Did you know that Java behaves differently when comparing wrapper classes like Integer? 🤯 In this quiz, we test a simple line of code: Integer a = 128; Integer b = 128; System.out.println(a == b); Most beginners expect true, but the correct output is: ❌ 👇 Watch the video to learn why Java outputs false here! This happens because of Integer caching mechanism in Java — only values between -128 to 127 are cached. Anything outside that range creates a new object, so == compares references, not values. 🧠💡 --- 🎯 You'll Learn: ✔ Java wrapper class behavior ✔ Integer caching ✔ Difference between == and .equals() ✔ Common Java interview question --- 💬 Comment below: Did you get it right? 😎 --- 🔍 Keywords: Java quiz, Integer caching, Java interview question, wrapper classes, Java comparison, Java coding challenge, Java beginner tips, Java programming trick --- 📌 Hashtags: #Java #JavaQuiz #CodingQuiz #ProgrammerLife #JavaInterview #JavaTips #CodingChallenge #LearnJava #DeveloperCommunity #ProgrammingFacts #JavaDeveloper #CodeSmart #SoftwareEngineer #TechLearning #programminghumor
