Java key part-CodePudding

Is there a big share, the more important chapters in the Java and content, facilitate the emphasis of the study in the future

Interface, inheritance, polymorphism, those's not the point, is the foundation,

CodePudding user response:

Many language about the same, the focus is on the ecological environment of the language, especially those that open source software, this is also a Java powerful place

CodePudding user response:

See more basic knowledge, know more about principle, under the agreement

CodePudding user response:

I think the key is not in JAVA, but in yourself!

CodePudding user response:

I think the JAVA object is the focal point, polymorphism, IO, multithreading, collection, network socket programming, the Servlet, the spring framework

CodePudding user response:

I think this is you don't know the key
Primary basis is the focus of your
Intermediate commonly used API is a commonly used type of accumulation is the key framework is a key key code specification is key
Advanced code to understand reading is the key source is key algorithm learning is key
Senior (personal didn't achieve) architecture management interview meeting... The frontal

Words don't think of a project to do eat fatty basic framework design first and then clear code, can be easy to read a general project to run is better than a perfect project running up a easy maintenance of the general project is better than a difficult to maintain perfect project

Company new training process, we still focus on basic grammar of founding, the method of definition, method overloading and rewrite the norms, understanding and application of polymorphism, the implementation of different interface (function interface corresponding Lambda expressions used), the use of annotations, custom, understanding of generics, definition, and using the static static understanding and use; These are the basis of things; Date behind is the use of the collection, the use of API (not only refers to the Date, Calender, it is necessary to use the new API), a String String the commonly used method and flexible using, another is "comparison". The comparison of reference type object, such as sorting, ways and I/O, NIO is needed; For multi-threaded, communications, such as the use of scenario is not much, will need time to mend, thread is more complex, communication on this, the communication in a multithreaded environment, also more complex, we can put a put, met the woman of related technical projects, and again, time also, hehe!

CodePudding user response:

Facing object programming ideas, interface of abstract class and so on, if you want to do Java back-end development, multi-threaded to see more, especially the multithreaded underlying code implementation, many big company all ask this right now

CodePudding user response:

Java thread inheritance and polymorphism, collection, IO is quite important
