Computer majors usually start learning from C language. The main reason why non-computer majors want to switch to programming is the first choice of Java: the market demand is large.
Java can be used to develop a variety of applications, including enterprise-level web applications, mobile applications, desktop applications, games, embedded systems, cloud infrastructure, and more.
In the field of games, there are also two classic games that we are familiar with, [My World] & [League of Legends]
1. The prospect of Java
In the past three years, many people have bad-mouthed Internet-related jobs, but looking around, whether it is good or not, computer-related jobs will pick up first.
Everyone understands the employment crisis and the workplace crisis, and we all know how important it is to have a "settled down" technology.
From the perspective of the industry, entering 2023, the market of leading companies such as Baidu, Alibaba, and Tencent has gradually stepped out of the bottom of the "V" shape and started to take upward steps. The entire industry is releasing positive signals of recovery. The "2023 New Year Start Employment Report" released by Liepin also shows that talents in the Internet industry are showing a state of "booming supply and demand". If you want to ask the most popular industries for job hunting, job hopping, and career change this year, the Internet must be one of them.
2. How to get started with Java
Let's first look at the full version of the Java2023 difficult learning roadmap published by Dark Horse Programmer:
Stage 1 Java foundation: Possess Java language programming foundation and IO, multi-threading, network programming and other development capabilities, but do not meet the enterprise employment standards, which can lay a solid foundation for later learning
Phase 2 JavaWeb: Master the basic concepts of servers, master the basic knowledge of JavaWeb development, master the basic use of databases and Java operation databases, and meet the primary needs of the Java software development industry
Stage 3 Java development framework: Master the basic process of SpringBoot development, MybatisPlus database-side operation, front-end framework vue, can handle junior and intermediate positions in Java development, and the salary can reach 9,000-12,000 yuan/month according to the relevant job search website data
Stage 4 Middleware & Service Framework: The course at this stage is in line with the development trend of the Java development market. Students can easily handle most positions in Java Internet development. According to market feedback, the salary can reach 15,000-18,000 yuan/month
Phase 5 project actual combat: simulate the real project scenario of the enterprise, improve the technical application ability and project solution ability
Interview topics of six major factories in the stage: Focusing on the high-frequency interview questions of major factories, give detailed answers, and carefully design for topics such as JVM, database optimization, Spring series, and distributed series!
三、Java学习方法
转行最重要的事情就是找工作。那么就要围绕着现在企业需求去学习技能，当下第一份工作所需要的基本技能就是Springboot。至于分布式、高并发、微服务，我建议找工作后有了一定实际工作经验再学。或者你实在找不到工作，作为加分项学习。
下面是一些少走弯路的经验：
Java高薪是真的吗？是！
只要成功找到Java工作，月薪过万是吧难的，哪怕刚开始第一份工作没过万，未来过万的问题也不大。但是通过自学Java，找到工作，并不简单。
学Java技术栈和Java工作的经验侧重不同，找Java工作的重点在于，第一有项目经验，第二自己熟练掌握在项目中的必要技术。
