Assignment #1: Tech Jobs Console
Congratulations! Based on your hard work and strong coding skills, you have been brought on as an apprentice to the LaunchCode Tech Team. You will be paired with a mentor to help you get comfortable and continue learning.
The Company Team at LaunchCode works with employer partners to match qualified programmers with apprenticeships. They asked for a new tool to be built to help them easily manage data for currently available jobs. Over the next few weeks, you will help them build this application alongside mentors from the Tech Team.
This first project will be a simple proof-of-concept prototype. It won’t be pretty or have lots of features, but it will give you a chance to work through some initial concepts and get feedback from LaunchCode staff.
Your mentor on this project is Blake.
In this project, you will show that you can:
- Read and understand code written by others.
- Use core Java syntax (methods, variables, loops, conditionals).
- Work with console I/O via the
- Work with data types and arrays.
TechJobs (Console Edition)
The app you must help design is a simple console (i.e. command-line) prototype of the new TechJobs app. It will allow LaunchCode staff to browse and search listings of open jobs by employer partners.
The prototype process gives everybody a chance to work out some initial ideas without investing a ton of time into developing a finished product. Once everybody likes the prototype, the Tech Team will begin work toward a full-fledged application.
Blake created a console application and started to fill in some features. His code allows users to search job listings by one of several fields. It can also display lists of all of the values of a given field in the system (e.g. all employers, or all locations).
Blake has now handed the task off to you. You must add a couple of features and then get feedback from the Company Team.
After you work through the tasks Blake has laid out for you, tackle one or more of the bonus missions .
You may need to enable actions within your github repository if you have not done so already. Please refer back to the instructions on how to do so in the

In Canvas, Graded Assignment #1: TechJobs Console contains a GitHub starter code repo link. Fork the repository to your personal profile, copy the repo’s URL for cloning, and open up IntelliJ. and then set up the project in IntelliJ. Refer back to the setup instructions from assignment 0 for more details.
Before diving in and starting to code, make sure you understand what the code
you’ve been given does. Since you’re starting with a functioning—albeit
unfinished—program, go ahead and run it to get an idea of how it works. To do
this, right-click on the
main method in the
TechJobs class and select
The application will run until you force it to quit, re-prompting time after time. To kill it, press the red “stop” icon in the Run pane or enter
x from the initial prompt. We’ll learn precisely how the program manages to work this way below.
Let’s explore the code by starting with the source of the data our program is providing access to.
