By now you should know how to create a subdirectory for this assignment, create that subdirectory now and change into that subdirectory. You have been asked to write an interactive program, in Java, to aid in the construction and management of a Space City. To aid in the rapid development of this program, 3 Java files and an example input file are provided for you: CrewMember.java, Module.java, SpaceCity.java and a sample input file mod10.dat Note that CrewMember.java is fully implemented for you. Copy them from the unit library area into your current directory (which will be your newly created subdirectory) using: cp /home/1st/csilib/cse1oof/prog/* . Failure to create a subdirectory and cd into it will result in your java files from Assignment Part C being overwritten by the files for this assignment. Task 1 - Module.java Design and implement the Module class (by completing Module.java) so that we can create and use a Module object.
