Summary

In this chapter, we delved into the intricate mechanisms that govern the execution of Java applications within the JVM. From understanding the intricacies of memory management, exploring the Java stack, and unraveling the mysteries of native method stacks, to witnessing the dynamic compilation prowess of the JIT compiler and the crucial role played by the Code Cache, our journey has been one of decoding the inner workings of a Java application in action.

As we bid farewell to the realm of code execution dynamics, our next destination awaits, where we’ll explore a fundamental aspect of runtime management: the garbage collector. Join us in the upcoming chapter as we unravel the intricacies of memory cleanup and resource management, which is essential for maintaining the health and efficiency of Java applications. The garbage collector beckons, promising insights into how the JVM gracefully handles memory de-allocation and ensures the longevity of Java applications....
