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
