Last condition not met while local test cases all passed I tested on my computer with my own tests like: Case 1: world?me,lol,world => return 2 Case 2: world.ok.world.wor32.wor0x:world => return 3 It says "Determine why 'world' appears more than it exists" I don't want to use the solution that CodeGym provides. Too complex.

Java Core, Level 2, Lesson 12

Swimming Pegasus Confusing myself about why swimming Pegasus needs to be abstract. It thought an abstract class would be generally further up the chain eg an animal instead of a horse. Swimming Pegasus seems very specific to be something that's abstract.
