28. Where Does Your Code Live? Java Stack vs. Heap Memory Deep Dive

Ever wonder what actually happens inside your computer when you hit "run" on your Java code? In this video, we pull back the curtain on the Java Virtual Machine (JVM) to solve the puzzle of where your variables and objects actually live. We break down the JVM's two primary memory areas: the Stack and the Heap. You will learn how the Stack acts as your program's short-term memory for local variables using the "Last In, First Out" (LIFO) rule, similar to a stack of plates. We also explore the Heap, which serves as a sprawling warehouse for storing permanent Java objects. In this video, you will learn: • The JVM Ecosystem: How the Java Virtual Machine organizes memory. • Stack Memory: Understanding method frames, local variables, and LIFO execution. • Heap Memory: How the new keyword allocates space for objects and instance variables. • Object References: Why "obj is not the object" and how the Stack uses references (like a remote control) to manage objects in the Heap. • Practical Experiment: Proving that objects in the Heap are distinct and how changing one reference does not affect another. Whether you are a beginner or looking to refresh your knowledge of Java internals, this guide simplifies the complex relationship between references and objects. -------------------------------------------------------------------------------- #Java #JVM #StackVsHeap #JavaProgramming #ComputerScience #CodingTutorial
