; At the code level . ,If A is set by Group B , then a will contain the global variables of B, and create B at the same time as the creation of a, in the code we usually use constructs function for Real Now,It is also the implementation of the constructor in the dependency injection.Illustration: Solid Diamond + solid line + arrowExample: Summary Finally, we summarize, generalization and implementation will not be much, we all understand, is to inherit and implement the interface, focus on the o

Common code blocks in Java, building blocks of code, static code block differences, and code examplesThe static code block and the execution of the constructor sequence, has been very confused, read Sun Weichen teacher's "Java Object-oriented programming" and the teacher's Java basic Video in the explanation, now use the following small procedure to brief the nar
