Exercise - Selections

Time for another exercise.

Your task:

• Add a new function boolean isInPackage() to ModelClass_c.java. The function shall return true if the parent of the class is a Package, otherwise it shall return false.
• Write the necessary OAL selection as a comment inside this operation, then write the actual implementation in Java.
• Call the new isInPackage() from ModelClass_c.setKey_lett()
• Build
• Run the xtUML Editor Application in debug mode. Show via breakpoint and stepping that the function successfully returns true for a class inside a package.
