(3) model match
The Java code provides a data model that meets the requirements of the display layer. The display layer framework matches the data model and template to generate results.
Including wicket, fastm, domplus, and so on.
As with swing, Wicket provides different view models for different UI component, such as tables, lists, and labels. Fastm and domplus support pojo, but they also need to meet some framework-specific conven

Question: 1 + 2 + 3... + N. It is required that keywords such as multiplication and division, for, while, if, else, switch, case, and condition judgment statements cannot be used.
Problem Analysis:
You cannot use multiplication or division, so you cannot use the n (n + 1)/2
