## Traditional Course Outline
1. Methods - Learn how to build reusable blocks of code using custom methods. Discover how to define your own methods, pass in parameters, and return results. Practice with real examples like calculators and string operations to sharpen your method-writing skills.
2. Control flow - Direct the flow of your code using conditional logic. Use if, else if, and else statements to handle different scenarios, and combine conditions with logical operators like && and ||. Build the kind of branching logic that real-world programs rely on.
3. Loops - Automate repetitive tasks with Java’s powerful loop structures. Write for and while loops, and explore how to iterate through Arrays and Strings. Understand when to use each type of loop and how to control their behavior.
4. Bringing it all together - Bring everything together to create flexible, readable code workflows. Combine methods, loops, and conditionals to tackle practical coding challenges. Practice structuring your logic into reusable components that are easy to understand and maintain.
