I. Introduction
Java 8 has brought many new features, one of which is usually used more often, one is set processing based on stream mode, which combines another key knowledge point-functional programming, which can be used in Lambda expressions A functional interface is passed into the stream to change the stream. The other is the new time processing API, which is not used a lot at present. From the API level, it is more reasonable and unified. If there is a chance in the future work process, I will use this more!
2. Introduction of new features
I didn’t go to look at the others too much in this area. I was familiar with it over and over again through a courseware. It was basically enough. If there are any omissions, just add it!
Just post the resource link below and record it!
