Answer 1

You can't run your code without main method.

public class Fish{

//your Fish class

}

:
//TestFish which works with the Fish class
public class TestFish{

public static void main(String[] args){

//Here you can create Fish objects and see if all methods works

//Fish amber and Fish james goes here

}
