This certification level seeks to improve your performance and code clarity, including methods on how to use new Java features and reduce your development times. Alternatively, software engineers have a broader skillset to work on different programming languages and projects. As Java developers and software developers have similar roles and skills, many professionals transition between the two roles for variety, a new challenge, or to learn new skills. Speaking from programming notions, Java is concurrent, class-based, object-oriented, and based on bedrock languages like C and C++. This makes java extremely versatile, coder friendly, and skill-set in demand. With most large-scale companies having their software systems and backend services implemented in java, a java developer is one of the most sought jobs of 2021. You can use your expertise to teach online and in-person classes to aspiring Java developers, helping to increase your credibility in the industry.

The success of Java and its write once, run anywhere concept has led to other similar efforts, notably the .NET Framework, appearing since 2002, which incorporates many of the successful aspects of Java. Like Java, .NET languages compile to byte code and are executed by the Common Language Runtime , which is similar in purpose to the JVM. Like the JVM, the CLR provides memory management through automatic garbage collection, and allows .NET byte code to run on multiple operating systems. First, like other standard code libraries, the Java libraries provide the programmer a well-known set of functions to perform common tasks, such as maintaining lists of items or performing complex string parsing. Second, the class libraries provide an abstract interface to tasks that would normally depend heavily on the hardware and operating system. Tasks such as network access and file access are often heavily intertwined with the distinctive implementations of each platform. The java.net and java.io libraries implement an abstraction layer in native OS code, then provide a standard interface for the Java applications to perform those tasks.

Chapter 7 (“Alternative JVM Languages”) introduces this third part of the book focused on alternative JVM languages. This chapter covers why one would be interested in an alternative JVM language before delving into how alternative JVM languages can be used to support functional programming concepts on the JVM. The chapter outlines different ways to classify non-Java JVM languages such as interpreted versus compiled, statically typed versus dynamically typed, and imperative versus functional. The chapter also contrasts completely new languages designed for the JVM with “reimplementation” languages (pre-existing languages ported to the JVM such as Jython, JRuby, and Rhino).

This certification was one of the first exams I was considering after I was done with my college courses regarding Java and object-oriented programming. This was a time when I started working in programming and sort of needed to improve my rather basic knowledge in this area. Upsides include more recent language knowledge being tested as well as a great way to prepare for both the certification and my thesis. On the other hand, the older SCJP exam for Java 6 was split into two exams increasing the overall price and also covered far more ground because of the additions in Java 7 release.
