**课程名称：Java 核心全攻略：从零开始学习编程** **课程概述：** 本课程专为零编程基础的初学者设计，旨在全面讲解Java的核心概念，从基础知识到高级技巧，并通过大量的实际示例和编码练习帮助学员掌握。讲师主张以示例驱动的教学方式，全程无PPT，而是通过真实的场景来阐释Java的各项概念，确保学习的实用性和趣味性。学员可以在每个视频下方提出问题，讲师会一一进行解答。课程大纲详细列出了各章节内容，学员亦可提出未涵盖的Java核心概念，讲师会考虑加入。 **课程大纲亮点：** * **Java基础：** JDK与Eclipse安装、Hello World、基本数据类型、‘var’关键字、各种运算符、条件语句（if）、循环语句（for, while, do-while）、循环控制（break, continue）。 * **字符串操作：** 字符串基础、比较、搜索、截取、替换、转换等。 * **面向对象编程（OOPS）：** 类与对象、方法、方法重载、访问修饰符、构造器、数据封装、static关键字、main方法、类与对象进阶练习。 * **继承与多态：** 类继承、方法重写、多态、super关键字、super类构造器、protected访问、抽象类、接口（Interface）、final关键字。 * **数据结构：** 数组（一维、二维、对象数组）、ArrayList、LinkedList、List Iterator、Set（HashSet, LinkedHashSet, TreeSet）及其遍历、Map（HashMap, TreeMap）及其遍历。 * **正则表达式 (RegEx)：** 正则表达式介绍、量词、字符类、括号表达式、OR、DOT运算符、贪婪与懒惰匹配，以及数字范围的正则表达式。 * **异常处理：** 异常概念、Error vs Exception、Checked vs Unchecked Exceptions、throws声明、try-catch-finally块。 * **日期与时间操作 (Java 8+)：** 本地日期时间、自定义日期时间、未来与过去日期时间操作、日期时间差计算、日期时间格式化。 * **特殊类：** Math类、StringBuilder类（及其方法）、Scanner类、Random类、UUID类。 * **文件系统操作：** 读取、编辑文本文件、使用Apache Commons IO、复制移动文件、使用Apache POI读写Excel文件。 * **面试题：** 课程包含面试高频问题。 **学习建议：** 1. **每日投入：** 每天安排30-45分钟，持续学习5天。 2. **分段学习：** 视频时长均在20分钟以内，建议每天观看2-3个视频。 3. **动手实践：** 课程重点在于动手练习，观看后立即尝试代码。 4. **完成作业：** 认真完成随堂练习和作业，并核对答案。 5. **积极提问：** 遇到问题随时提问，讲师会及时解答。 **观看建议：** 为获得最佳观看体验，请根据网络速度调整视频分辨率至720p或1080p。
Hi Friends, this course is specially designed for students who do not have prior coding experience. Course covers all the Core Java Concepts from basic to advanced levels along with practical examples and coding exercises.This course covers Core Java topics in detail from basic to advanced levels. I believe in example-oriented teaching. So, you won't find any PPTs during the sessions. But, you will find dozens of real time scenarios used to elaborate Java basic and advanced concepts.Feel free to post your questions/feedback in the block provided under each session-video. I will make sure that all of your queries are addressed. ‘Course Outline' below will give you a good idea about the depth and the overall coverage of this course. If you want to learn any other Core Java concept - which is not already covered in this course - then feel free to let me know via Udemy messenger.Course Outline:Java BasicsJDK 10 and Eclipse InstallationHello World Java ProgramPrimitive Data Types in Java'var' keyword in Java 10Arithmetic Operators in JavaLogical and Bitwise Operators in JavaRelational Operators in JavaIf - Condition in JavaNested If - Condition in JavaFor Loop in JavaHands-On Exercises on 'For Loop'Nested For Loop in JavaHands-On Exercises on 'Nested For Loop''While' & 'Do While' Loop in JavaLoop 'Break' & 'Continue' Statements in JavaString Basics in JavaString Comparison Operations in JavaString Search Operations in JavaString (Cut) Slice Operations in JavaString Replace Operations in JavaString Conversion Operations in JavaObject Oriented Programing (OOPS) in JavaConcept of Classes and Objects in JavaHands on exercises on Class and ObjectMethods in JavaMethod Overloading in JavaAccess Specifiers (Access Modifiers) in JavaConstructor in JavaData Encapsulation in JavaStatic Keyword in JavaConcept of Main Method in JavaClass and Object Advanced ExercisesClass Inheritance in JavaMethod Overriding in JavaPolymorphism in JavaSuper Keyword in JavaSuper Class Constructor in JavaProtected Access in JavaAbstraction in JavaInterfaces in Java (Java Interface)Final Keyword in JavaData Structures in JavaArrays in JavaArray Object in JavaEnhanced (Modified) For Loop for Array Iteration in JavaHands-on Exercises on Array in Java2-Dimensional Arrays in JavaHands-on Exercise on 2D Arrays in JavaArray of Object in JavaArray List in Java (ArrayList)Structure of ArrayList in JavaLinked List in Java (LinkedList)ArrayList vs LinkedList in JavaList Iterator in JavaHash Set in JavaLinked Hash Set in JavaTree Set in JavaIterating on Set in JavaHash Map in JavaTree Map in JavaIterating Over Maps in JavaRegular Expressions in JavaIntroduction to RegEx in JavaQuantifiers in Regular ExpressionsCharacter Classes in Regular ExpressionsBracket ExpressionsOR Operator in RegEXDOT Operator in RegEXGreedy and Lazy MatchingHands-on Exercises on Regular ExpressionsRegularizing Number RangesException Handling in JavaWhat is an Exception in Java?Error vs Exception in JavaChecked and Unchecked Exceptions in JavaThrows Declaration in JavaTry and Catch Block (Exception Handling) in Java'Finally' Block in JavaDate and Time Operations (Revised in Java 8)Local Date and Time Operations in JavaCustom Date and Time Operations in JavaFuture and Past Date Operations in JavaFuture and Past Time Operations in JavaDate Difference Calculation in JavaTime Difference Calculation in JavaDateTime Formatter in JavaSpecial Classes in JavaMath Class in JavaStringBuilder Class in JavaStringBuilder Methods in JavaScanner Class in JavaRandom Class (for creating random numbers) in JavaUUID Class in Java (for creating universally unique string IDs)Working with File System in JavaHow to Read a Text File in Java?Apache Commons IOHow to Edit a Text File in Java?Hands on Exercises with Text Files in JavaCopy and Move (Rename) a Text File in JavaApache POI SetupReading Excel Data in JavaRead Excel Data into a 2 D Array in JavaWrite Data in Excel Sheet in JavaInterview Questions**I will be updating more topics to this outline as per changing trends in technology** To get the maximum benefit from the course, please take a look at following steps explaining 'How to take this course?'Step 1: Schedule 30-45 minutes of your time daily for 5 days a week. 'Continuity' is the key. Step 2: All sessions are divided in small videos of less than 20 minutes. Watch 2-3 videos daily.Step 3: Hands-on exercise is very important. So, immediately try out the programs discussed in the session, on your own. You can download these programs from lecture resources.Step 4: Assignments with answer keys are provided where-ever necessary. Complete the assignments before jumping on to the next sessions.Step 5: If you come across any questions or issues, please feel free to contact me and I will make sure that your queries are resolved.Wish you all a very happy learning.Note: For the best video streaming quality, please adjust the resolution from 'settings' at bottom right-hand corner of video player. Choose 1080p or 720p as per your network speed.
