Java OCA 1Z0-808 | 2.2a Variables & Primitive Data Types | Declaration, 8 Types, Literals & Suffixes

Master Java Variables and Primitive Data Types for the Oracle Certified Associate Java SE 8 (1Z0-808) exam. In this video (Part A), we cover: ✅ What is a Variable? — Type, Name, Value ✅ Declaration vs Initialization — the critical difference ✅ Multiple Declarations on One Line — the int a, b = 5 trap ✅ All 8 Primitive Data Types — byte, short, int, long, float, double, char, boolean ✅ Size, Range, and Default Values table ✅ Float vs Double Precision — ~7 digits vs ~15 digits explained ✅ Literal Suffixes — why long needs L and float needs f Part B (next video) will cover: → Default Values vs Local Variables → Type Casting Overview → (implicit / Explicit casting) Widening & Narrowing → Byte Overflow → Common Casting Compile-Time Errors → Practice Questions 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...   ← THIS VIDEO 2.2b Type Casting & Conversions —    • Java OCA 1Z0-808 | 2.2b Type Casting & Con...   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 #JavaVariables #PrimitiveTypes #JavaDataTypes #OracleJava #JavaSE8 #JavaExam #JavaTutorial #JavaBasics #JavaOCA8 #JavaFloat #JavaDouble #JavaLiterals #ByteShortIntLong
