Getting Started with Java

Introduction

Popularity: One of the top three programming languages.
Flexibility: Used in various domains including enterprises, Android apps, and games.
Job Opportunities: Java developers have starting salaries around $70,000.

Spectrum of Languages: High-level vs. low-level languages.
Machine Code: Low-level format understood by machines (binary).
Source Code: Human-readable format that compiles to machine code.
Java Source Code: Ends with .java file extension.
Bytecode: Java compiles source code to bytecode, which is cross-platform and ends with .class file extension.

JDK: Contains tools for developers, including the Java Runtime Environment (JRE) and Java Virtual Machine (JVM).
Downloading JDK: Find the appropriate version for your OS.

Creating a Project: Open Eclipse, create a new Java project.
Adding a Class: Create a class with the public static void main method.
Writing Code: Use System.out.print and System.out.println to print to the console.
- Difference: print does not move to the next line; println does.
Escape Sequences: Used for special characters (e.g., \n for new line).
Comments: Use // for single-line comments and /* ... */ for multi-line comments.

Change IDE color scheme for better visibility.
Use shortcuts like sysout for print statements.
Utilize find and replace features to edit code efficiently.
Adding spaces does not affect code execution, but be mindful of where they are used.
Use keyboard shortcuts for zooming in and out.
Restore closed views in the IDE easily.
