Project Valhalla 설명: 10년 작업이 JDK 28에 도착하는 방식

Project Valhalla's Value Classes reaching JDK 28 preview represents a decade-long effort to solve Java's fundamental inefficiency in object memory layout and CPU cache utilization. By enabling value types that 'code like a class but work like an int,' Java developers can now achieve dense memory storage and eliminate costly pointer indirection without sacrificing object-oriented safety. This paradigm shift will fundamentally reshape how Java optimizes performance-critical applications across the industry.
