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.

- Assess short Java code segments to predict their printed output and resulting data types.
- Differentiate between arithmetic operators (+, -, *, /, ++, --) and comparison operators (>, <, >=, <=, ==, !=) when applied in Java expressions
- Distinguish between individual variables and arrays in terms of declaration syntax, indexing, and element mutability
- Identify the required components of a basic Java program, including class declarations, the main method signature, and statement termination
- Recognize which primitive or reference data type should be used to store given numeric, character, boolean, or textual data
Prerequisites
There are no prerequisites for this course1
Java and Programming Basics
Kickstart your Java journey by writing and running your first program. Learn the basics of Java syntax, organize code with classes, and work with variables to store and manipulate data. By the end of this chapter, you will be ready to start coding in Java with confidence!
2
Working with variables
Master the building blocks of data in Java by working with variables and arrays. Explore primitive data types like int, double, boolean, and char, and learn how to store and manipulate text with Strings. Discover how to combine and transform Strings, and get hands-on with arrays to store multiple values efficiently.
3
Operators
Learn how to perform calculations and comparisons in Java using operators. Use arithmetic operators to add, subtract, multiply, divide, and modify numeric values. Then, explore comparison operators to check conditions like greater than, less than, and equality, laying the foundation for decision-making in Java programs.
