## Learning Outcomes
- 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
## Traditional Course Outline
1. 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.
