直接照书上抄的！

编译时出错啦！

就是那个包的问题：import com.bruceeckel.simpletest.*

还有就是static Test monitor = new Test();这句话是干什么用的呀！？

貌似没有Test类呀！

高人指教！

[解决办法]
莫非Thinking in java出第五版了？
我找到的第4版代码是这样的

Java code

//: initialization/SimpleConstructor.java// Demonstration of a simple constructor.class Rock {  Rock() { // This is the constructor    System.out.print("Rock ");  }}public class SimpleConstructor {  public static void main(String[] args) {    for(int i = 0; i < 10; i++)      new Rock();  }} /* Output:Rock Rock Rock Rock Rock Rock Rock Rock Rock Rock*///:~
