Data Types and How a Java Program Compiles and Runs

Where you are: Week 0 review > Data types and running Java

This part of the review is three short lessons. Work them in order:

1. How a Java program compiles and runs: source versus bytecode, the javac and java tools, and the three kinds of error.
2. Variables and the primitive types: int, double, boolean, char, and String, and how assignment works.
3. Running Java in VS Code and IntelliJ: opening a project, running a program, and turning off AI completion while learning.

Finish all three before moving on to control flow and iteration.
