Java Tutorial

Welcome to The Coding College, your ultimate destination for learning programming and coding skills. In this tutorial, we’ll dive into the fundamentals of Java, one of the most popular and versatile programming languages in the world. Whether you’re a beginner or looking to enhance your programming skills, this guide will provide valuable insights to help you get started with Java.

What is Java?

Java is a high-level, object-oriented programming language developed by Sun Microsystems (now owned by Oracle). Known for its platform independence, Java programs are written once and can run anywhere, thanks to the Java Virtual Machine (JVM).

Key Features of Java:

  • Platform-Independent: Write once, run anywhere (WORA).
  • Object-Oriented: Encourages modular and reusable code.
  • Robust: Built-in garbage collection and strong memory management.
  • Secure: Advanced security features for application development.
  • Multi-Threaded: Supports concurrent processing.

Why Learn Java?

Java is an essential language for developers because:

  1. Industry Demand: Widely used in web development, Android apps, enterprise software, and more.
  2. Ease of Learning: Beginner-friendly syntax and vast community support.
  3. Job Opportunities: High demand for Java developers across various industries.
  4. Versatility: From small-scale applications to complex systems, Java handles it all.

Setting Up Your Environment

To start coding in Java, follow these steps:

  1. Download and Install Java Development Kit (JDK):
    Visit Oracle’s official website to download the latest version of JDK.
  2. Set Up an Integrated Development Environment (IDE):
    Popular IDEs include:
    • Eclipse
    • IntelliJ IDEA
    • NetBeans
  3. Write Your First Program:
    Use your IDE or a simple text editor to write a “Hello World” program: 
public class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello, World!");
    }
}
  1. Compile and Run:
    • Save the file as HelloWorld.java.
    • Open the terminal, navigate to the file location, and run: 
javac HelloWorld.java
java HelloWorld

Core Concepts in Java

1. Data Types and Variables

Java supports various data types, including:

  • Primitive: int, char, float, double, boolean, etc.
  • Non-Primitive: Strings, Arrays, Classes, and Objects.

Example:

int age = 25;  
String name = "John";  
boolean isStudent = true;

2. Control Structures

  • Conditional Statements: if, else, switch
  • Loops: for, while, do-while

Example:

for (int i = 0; i < 5; i++) {  
    System.out.println("Count: " + i);  
}

3. Object-Oriented Programming (OOP)

Java’s OOP principles include:

  • Encapsulation
  • Inheritance
  • Polymorphism
  • Abstraction

Example:

class Animal {  
    void sound() {  
        System.out.println("Animal makes a sound");  
    }  
}  

class Dog extends Animal {  
    void sound() {  
        System.out.println("Dog barks");  
    }  
}
