+1.	Use an ArrayList to store a list of all animals in the zoo ✔
+2.	Display the details of an individual animal ✔
+3.	Display the details of each animal in an ArrayList ✔
+4.	Generate an ArrayList of all animals of a particular type ✔
+5.	Output “Food required” for all animals in an ArrayList (might be all animals, by be a list from 4) ✔
+6.	Output all animals from a specific environment. ✔
