Java, being an object-oriented programming language, revolves around the concept of objects and classes. Object-oriented programming (OOP) allows developers to organize code into reusable entities called classes, which encapsulate data and behavior. In Java, objects are instances of classes and can interact with each other through method invocations. Key OOP principles such as inheritance, polymorphism, and encapsulation play a significant role in designing efficient and maintainable backend applications.

2.2 Java Syntax and Control Structures

• Learning the syntax of the Java programming language
• Exploring control structures like conditionals and loops

Java syntax is known for its readability and ease of understanding. Learning the basic syntax, including variable declaration, data types, operators, and control structures, is essential to write functional and efficient Java code. Control structures such as conditionals (if-else statements) and loops (for, while) allow developers to make decisions and iterate over blocks of code based on specific conditions. Mastery of these control structures is crucial for implementing complex backend functionality.

2.3 Working with Data Structures and Collections in Java

• Understanding the various data structures available in Java
• Exploring collections such as arrays, lists, sets, and maps

Data structures are integral to managing and manipulating data effectively. Java provides a rich set of built-in data structures and collections that simplify the manipulation and storage of data. Arrays, lists, sets, and maps are commonly used collections in Java, each offering unique features and functionalities.
