Sometimes we can not use the database and the file system to store data, it is necessary to complete the file-based data calculation. However, Java itself lacks the corresponding class library, which requires hard coding to achieve structured file calculations with complex code and poor readability. There are many issues on the web that look for Java class libraries for file calculations, such as:Http://www.coderanch.com/t/561180/java/java/read-text-f

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
