Recommended Starting Age: 10 years and above
Difficulty Level: Moderate (3 out of 5 on a scale where 1 is the easiest and 5 is the hardest)
Lesson 1: Introduction to Java
Learn about the genesis of Java, its creators, and the reasons for its widespread adoption. Understand the concept of a platform-independent language and why Java is considered as such. Get familiar with the Java Development Kit (JDK) and the Integrated Development Environment (IDE). Install JDK and set up an IDE (like Eclipse or IntelliJ IDEA) on your computer.
Lesson 2: Basic Syntax and Variables
Dive into the building blocks of Java programming - identifiers, keywords, data types, and variables. Understand how to declare, initialize, and use variables. Learn about different data types in Java such as int, float, char, boolean, etc. Practice writing simple Java programs and understand Java syntax.
Lesson 3: Operators and Control Flow Statements
Explore arithmetic, relational, bitwise, logical, and assignment operators. Understand how to use these operators in mathematical and logical operations. Learn about control flow statements which guide the execution flow of programs, including if, else if, else, switch, while, do-while, and for.
Lesson 4: Arrays and Strings
Understand what arrays are and how they can be used to store multiple values of the same type. Learn about multidimensional arrays. Discover Strings in Java, how they are different from other data types, and how to manipulate strings using various methods.
Lesson 5: Methods and Functions
Understand the concept of methods in Java, how to declare them, and how to use them. Learn about function overloading and how it increases the readability of the program. Discover built-in Java methods and how to use them in your programs.
Lesson 6: Object-Oriented Programming - Part 1
Dive into the basics of Object-Oriented Programming (OOP) in Java. Understand what classes and objects are, how to create them, and how to use them. Learn about inheritance, which allows one class to inherit the features of another class, and polymorphism, which allows one interface to be used for a general class of actions.
Lesson 7: Object-Oriented Programming - Part 2
Continue exploring OOP with concepts like encapsulation, which is about binding the data and the functions that manipulate the data into a single unit, and abstraction, which hides the complex details and shows only the functionality. Learn about interfaces, which are a way to achieve abstraction, and packages in Java, which help in grouping related classes, interfaces, and sub-packages for better modularity and maintenance.
Lesson 8: Exception Handling and File I/O
Discover how to handle errors in Java using try, catch, and finally blocks. Understand different types of exceptions and how to create custom exceptions. Dive into File Input/Output (I/O) operations, learning how to read from and write to files in Java.
Lesson 9: Java Libraries and Frameworks
Get introduced to popular Java libraries and frameworks, such as Apache Commons, Google Guava, Spring Framework, and Hibernate. Understand how these libraries and frameworks can simplify and speed up Java development. Learn how to incorporate external libraries in your projects.
Lesson 10: Building a Mini Project
In the final lesson, apply all the concepts learned throughout this course by building a simple Java project. This could be a small console-based application like a calculator or a to-do list. This project will help reinforce the concepts learned throughout the course and give a sense of how everything fits together in a full-fledged application.
