Garbage Collection and Memory Profiling

In the intricate dance of Java Virtual Machine (JVM) internals, where bytecode is compiled and programs are executed within the confines of register memory, an indispensable aspect emerges the artful orchestration of memory resources. After traversing the realms of bytecode compilation and program execution, it is paramount to delve into the nuanced domain of memory management within the JVM. This chapter embarks on a comprehensive exploration of garbage collectors (GCs), unraveling the intricate tapestry governing Java programs’ sustenance.

Our journey through the inner workings of the JVM reaches a crucial juncture as we unravel the mysteries of memory allocation, heap structures, and the ever-pivotal garbage collection mechanisms. By comprehending the nuances of memory management, including distinctions between heap and stack, and mastering the intricacies of garbage collection, you will enhance your understanding of JVM internals...
