Become an intermediate level Java developer, ready to take on your own projects.

Become a Spring Boot Developer

Learn Java for free with this interactive module, and get a handle on one of the most popular programming languages in the world.

You'll start with a simple hello world program and proceed to cover common concepts such as conditional statements, loop statements, math, and logic in Java, before moving on to more advanced concepts like inheritance, generics, and ArrayLists, along with much more.

Core Java Concepts

## Who is this module for?

This module is designed for anyone who wants to become familiar with the basics of Java and intends to enhance their knowledge and understanding of this language.


## Module structure

This module contains ten main chapters, namely:

1. __Variable and User Input__

   This chapter teaches us how to declare variables with different data types.

2. __Simple Maths & Logic__

   This chapter teaches us some basic mathematical functions in Java. Some coding exercises are also provided, at the end of this chapter, for practice purposes.


3. __Strings and String Processing__

   This chapter provides us with basic information on Java strings and Java methods that are designed for manipulation of strings. 

4. __Conditional Statements__

   This chapter explains how `if` and `switch` statements are used to monitor the flow of program execution.

5. __Loops__

    This chapter explains how `while` and `for` loops are used in a Java program. Some coding exercises are also provided, at the end of this chapter, for practice purposes.
 
6. __Methods__

   This chapter provides detailed information on how to define a method. We will also learn about different types of methods available in Java.

7. __Arrays__

   This chapter explains the basic data structure, i.e., array. In this chapter, we will learn how to use 1-D and 2-D arrays. Some coding exercises are also provided, at the end of this chapter, for practice purposes.

8. __Classes and Inheritance__

    This chapter explains the usage of classes in Java programming. We will also learn how to inherit one class from another.

9. __Generics__

   This chapter provides basic information on generics and a generic class.

 
10. __ArrayLists__

     This chapter explains a data structure, i.e., ArrayList. We will learn how to create an object of `ArrayList` data type and with in-built methods supported.
