Objects containing Objects
practice with Dogs and Kennels

• Download the Dog/Kennel .jar file as seen in lecture. (how-to-get-jar-files-into-BlueJ—Downloading .jar files into BlueJ)
• Create a few Dog objects, and one Kennel object.
• Using BlueJ, inspect the Kennel you created. Double-click on the various Dog fields, to “follow the arrow”.
• Modify Kennels so that in addition to the two Dogs passed to the constructor, every Kennel contains a third "resident" Dog whose name is “Bowser” and is 15 years old.
  Be sure to update the (already-stubbed) getter and setter methods getResidentDog and setResidentDog.
• We have already written a method for Dogs, ageOneYear. Now, write a method for Kennels: oneYearPasses. This is a void method which causes every Dog inside the Kennel to get one year older. Note that javadoc and test cases have already been provided for you; you only need to write the code itself.
• Write the Kennel method averageAge. Note that javadoc and test cases have already been provided for you; you only need to write the code itself.
