Course Description

Get Started with Java Programming


Java is one of the most widely used programming languages, powering everything from mobile apps to large-scale enterprise systems. If you are looking to build a strong foundation in Java, this course is the perfect place to start. You will learn how Java works, write your first lines of code, and explore essential programming concepts step by step.

Understand Java Syntax and Work with Data


Begin with the basics by running a simple Java program and understanding how Java organizes its code. Learn about variables and data types like numbers, text, and boolean values, and see how Java stores and processes information. By the end of this section, you will be comfortable working with different types of data in Java.

Perform Calculations and Compare Values


Programming often involves working with numbers and making decisions based on conditions. In this course, you will use arithmetic operators to perform calculations and comparison operators to evaluate expressions. These skills will help you write dynamic programs that respond to different inputs and conditions.

Build a Solid Java Foundation


By the end of this course, you will have a clear understanding of Java’s core concepts, including syntax, variables, and operators. With hands-on coding exercises, you will gain the confidence to start writing your own Java programs and take the next step in your learning journey.
