Design patterns in Java include basic & simple patterns that every programmer must know. By using the design patterns, java developers can make their code more flexible, reusable, and maintainable. To learn about this topic, you can prefer online courses or books like — “Head First Design Patterns”.
5. Big Data
Java Developers who work with Java must know Big Data. Big Data like Hadoop and HDFS process a huge set of data to get insights into a trend. Thus, a developer needs to know big data and complex pattern analysis.
6. SQL
The next thing that a java developer should know is SQL — a language for relational databases. SQL is a programming language that’s in demand within the tech industry. The majority of software developers who know SQL earn lucrative salaries.
