CW 01 - Hello World and Git

DUE

The objective of this exercise is to create a java file, add it, commit and push to a remote repository.

  1. In your local machine, go to the folder where your assignments repo was cloned ...../APCSA1/apcsa-assignments-fall-YourUsername/, execute git pull and create a folder classwork.

  2. Create a folder 09_09_hello_world inside the classwork folder.

  3. Write a java file HelloWorld.java that prints the message "Hello World!".

  4. Run git status. What does it show?

  5. To add the new file to the repository, run the following command from the root (top-level, ...../APCSA1/apcsa-assignments-fall-YourUsername/) of your repo, not from inside the classwork folder:

    git add classwork/09_09_hello_world/HelloWorld.java

  6. Run git status again. What does it show this time?

  7. Commit and push the file to your repo.

  8. Go to GitHub, HelloWorld.java should be there.
