Where to go Web Internship Summary: Recursive construction of the "Process run Order" XML file (Javaweb)

Originally to do the purpose of data mining in which network, the structure has become a system development ...

Just still more serious to do for three months, the teacher very much agree with my work attitude and results.

。

The internship is coming to an end, summarizing a few things that have not been noticed before and become habits and problems. Share to everyone.

At the same time to make an advertisement: to which network Internal audit department recruit Javaweb Development intern, Time is very free. Every week One days, Saturday Sunday even can, the time is ample of small partners to leave a message to me Ah, earn a pocket money, still can have a long experience.

。。。 (GPA, want to work a senior dog is the most suitable only ...

）

The structure of map is (Thisprocessid, thisprocesstype;nextprocessid1,nextprocesstype1; Nextprocessidk,nextprocesstypek;), assuming the processtype part start, end, split, join, the type and ID are the same ....

Run the code and you'll know what's going on. Directly on the code:
