Your impressive work at your internship has won you a return offer at the Galactic Empire. You were but the student; now you are the master! You are responsible for all Imperial Vehicles's software reliability. The vehicle classes include ATAT.java ATST.java DeathStar.java ImperialShuttle.java StarDestroyer.java . TIEBomber.java TIEFighter.java For each of these classes, there is a Tester class that contains all unit tests for the corresponding vehicle named (Vehicle)Tester.java, where (Vehicle) can be replaced by any of the vehicle class name. Write a Makefile that does the following 1. When make (Vehicle).class is typed in, the corresponding vehicle class is built, only if its Java source file has been updated since the last time it was built. 2. When make or make vehicles is typed in, each vehicle class will be built (ATAT.class, ATST.class, etc.) if the corresponding Java 3. When make (Vehicle)Tester.class is typed in, the corresponding tester class is built, if (Vehicle).java or (Vehicle)Tester.java has 4. When make tests is typed in, all tester classes will be built (ATATTester.class, ATSTTester.class, etc.), if the corresponding Java 5. When type in make clean , all class files will be removed source file has been updated since the last time that class was built. been updated since the last time the tester was built. source file for that tester or the tested vehicle has been updated since the last time the tester was built. HINTS: 1. Declare variables for your classes to try and organize your code 2. Make sure you understand the relationship between targets and dependencies 3. When turning in your code, be sure it is not commented out. We should be able to run the Makefile with the tests above. Remark There are multiple ways to do this assignment! Make sure to test. One common error is that students compile every file when they don't necessarily have to. For example, if we only change DeathStar.java, and we enter "make vehicles," then we should ONLY update DeathStar.class since DeathStar.class file is now the only file out of date. You should NOT be recompiling every single file. Your impressive work at your internship has won you a return offer at the Galactic Empire. You were but the student; now you are the master!
