Part 3 of this project

Functions

Write and call functions in Java

Runnable lab for this step

This lesson explains the ideas. The matching GitHub folder has runnable examples—clone it, run the file, then tweak it.

Open snapshot on GitHub

fcc-lang-java/03-Functions

Run locally

git clone https://github.com/michaeldunga1/fcc-lang-java.git
cd fcc-lang-java/03-Functions
javac Main.java && java Main

Goal for this part

Write and call functions in Java.

Treat 03-Functions as the source of truth for this checkpoint.

What you should already know

You can open a terminal and edit text files
You have the Java toolchain available
Earlier parts of this course are complete when this is not part 1

Checkpoint

You can explain the goal of this part in one sentence
The snapshot folder README commands complete without mystery errors
You know what changed versus the previous part

Common pitfalls

Running commands from the repo root instead of 03-Functions
Skipping the README prerequisites for this snapshot
Mixing files from a later part into an earlier folder
Moving on before the checkpoint list above is true
