Test Case: We create a Text thread for testing: class Text implements Runnable{ String name; public Text(String name){ this.name = name; } @Override public void run() { System.out.println(Thread.currentThread().getName() + "--" + name); } } Now let's test the effect of the threa

Recently, as the project draws to a close, I feel it is necessary to share my "Patchwork" Web application development model based on ASP.net MVC 3. By the way, let's make a summary of this project. Keywords:Razor, easyui, entityframework, T4, LINQ to entity, JSON 1)Razor: ASP. NET mvc3 introduces a new view engine. 2)Easyui: A jquery-based UI framework 3)Entityframework:Microsoft's database relationship ing framework 4)

We infer that this parameter will result in the returned result being 0, when the second check starts to process the function g (), an error of division by 0 is generated. It should be noted that this information did not appear before the phrase "during specific walk" because the error was detected during the normal processing of function g, at this time, the value specified for the function g () is not used. The specified function call can
