Java Tutorial Introduction

A practical path from your first program to complete applications

This tutorial is designed for students, self-learners, educators, and programmers moving to Java from another language. It begins with essential syntax and gradually introduces object-oriented programming, file handling, collections, desktop interfaces, database programming, and project development.

01

Learn the Fundamentals

Understand variables, data types, operators, input, conditions, loops, arrays, strings, and methods through small programs you can run immediately.

02

Master Object-Oriented Java

Create classes and objects, then apply encapsulation, inheritance, polymorphism, abstract classes, and interfaces to organise programs properly.

03

Build Real Applications

Progress into files, collections, Java Swing, JDBC, SQLite, CRUD operations, mini projects, and a complete course-management application.

Java Installation and JDK Setup

Prepare your computer for Java development

Follow a guided setup process to install a Java Development Kit, verify the installation, create a project folder, and confirm that the Java compiler and runtime are working.

Step 1

Install the JDK

Download and install a suitable Java Development Kit for your operating system.

  • Select the correct Windows installer
  • Complete the installation wizard
  • Locate the installed JDK folder

Open the JDK installation guide →

Step 2

Verify Java

Use Windows Terminal or Command Prompt to confirm the installation.

  • Run java --version
  • Run javac --version
  • Resolve PATH issues when necessary

See verification instructions →

Step 3

Run a Test Program

Create a simple Java file, compile it, and run it from the terminal.

  • Create HelloJava.java
  • Compile with javac
  • Run with the java command

Create your first program →

Development Environment

Choose Visual Studio Code or IntelliJ IDEA

The tutorial provides setup guidance for both editors. Beginners can start with either environment and use the same Java concepts and project source code.

VS

Visual Studio Code Setup

Install Visual Studio Code, add Java development extensions, create a Java project, run programs, use the integrated terminal, and learn basic debugging.

Set up Java in VS Code →

IJ

IntelliJ IDEA Setup

Install IntelliJ IDEA, select the JDK, create a Java project, understand the project structure, run a class, and use the built-in debugger.

Set up IntelliJ IDEA →

↔

Use the Same Source Code

Standard Java source files can be studied and run in either environment. Project notes explain where additional libraries or database drivers are needed.

Browse the project repositories →
