How Does the JVM Choose the Right Method? Inside Stack Frames and Dynamic Dispatch

This article explains how Java’s JVM uses stack frames, local variable tables, operand stacks, dynamic linking, and method return addresses to manage method calls, detailing the distinction between static and dynamic dispatch, the role of non‑virtual methods, and how the invokevirtual instruction resolves the correct implementation at runtime.

Understanding Swift SIL and Method Dispatch Mechanisms

Swift inserts the high‑level SIL intermediate representation between source code and LLVM, exposing type declarations, method blocks, and virtual tables, while supporting three dispatch strategies—direct for value types and final methods, VTable for regular class methods, and Objective‑C message dispatch for @objc dynamic methods—crucial for debugging mixed Swift/Objective‑C and protocol‑extension behavior.
