The program is introduced using java 8. And the project has been built initially with Maven.
So first, you need to be sure that maven is already installed and fully configured (with java 8 as java home). I used as apache-maven-3.6.2 in this project and jdk1.8.0_171 and JDK. Second, using command line, execute the following :
mvn package
A new folder of maven called target will be generated after this command. To check the tests please follow this folder : surefire-reports, it contains all the results of testing for each junit class created. This result is also shown when executing in the command line previously. You could also execute the following command after executing the previous one:
mvn test
in the same newly created folder, you will find the assembly for our program: SuperMarket1.0-0.0.1-SNAPSHOT.jar To run the program, and exactly the exemple provided in the problem, please run the following command. It will be without any parameters
java -jar SuperMarket1.0-0.0.1-SNAPSHOT.jar
the output in the line command will be:
And if you want to test with other example, just you need to provide exactly 3 parameters with number type:
java -jar SuperMarket1.0-0.0.1-SNAPSHOT.jar 1 2 3
The order of parameters are standing for: <apple quantity> <orange quantity> <watermelon quantity>
