2. Basic Types, Operations

We have completed a theoretical course, and now the most interesting part begins. In this section, we will familiarize ourselves with the basics of coding, primitive data types, and operations on them. Now your code can perform mathematical tasks and evaluate conditions for further execution. Sounds interesting? Let's start getting acquainted.

3. Loops

In this section, we will familiarize ourselves with various loops such as for, while, and do-while. Loops are essential to any programming language, as they allow us to efficiently iterate over a large amount of data and save significant time. Later on, you will use loops extensively in tasks like sorting, working with arrays, collections, and more. Well then, let's get started.

Increment and Decrement

Infinite Loop (bonus)

Challenge: Factorial

4. Arrays

This section will cover arrays and how to use them correctly. We will learn how to group data into arrays and explore some methods for working with arrays. Arrays are essential to any programming language Java, so let's dive in.

Index Out Of Bounds

Two-Dimentional Array

Iteration In Two-Dimensional Array

5. String

In this section, you will be introduced to a data type called String. Why is there a separate section in the course for this data type? String is a significant data type with many built-in methods and operations. In this course, you will learn about String and StringBuilder, explore their basic methods, and learn how to use strings effectively in Java. So, are you ready to get started?

Backend Development

Hello, future developer!

Welcome to the course on learning backend programming in Java. In this course, you will be introduced to the fundamentals of this programming language.

To begin, let's first understand what backend programming is.

What is Back-End Development?

Backend programming is the programming of the side of an application that the end user doesn't see. While front-end programmers manipulate images and pixels on a webpage, back-end programming is where the magic happens! The responsibilities of a backend programmer include data analysis, business logic development, securing the application against hacking attempts, configuring product payments system, administering the application system, and designing the application's logic.

It's you!

You can be the programmer who configures all the processes in the application. Database connectivity, established communication between different parts of the application, and much more!

Who will you become?

🤩 First, you will become a sought-after programmer who understands the intricacies of web application processes and more;
✨ You'll be able to diversify into various fields and build your career doing what you love;
📚 You don't need a college degree to work in and learn programming! A strong specialist in backend development is worth more than gold!
💸 High salaries for backend developers are no secret! But you're not studying for that, are you?
🪄 You'll be able to work magic in your code that will leave other developers in awe!

Knowledge is what sets us apart from monkeys! So, I suggest you start soaking up knowledge like a vacuum!

Everything was clear?

Thanks for your feedback!
