In the architect , There is a consensus , All programming languages , In fact, ideas are interlinked . As a beginner , You may not get the meaning of this sentence right away , But a journey of a thousand miles , Start with one step , When you really try , It's been a long way , Look back , Will feel different . Back to your question , In fact, all three are OK , Because I learned one of them , Then learn other languages by yourself , The whole span is not that big . From the feedback of the market ,Java
It will be popular , There are considerable gaps in major recruitment websites , first-class Java engineer , It's hot everywhere . When you succeed in achieving your goal , Better improve yourself , At the same time, it has realized its own social value , What you see and think will be completely different , People around you can share the same joy with you . So ,Java/Python/c++
Are better choices for beginners .
In terms of learning difficulty ,C Language and Java Programming languages are relatively difficult programming languages , A comprehensive comparison is made between the two in terms of learning difficulty and learning content ,C Language is more suitable for beginners , because Java Language is a pure object-oriented language , Therefore, the abstraction of language itself is relatively high , This will be more difficult for beginners to understand . in addition , because Java Characteristics of language design structure , study Java Programming usually requires learning to use a series of frameworks , There will be more learning content .
From the perspective of application scenarios ,Java Language is one of the few full scene development languages , stay Web development , Platform development ,Android Development and big data development are widely used .C At present, the main application fields of the language focus on the development of operating system , Container development and embedded development , because C The execution efficiency of the language is relatively high , therefore C Language is widely used in the field of Internet of things . From the perspective of the universality of application scenarios ,Java Language has certain advantages , This will also promote employment .
Now I don't know how to learn with zero foundation and zero experience ? I offer one java Knowledge learning Roadmap , You can learn according to the figure java Relevant technical points .
Since many beginners do not have a systematic learning process , The learning progress is slow , I put together a set 《JAVA Core Knowledge Manual 》, This manual is currently V1.0 edition , The contents are as follows 17 Plates , If you want to learn, you can pull to the end of the text , Click business card , You can get it for free by scanning the code .
Java Basics ,Java aggregate , abnormal & reflex ,IO&NIO, Multithreading ,JVM,Linux,MySql,Spring,Spring
Cloud,Mybatis,Nginx,Redis,Dubbo,Kafka,,SpringBoot, resume .
one ,java Knowledge part
JVM It's primary Java The only way for programmers to grow , study JVM before , You just need to know how the code is compiled Class, Virtual machine loading Class Just run it , study JVM
after , You can deeply understand the process of code from compilation to loading , Creation and garbage collection of objects in memory , Quickly locate performance problems in daily development, etc , Of course, it is also an indispensable bonus in the interview .
2.Java aggregate ：
3. Multithreading concurrency ：
two , Database part
three , Distributed high concurrency architecture
This part is about distributed architecture knowledge , include Redis,Zookeeper, Database performance optimization , Load balancing, etc !
five , Microservice knowledge
There are many small partners interviewed recently , I hope it can help more people successfully pass the interview of large factories , If you need to click on the business card below, you can get it for free , If you think it's useful, please comment on it and forward it to me for three times ~~
