**Course Introduction**
- Instructor: Mosh, a software engineer with 20 years of experience.
- Course goal: Teach Java programming from basics to advanced features.
- Designed for beginners; no prior experience required.
- Emphasis on writing professional-quality code.
- Over 3 million students taught through Mosh's coding school.
**Course Structure**
- Installation of necessary tools (Java Development Kit and IntelliJ).
- Basics of Java programming, including:
- Code execution process.
- Building simple algorithms.
- Writing clean and maintainable code.
- Final project: Build a mortgage calculator.
- Future sections will cover:
- Object-oriented programming.
- Core Java APIs.
- Advanced Java features (streams, threads, database programming).
**Java Development Kit (JDK) Installation**
- Search for "JDK download" in a browser.
- Download appropriate version for your operating system (Windows, Mac, Linux).
- Accept license agreement and install the JDK.
- Install a code editor (IntelliJ IDEA recommended).
**Anatomy of a Java Program**
- Functions: Basic building blocks that perform tasks.
- Main function: Entry point of every Java program.
- Classes: Containers for related functions (methods).
- Access modifiers: Control visibility of classes and methods (e.g., public, private).
- Naming conventions: Pascal case for classes, camel case for methods.
**Creating Your First Java Project**
- Create a new project in IntelliJ IDEA.
- Set project name and base package.
, - Understand project structure (source folder, package structure).
- Write and execute a simple "Hello World" program.
**Java Code Execution Process**
- Two main steps: Compilation and execution.
- Compilation: Converts Java code to bytecode using the Java compiler.
- Execution: Java Virtual Machine (JVM) translates bytecode to native code for the operating
system.
- Java's platform independence allows code to run on any OS with a JVM.
**Interesting Facts About Java**
- Developed by James Gosling in 1995 at Sun Microsystems.
- Four editions of Java: Standard, Enterprise, Micro, and Card.
- Java is widely used, with millions of developers and applications.
- Average salary for Java developers in the US is over $100,000.
**Course Overview**
- First part focuses on Java fundamentals.
- Subsequent parts cover:
- Type system and data handling.
- Control flow statements and algorithms.
- Clean coding practices.
- Error handling and deployment.
**Variables and Data Types in Java**
- Variables: Used to store data temporarily.
- Primitive types: Simple values (e.g., int, byte, char, boolean).
- Reference types: Complex objects (e.g., classes).
- Naming conventions: Use meaningful names and camel case.
**Strings in Java**
- Strings: Sequence of characters, immutable in Java.
- Common string methods:
- Concatenation, length, indexOf, replace, toLowerCase, toUpperCase, trim.
- Special characters: Use backslash to escape characters (e.g., double quotes, backslashes).
