随着互联网技术的快速发展，Java开发人员更是成为了互联网企业必备的人才，越来越多的人将学习Java看成是转行的捷径，这也让Java开发成为如今热门的岗位。那么，学完Java后可以应聘哪些岗位，学完后可以从事哪些工作?
1. In the field of web development, the Java language is currently widely used in the field of web development, big data (including cloud computing, edge computing), and mobile Internet. Among them, there are web development positions in the web development field (requires certain front-end knowledge) , Back-end development positions, architect positions, etc., JavaWeb full-stack development positions are currently more popular with enterprises. Java Web full-stack development requires front-end development knowledge and back-end development knowledge, involving JavaScript, database, distributed development, etc.
2. In the field of big data, specific positions include big data platform development, big data application development, big data analysis, and big data operation and maintenance. Among them, the demand for big data application development and big data analysis is relatively large. Java language is a relatively common choice for platform research and development. For example, the Hadoop platform is developed using Java language. For Java programmers, there will be more room for development in the future of platform-based R&D programmers and career life cycle. It's also relatively long.
3. In the field of mobile Internet, Java is mainly used for Android application development and back-end service development. Although Kotlin can also be used for Android development, most Android programmers prefer to use the Java language. Java language has further consolidated its position in the mobile Internet era with the help of Android development. It can be said that a full-scene mobile Internet development environment (from front-end to back-end to the cloud) can be constructed through Java language.
There are many positions in Java development, and different positions also have differences between junior programmers, main programmers and R&D experts, so there is also a big gap in salary. In general, if you can successfully learn Java later, then The salary package in the future is still considerable.
