Unix/Makefile Homework

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 Vehicless 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 as (Vehicle)Tester.java, where (Vehicle) can be replaced by any of the vehicle class name. Write a Makefile that does the following:

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.

When make or make vehicles is typed in, each vehicle class will be built (ATAT.class, ATST.class, etc.) if the corresponding Java source file has been updated since the last time that class was built.

When make (Vehicle)Tester.class is typed in, the corresponding tester class is built, if (Vehicle).java or (Vehicle)Tester.java has been updated since the last time the tester was built.

When make tests is typed in, all tester classes will be built (ATATTester.class, ATSTTester.class, etc.), if the corresponding Java source file for that tester or the tested vehicle has been updated since the last time the tester was built.

When type in make clean, all class files will be removed.

HINTS:

Declare variables for your classes to try and organize your code

Make sure you understand the relationship between targets and dependencies
