Several design patterns that are more common in Java learning Still school-horse soldier teacher roughly speaking, summed up 1. Single case mode (single state mode): There are only a few classes or only one class in the course of the program's operation, "single case Mode". Regardless of how many times the external class calls "construct," the object in memory i

The design pattern is called the procedure Ape's internal strength, before fragmented saw a large part, but oneself has summed up. So this is summed up here. It is worth mentioning that design patterns are not unique to Java. Because of always doing Android. Here we use Java

principle (dependence inversion Principle)This is the basis of the open and close principle, the specific content: TRUE interface programming, relying on abstraction and not dependent on the specific.4. Interface Isolation principle (Interface segregation Principle)Using multiple isolated interfaces is better than using a single interface. or a reduction of the coupling between the class meaning, from here we see, in fact, the design pattern is a sof

Design Patterns in Java I/O 1. Adapter Mode Adapter mode is to transform the interface of a class into another interface acceptable to the client, so that two classes that do not match two interfaces can work together. Often used when a project needs to refer to some open source frameworks to work together, there are interfaces for environmental information ins

These two days, I learned one of the simplest patterns in Java design Patterns--singleton mode.It is said that in the Java design pattern, the total can be divided into 23 kinds: Singleton mode, abstract Factory mode, builder mode

the book to implement the two patterns is completely different (I think this implementation is somewhat arbitrary). the state mode, in particular, uses a separate implementation hierarchy, but I don't think it's necessary unless you assume that the implementation code is not controlled by you (which is, of course, a possibility, but if the code is controlled by you, It is also more concise and practical wi

I saw this article in the Java Forum. The author compared the 32 Java models in a simple language, which has a good inspiration, but unfortunately I didn't give a specific meaning, I added it to the back. These are the simplest introductions. If you want to learn them, I suggest you take a look at Dr. Yan Hong's book "Java
