Experiment two Java object-oriented programming (http://www.cnblogs.com/rocedu/p/4472842.html)

Reference http://www.cnblogs.com/rocedu/p/6736847.html

Extend the design pattern example, experience the application of OCP principle and dip principle, understand the design pattern preliminarily
Use your own study number%6 to take the remainder operation, according to the result of code expansion:
0: Let the system support the Byte class, and add the test code in the MyDoc class to indicate the correct addition, submit the test code and run knot, plus the number watermark
1: Let the system support the short class, and add the test code in the MyDoc class to indicate the correct addition, submit the test code and run knot, plus the number watermark
2: Let the system support the Boolean class, and add the test code in the MyDoc class to indicate the correct addition, submit the test code and run knot, plus the number watermark
3: Let the system support the long class, and add the test code in the MyDoc class to indicate the correct addition, submit the test code and run knot, plus the number watermark
4: Let the system support the float class, and add the test code in the MyDoc class to indicate the correct addition, submit the test code and run knot, plus the number watermark
5: Let the system support the double class, and add the test code in the MyDoc class to indicate the correct addition, submit the test code and run knot, plus the number watermark

Use WHITESTARUML to model the code in experiment two, send class diagram, plus number watermark.
Reference http://www.cnblogs.com/rocedu/p/6736847.html

There are only two classes in a class diagram.

Experiment Summary:
Today, when writing the code, there was an error java.lang.noclassdeffounderror:org/hamcrest/selfdescribing.
Took a lot of detours, and later learned that more than 4.11 version no longer contains hamcrest.
So now there are two ways to solve it:
The 1.junit version drops to 4.11.
2. Import Hamcrest-core-1.3.jar
Later I remember, once I had a junit4.7 version, so I solved the problem.
For the results of this experiment, I am still more satisfied, but because of negligence, late handed a week, in this to the teacher said the sound of hard!
