1. Introduction to Java
• What is Java?
o Java is a high-level, object-oriented programming language developed by Sun
Microsystems (now owned by Oracle). It is known for its platform
independence and write-once-run-anywhere principle.
• Java's Features
o Simple syntax and easy to learn
o Object-oriented programming (OOP) paradigm
o Platform independence (thanks to the Java Virtual Machine - JVM)
o Robust and secure
o Garbage collection for automatic memory management
o Rich standard library
• Java Development Kit (JDK)
o JDK is a software development kit that provides tools necessary to develop,
compile, and run Java programs.
o It includes the Java Runtime Environment (JRE), the Java compiler (javac),
and other development tools.
• Setting up Java Development Environment
o Download and install the latest JDK for your operating system.
o Set the JAVA_HOME environment variable.
o Add the JDK's bin directory to the system's PATH variable.
o Verify the installation by running java -version in the terminal.
2. Basic Syntax
• Hello World Program
java
• public class HelloWorld {
• public static void main(String[] args) {
• System.out.println("Hello, World!");
• }
• }
•
o Explanation:
▪ public: Access modifier indicating the class is accessible to other
classes.
▪ class: Keyword used to declare a class.
▪ HelloWorld: Name of the class, which should match the filename.
▪ main: The entry point of the program.
▪ String[] args: Command-line arguments passed to the program.
