Exploring Top Courses for JVM, Garbage Collection, and Performance
Written on
In the realm of Java development, understanding the Java Virtual Machine (JVM) and effectively managing memory is vital, particularly for senior developers. The JVM does handle memory management, but lapses in coding practices can lead to memory leaks in Java applications. Knowing how to properly configure the JVM and troubleshoot memory-related issues is essential for advancing in this field.
If you're eager to enhance your knowledge of JVM internals, garbage collection, and performance tuning this year, you've arrived at the right resource. Previously, I’ve recommended books and articles that delve into JVM concepts, and now I'll highlight some online courses that can deepen your understanding of these critical topics.
While not many courses focus on the nuances of JVM internals and garbage collection algorithms, Pluralsight offers a comprehensive series that thoroughly examines these subjects, including ClassLoading, Memory Management, and Security. This has been a reliable resource for me whenever I need to brush up on my knowledge.
Additionally, there are several excellent courses on Udemy that cover JVM internals and memory management. For those serious about elevating their Java skills, investing time in understanding JVM internals is essential; it can distinguish a proficient developer from one with only a few years of experience.
Top 7 Courses to Master JVM Internals, Garbage Collection, and Memory Management
As previously mentioned, there are limited high-quality courses available online for learning about JVM internals and memory management. These topics are often viewed as advanced, and many Java developers may overlook them.
However, as performance expectations rise, senior Java developers are increasingly required to possess a deeper understanding of the JVM.
1. Java Application Performance and Memory Management
For senior Java developers seeking to enhance their application performance skills, this is an ideal starting point. The course covers common causes of performance issues, including threads, memory, and garbage collection, along with effective resolution strategies.
Participants will learn best practices for optimal coding choices during the design phase and explore various configurations to improve JVM performance at runtime. The course also delves into memory management and garbage collection processes.
