First action we must take before demonstrating how moving and copying java elements works. Lets create another package called "secondAPP"
After package is created right-click the file "Lab1Exercise.java" under the firstAPP package, scroll down to "Refractor" and click on "Move...". The move window should have open
Select the "secondAPP" package and click OK
If you notice now, the class that was once in the "firstAPP" package is now in the "secondAPP" package and all necessary changes within the code has been made
