Assignment #3 (due 10/11/01 within 10 minutes of the lecture class); three sample Java programs (the third added 10/03) are Employee.java, SampleEmployee.java, and TestTokens.java (added 10/03). Three input files that contain sample inputs for testing your program (added 10/03) are input1.txt, input2.txt (revised on 10/05, 11:50 pm), and input3.txt. (Added 10/07/2001) Concerning the end of keyboard input, the jdk users should read jdkReadme.txt; the JBuilder users should read JBuilderReadme.txt;

Assignment #3 solution keys (posted 10/13): the Boss.java class; the HourlyWorker class; and the TestEmployee class (the one that has a main()); and the 3 output files (including the prompt on the screen) when running the respective input files: output1.txt; output2.txt; and output3.txt. The grading of the assignment is based on this grading sheet, using 3 new input files input4.txt; input5.txt; and input6.txt.

Assignment #4 (posted 10/16, due 10/25 in class): some sample java files demonstrating the use of interfaces are Employee.java; Compare.java; CompareBoss.java; SortPrint.java; ArrOfBosses.java; and DemoBoss.java. A smaple input file is input.txt, the corresponding output file is output.txt. Two sample programs posted 10/18 demonstrating the use of Vector and File I/O, and command-line arguments, are TestFileIO.java and Arguments.java. You also need to use the following two files from Assignment 3's solutions: Boss.java; and HourlyWorker.java.

Assignment #4 solution keys (posted 10/28): the SortOutput interface; the SortedEmployees class; and the TestSortedEmployees class. The grading of the assignment is based on this grading sheet.
