JAVA code.

Hi- I need some help with JAVA code.

  • When I select 1 for animal, it’ll ask for which animal. If I select 1 to 3, it works but if I select animal #4 it throws my index error even though it’s within the limit
  • When I select 2 for habitat, it’ll ask for which habitat. Whatever number I select here, it’ll actually end up listing the animal for that index and not the habitat. If I select habitat #3, it’ll through my index error as well even though it’s within the limit

I also need to implement a pop up alert whenever the animal/habit with ***** are selected. The alert needs to display the message without the *****

Monitor.JAVA
