Java OCP 21 1Z0-830 | Handling Values 1.2.1 | Arithmetic Expr — Precedence, Type Promotion & Casting

Java OCP 21 Exam (1Z0-830) — Handling Values Series Video 1.2.1 : Arithmetic Expressions — Operator Precedence, Type Promotion & Casting In this video you will learn: ✅ Operator precedence — * / % always before + - and why it matters ✅ Integer division truncation — 7/2 = 3, NOT 3.5 ✅ Modulo with negatives — sign always follows the left operand ✅ Post vs pre increment — i++ vs ++i in expressions ✅ Type promotion — why byte + byte = int, not byte ✅ The classic compile error: byte d = a + b ✅ Widening — automatic, no cast needed, no data loss ✅ Narrowing — always needs an explicit cast ✅ Compound assignment += has an implicit cast built in ✅ Why x += 1 compiles but x = x + 1 does not for byte ✅ Literal assignment — compiler range check at compile time ⏱ Timestamps 0:00 Introduction & Hook 00:44 Arithmetic Expressions - Operator Precedence Table 07:21 Arithmetic Expressions- Type Promotion & Casting — Compile Errors 🎯 OCP 21 Exam Objective: "Evaluate arithmetic expressions using the Math API, applying precedence rules, type conversions and casting" 📺 Watch the full OCP 21 Handling Values playlist: https://www.youtube.com/playlist?list=PLXgr9iga1fVwr0UPtK4bqLINB9qjwr-zq ⬅ Previous video — Primitives, Wrapper Classes & Integer Cache: https://youtu.be/fsvjaWflVhw ➡ Next video — Boolean Expressions, Short-Circuit & Math API: 📝 Practice Questions: 👉 OCA 8 (1Z0-808): https://javalearn.clustermicro.com — Live now 👉 OCP 21 (1Z0-830): https://javaocp.clustermicro.com — Coming Soon 📧 Early access: [email protected] 🔔 Subscribe for the complete OCP 21 series covering all exam objectives. #JavaOCP21 #Java1Z0830 #JavaCertification #OCP21 #TypePromotion #JavaArithmetic #OperatorPrecedence #JavaCasting #JavaWidening #JavaNarrowing #CompoundAssignment #JavaCompileError #JavaProgramming #OracleJavaCertification #JavaLearn #ClusterMicro #JavaExam #JavaInterview
