The modified calculator Code has the following problem: If you need to add a new operation class, in addition to modifying the interface code, you also need to add a new statement in the switch of operaationfactory! Using C # reflection technology can solve the problem well. The following code does not use DLL. For exa

In fact, this program is the first sophomore semester in Java, a normal job, at that time only required to produce a few random matrices and the calculation of these matrices.So I didn't go to the present so rich and practical function. But at that time was quite want to do, but some do not know how to achieve.Now is the junior semester, before soon after the end of the exam, idle to the matter before the fall of this thing to fill up, but also a big worry about the old one.The
