Mastering Java Basics: Convert Strings, Create Objects, and Take User Input

By JustAcademy – Your Gateway to Industry-Ready Coding Skills

Java is one of the most popular and in-demand programming languages for developers today. Whether you’re new to programming or switching careers, understanding Java basics is a crucial first step. In this article, we’ll break down three fundamental concepts that every aspiring Java developer should know:

✅ 1. Converting String to Integer in Java

Many times, especially when dealing with user input or data from external sources, you receive values as strings. But what if you need to perform a calculation or logic that requires a number?

Java provides a simple and efficient way to convert a string into an integer using built-in methods. This allows you to take string-based input and use it for arithmetic or decision-making processes.

✅ 2. Creating Objects in Java

Java is an object-oriented programming language, which means everything revolves around classes and objects.

Creating an object means you're making an instance of a class. Once the object is created, you can access its variables and methods to perform operations. This is a key part of structuring real-world applications.

✅ 3. Getting User Input in Java

Want to make your application interactive? Java has built-in support for receiving user input via the console.

Using standard input methods, you can prompt users to enter data like their name, age, or preferences, and then use that data in your program. This is essential for building dynamic and engaging applications.
