The purpose CM307 pose of this project is to give you jar files. I'd like you to of using Blue-J or NetBear you will see how things Project 1 Spring 2020 to give you some experience with packages and CO just use a text editor and the command line instead ans. That way I can give one set of instructions and rk without the details hidden from you. Note: in the following I Wahdows you should use LOwing I have used the UNTX directory separator"/". On caps instead. If you're using windows, "bin" directory of a prompt and type the comman explorer to find the "bin" this: Sing Windows, betore doing the steps below, check to see 11 Cory of java is invour ath environment variable. Open a command Cype the command avar If it doesn't find it, then use Elle Lind the "bin" directory of java. It will look something like C:\Program Files\javaljdkxx\bin Next, type "environment Cype "environment" in the search box on the lower left and click on the hat says "Envrionment Variables". Click on Path and Edit. Add the path h" to the path variable. Open a new command window and try the "javac" command a end again. It will find the command when the path variable is correct. to "binat says "Enument" in the sea Follow these instructions carefully: 1. Create a subdirectory tree somewhere with the path edu/washburn/cis/ Move to that directory. Create a file called "Factorial.java". Paste the following code into that file: package edu.washburn.cis.; public class Factorial public static long factorial (long n) if(n==0) return 1; else return n*factorial (n-1); 2. Compile the program with the command "javac Factorial.java". 3. Go to the directory where "edu" appears (it may be helpful to open a second command window) and create a jar file with the command: jar-cvf factorial.jar edu Check it with It should create a jar file with your Factorial class in it. the command: jar -tvf factorial.jar which should have output similar to this: 0 Wed Feb 02 09:18:22 CST 2011 META-INF/ 71 Wed Feb 02 09:18:22 CST 2011 META-INF/MANIFEST.ME O Wed Feb 02 09:09:58 CST 2011 edu/ 0 Wed Feb 02 09:10:02 CST 2011 edu/washburn/ Wed Feb 02 09:10:10 CST 2011 edu/washburn/cis/ 0 Wed Feb 02 09:16:36 CST 2011 edu/washburn/cis/zmech! 165 Wed Feb 02 09:16:36 CST 2011 edu/washburn/cis/zmecha 329 Wed Feb 02 09:16:40 CST 2011 edu/washburn/cis/z zmech eau/washburn/cis/zzmech/Factorial.java /washburn/cis/z zmech/Factorial.class 4. After creating the jar file rename the "edu" directory CO This forces the JVM to use the jar file instead of finding the packag thame the "edu" directory to "edu 2". edu" directory tree. unding the package in the 5. Create a driver program to test your Factorial class. your Factorial class. It should use the 105 ImportEmport edu.washburn.cis. Svo last name> ;. The program shou Print out the factorials of the integers through 20. You call the IACCOLE method like this: "Factorial factorialin). Instead of permanently set ng the classpath you can set it on the command line like this: Note: on UNIX/Linux the directory separator character is":"not" . javac -cp.;C:\cm 307\proj01\factorial.jar Project 1Driver.java and java -cp.;C: \cm 307\proj01\factorial.jar Project 1Driver Note: if you make a mistake in your Factorial class or the directory structure then you'll need to recompile the Factorial.java file and create a new jar file. Re-running the jar command will replace the old jar file, but check the timestamp on the file to be sure. Turn in a copy of your driver source code and output.
