这是《Java编程思想》(第三版)上的一个例子，编译时没有错误，运行时它总是报这样一个错误：
java.lang.NoClassDefFoundError: bruceeckel/simpletest/Test
at c03.Assignment. <clinit> (Assignment.java:14)
Exception in thread "main "
不知道是什么原因，“static Test monitor = new Test();”这个语句总是有问题。
package c03;
//: c03:Assignment.java
// Assignment with objects is a bit tricky.

------解决方案--------------------
你的classpath的问题，没有Test这个类
------解决方案--------------------
import com.bruceeckel.simpletest 有问题吧 你系统里面确定有这几个文件夹？
