之后，我们创建一个junit测试代码MoneyTest.java，来测试Money.java和MoneyBag.java类，这里我也把它放在src目录下；如果企业应用，你就要把目录分析的详细些，例如src子目录下放所有的java源代码，test子目录下放所有的junit测试代码：51Testing软件测试网s] `eg6S

b!O(VI+_D4f }0之后，我们在sincky目录下，创建一个build.xml文件，完成它的编译和测试任务，这里我为build.xml文件加了注释，供大家参考：

的项目名称叫money_demo，默认执行的任务是compile，根目录指当前目录，也就是sincky文件夹-->

之后，我们开始运行build文件，开始编译任务：打开cmd命令行，进入sincky文件夹下，执行ant命令，会看见类似下列内容的效果：51Testing软件测试网,b UN\ _|
