If you prefer the Java programming language, there are a number of options that you can pursue in 2023 to continue building your skills and experience in the field.
Firstly, you can continue working on improving your skills in Java itself. With the release of Java SE 17 and the ongoing development of other Java-based technologies like JavaFX, there will likely be new features and capabilities to learn in the coming year.
Another option is to explore the Java ecosystem, which includes a wide range of frameworks, libraries, and tools that are commonly used in conjunction with Java. Some popular choices include Spring, Hibernate, and Apache Maven for building web applications; and Apache Kafka, Apache Storm, and Apache Spark for working with big data.
You can also pursue learning other JVM based languages like Groovy, Scala and Kotlin as they are compatible and work well with java eco-system.
Additionally, you could consider learning a new paradigm of Java programming which is Functional Programming in Java.
Ultimately, the best choice will depend on your individual interests and career goals, but by continuing to learn and grow as a Java developer, you will be well-positioned to take advantage of the many opportunities that the language and ecosystem continue to offer.
