the lab is mainly about managing the environment

1. How to run the java codes?

For example, to run HelloWorld.java, we'd type the command javac HelloWorld.java into the terminal, followed by the command java HelloWorld. The result would look something like this:

$ javac HelloWorld.java
$ java HelloWorld
Hello World!

Submitting to Gradescope

  1. Add your assignment directory using git add. For example, for Lab 1, from your repo root (sp24-***) you would use git add lab01. From the assignment directory, you could use git add ..
  2. Commit the files using git commit -m "<commit message here>". The commit message is required. For example, git commit -m "Finished Lab 1".
  3. Push your code to your remote repository with git push origin main.
  4. Open the assignment on Gradescope. Select Github, then your sp24-s*** repository and the main branch, then submit your assignment. You will receive a confirmation email, and the autograder will run automatically.

Gradescope will use the latest version of your code from Github. If you think that Gradescope isn’t grading the right code, check that you have added, committed, and pushed with git status.

Problems:

  • git clone create a new directory which is named the same as the remote repository itself. So after cloning it, make sure to cd cs61b instead of adding branches in the original vault. the fatal message could be: alt text
