The Set calculator assists java in processing the set operation of structured text, and java structuring
JAVA does not directly support set operations. Therefore, you must use nested loops to perform set operations such as intersection, union, and difference sets between text files. If there are many files, or if the file is large and cannot be directly computed in the memory, or you need to perform Set Operations Based on Multiple Fields, the corresp
The Set calculator assists Java in processing grouping and summarizing structured text, and java structuring
Using Java to group and summarize style files may cause the following troubles:
1. files are not databases and cannot be accessed using SQL. When the grouping and summary expressions change, you can only rewrite the code. To implement flexible expressions, You need to parse and evaluate dynamic expressions by yourself. The programming workload
The Set calculator assists Java in processing conditional filtering of structured text, and java structuring
Using Java to filter data in text files by conditions may cause the following troubles:
1. files are not databases and cannot be accessed using SQL. When the filter conditions change, you must rewrite the code. If you want to implement SQL-like flexible conditional filtering, You need to implement dynamic expression parsing and Evaluation on yo

Software four-layer switching we can use the common LVS on Linux to solve, LVs is Linux Virtual Server, he provides a real-time disaster response based on the Heart Line heartbeat solution, improve the system robustness, At the same time, the flexible virtual VIP configuration and management functions can meet a variety of application requirements, which is necessary for distributed systems.

I have been busy recently. I haven't written it in a few days. Today, I am working on the application of structured structures (Student Achievement Management). I believe many of my friends have done this. I am ugly here and it is difficult to control C. So there are many not very good functions in it, you can complete it on your own.

the most platforms.Personally, I rarely use XML these days. If the consumer is a browser or a public API I tend to use JSON. For internal APIs I tend to use protobuf for performance.The personal view is that:1. The structure relative to Xml,json is more closely related to "object-oriented" programming. JSON is more concise and conveys the same meaning, with fewer bytes in JSON, less content to transmit, and relatively faster.2. Why use Protobuf? What are the advantages of relative JSON? The pr

The process-oriented analysis method is a bit like solving mathematical problems, which must be followed sequentially, if one step is wrong, then all re-start after the overthrow.Object-oriented analysis method is like painting a picture, the problem is divided into the object is the class, the first painting the characters, then painting the scenery, finally the people to contact the landscape, a project is completed.Object-Oriented analysis method is more suitable for the current research and

This mode is used to cope with the branches produced by multi-choice or-split.
First, the merging of this branch requires understanding the context relationship. If only branch a is generated before, only branch a can trigger the rear body, and branch B is also used. If branch a and branch B are concurrent, pay attention to the word "synchronizing" in the title. The merge must wait until branch a and branch B are completed before triggering the rear C.
