Understanding JVM Memory Structure for Java Developers

The Java Virtual Machine (JVM) is the cornerstone of Java’s “write once, run anywhere” philosophy. It provides a runtime environment that executes Java byte code, handling memory management, so developers can focus on building applications rather than dealing with memory allocation and de-allocation. This article explores the JVM memory structure, illustrates how objects move through
