Back end Track

Week 1 Overview

Welcome to the backend track!

This is the first week of your journey to become a backend developer. Since we will be using Java in the backend track, the first two weeks will be dedicated to learning and getting started with the Java programming language.

You've already learned many programming fundamentals during the core program like variables, functions, loops, arrays, and working with data. Many of these concepts exist in Java too, but Java works quite differently under the hood: it is a compiled, statically typed language. This means you'll need to think about types more explicitly and get familiar with a new development workflow. Some things will feel familiar, others will be genuinely new.

Learning goals

• Set up your Java development environment
• Write and run your first CLI applications in Java
• Understand Java's basic syntax: variables, methods, and control flow
• Work with Java's type system and understand how it differs from JavaScript
• Use arrays and collections to store and manipulate data
• Create simple classes and objects as an introduction to OOP
