Topics to avoid for your next Java Developer Interview
1. JavaFX
According to Oracle docs, JavaFX is a set of graphics and media packages that enables developers to design, create, test, debug, and deploy rich client applications that operate consistently across diverse platforms.
In simple words, JavaFX is a graphical user interface(GUI) toolkit.
Developers can create mobile and desktop applications by using JavaFX.
It supports modern programming techniques like reactive programming and event-driven programming.
Reason To Avoid
According to our survey, 98% of Java-based projects do not use JavaFX in their tech stack. Until it is mentioned in the job description, you should not prepare this topic for your next Java interview.
2. Outdated Java Versions
Outdated Java versions refer to versions of the Java programming language that is no longer supported by Oracle Corporation. These versions do not have the latest features or security updates.
Java 6 was released in 2006 and its support ended in 2013.
Java 7 was released in 2011 and its support ended in 2015.
Java 8 was released in 2014 and is currently the most popular and widely used Java version in the industry.
You should not spend too much time on outdated Java versions. For now, outdated Java versions include Java 6 or earlier version. Instead, you should focus on the latest versions i.e. Java 8 or above.
Reason To Avoid
Outdated Java versions are difficult to maintain because it is hard to find resources or support for your code, especially if you encounter problems or errors.
3. Java Swing
Just like Java FX, Java Swing is also a GUI (Graphical User Interface) toolkit that allows developers to create rich user interfaces for Java-based desktop applications.
Swing was introduced in JDK1.2. It replaced the AWT(Abstract Window Toolkit) that was introduced in JDK 1.1.
It provides a rich set of components such as text fields, buttons, labels, trees, and more.
It is platform-independent and can create GUIs for various operating systems such as Linux, MacOS, and Windows.
Reason To Avoid
It is similar to JavaFX but JavaFX was designed from the ground up to support modern UI design standards, while Swing was designed to be a more traditional toolkit. If the job description specifically asked for Java Swing then only go through it once. Otherwise, just skip it and focus your energy on preparing other important Java topics that have a higher probability of getting asked in your next Java developer interview.
4. Java AWT
AWT stands for Abstract Window Toolkit.
It is the oldest Graphical User Interface toolkit for Java.
AWT is a platform-dependent toolkit. In simple words, the appearance of the components depends on the underlying operating system.
Reason To Avoid
One of the main shortcomings of AWT is its lack of support for advanced graphics and multimedia features and is platform dependent. According to our survey, 99.8% of Java Projects do not use AWT. If you see AWT written in the job description, then I will recommend thinking twice before applying for that job.
