operations can evolve relatively freely. The visitor pattern makes it easy to add new operations by adding aA new visitor class. The visitor pattern concentrates the behavior on a visitor object, rather than spreading it to aIn each of the node classes. When using the visitor pattern, put as much of the object navigation logic in the visitor class as possible, instead of putting it in its subclass. The visitor pattern can span several classes of hierarchy access to different levelsThe member cl

By default, ' Sublayer ' is displayed outside the ' mask ' content, when ' mask ' is actually transparent, and thus ' greenhead ' is also transparent. Now we want ' greenhead ' to show the content slowly from the top left and bottom right, so we just need to fill in the contents of ' Greenhead ' from two directions.[Full Code] (Https://github.c

good design method, and memory consumption should not be overlooked. In the real world, in an internationalized application, all constants are defined in various languages. A very humble code error can affect a class that has already been loaded. Finally, the result is. In the permanent generation of the application, the JVM will have a outofmemoryerror error. Crash at the same time.Application server also faces an issue with class loader leaks. The main reason for these leaks is that the class
