I have three classes called Pokemon.java, Move.java and PokemonTrainer.java which contain methods for creating and modifying Pokemon, their moves and their trainers. I've created all of the required methods, but I'm having issues calling the Pokemon objects that I have created within the PokemonSimulation.java class, the program always fails to compile with the error "java:56: error: cannot find symbol". How can I fix this?
Here is the code for Pokemon.java:
