Java OCA 1Z0-808 | 2.2b Type Casting & Conversions | Widening, Narrowing, Overflow & Exam Traps

Master Type Casting and Conversions for the Oracle Certified Associate Java SE 8 (1Z0-808) exam. In this video (Part B), we cover: ✅ Default Values vs Local Variables — who gets defaults and who doesn't ✅ Type Casting Overview — Widening vs Narrowing ✅ Implicit Casting (Widening) — byte → short → int → long → float → double ✅ Explicit Casting (Narrowing) — why you need the cast operator ✅ char to int and int to char casting ✅ Byte Overflow — what happens when 130 is cast to byte (-126!) ✅ The overflow wrapping pattern explained with examples ✅ Common Compile-Time Errors — double to int, missing L suffix, missing f suffix ✅ boolean cannot be cast to any number — if(1) is ILLEGAL in Java ✅ Practice questions at the end Part A (previous video) covered: → What is a Variable, Declaration vs Initialization → Multiple Declarations on One Line → All 8 Primitive Data Types with Size, Range, Defaults → Float vs Double Precision → Literal Suffixes — L for long, f for float This is Objective 2 of the OCA exam: "Working with Java Data Types — Declare and initialize variables including casting of primitive data types." 📌 Part of our complete Java OCA 1Z0-808 series ✅ Completed: Chapter 1 — Java Basics 1.1 Java Class Structure —    • Java OCA 1Z0 808 1 1 Java Class Structure   1.2 The main() Method —    • Java OCA 1Z0 808 1 2 main Method   1.3 Scope of Variables —    • Java OCA 1Z0-808 | 1.3 Define the Scope of...   1.4 Packages & Imports —    • Java OCA 1Z0-808 | 1.4 Packages & Imports ...   1.5 Java Features —    • Java OCA 1Z0-808 | 1.5 Java Features | Pla...   ✅ Chapter 2 — Working with Java Data Types 2.1 Identifiers & Naming Conventions —    • Master Java Identifiers & Naming Conventio...   2.2a Variables & Primitive Types —   • Java OCA 1Z0-808 | 2.2a Variables & Primit...   2.2b Type Casting & Conversions —    • Java OCA 1Z0-808 | 2.2b Type Casting & Con...   ← THIS VIDEO 2.3 Object References & Object Lifecycle -    • Java OCA 1Z0-808 | 2.3 Object References v...   2.4 Wrapper Classes — Coming Next (Final YouTube Video!) 🔗 Practice with 1,624+ questions: https://javalearn.clustermicro.com 🎁 Free 30-question trial — no credit card needed #Java #OCA #1Z0808 #JavaCertification #JavaCasting #TypeCasting #Widening #Narrowing #JavaOverflow #OracleJava #JavaSE8 #JavaExam #JavaTutorial #JavaBasics #JavaOCA8 #ImplicitCasting #ExplicitCasting #ByteOverflow #JavaDataTypes
