Welcome to 6.170. You may notice that this Problem Set is some 20-odd pages in length. DON'T PANIC! In view that some of you may be new to Java, we have added quite a few screenshots and detailed instructions so that you will be able to complete this Problem Set with as much help as you need. Most of the problems consist of following instructions to set up the configuration of your Eclipse IDE (Integrated Development Environment) and some simple exercises to help you become familiar with the tools that you will use for the rest of the course. 

For the first problem set only, we encourage you to work in pairs, collaborating as much as you like, without constraint. If you know Java forwards and backwards, feel free to help a fellow student. If Java is all new to you, ask another student for help, along with the LAs, the TAs, and (if you corner them) the lecturers. However, you will submit your problem set and be graded independently. We urge you not to let your buddy "help" you by doing everything for you; this will just make your life harder on the next problem set. 


Initial Setup

You must do this step FIRST, even if you are working from home 

Before doing any work (problem sets, labs, etc.) for 6.170, you need to set up your 6.170 environment on Athena. (Once you set up your environment, you will not need to do it again this semester.) Even if you choose to work from home, you will ultimately be submitting your files on Athena filesystem, so you must perform this step. On dialup, or while logged in at an Athena workstation, type the following commands at your athena% prompt: 

add 6.170

If you see the message 6.170 setup complete, then you are done. You must logout and login again for the changes to take effect. This script will add some lockers and set some environment variables that are required for 6.170. These changes will be documented in your ~/.environment file. If you see an error message when running, then contact the course staff for assistance. 



In this assignment, you will learn how to edit, run and test Java code. We will introduce several tools to help you with these tasks, namely
