Answer 1

class Horse {

    private String breed;

    public Horse(String breed) {
        this.breed = breed;
    }

    public String getBreed() {
        return breed;
    }

    public void setBreed(String breed) {
        this.breed = breed;
    }
}



import java.util.ArrayList; 
import java.util.List; 

class HorseTester {

    public static int getBreed(List<Horse> h, String breed) {
        int count = 0;
        for (int i = 0; i < h.size(); i++) {
            if (h.get(i).getBreed().equals(breed)) {
                ++count;
            }
        }
        return count;
    }

    public static void main(String[] args) {
        ArrayList<Horse> horses = new ArrayList<Horse>();
        horses.add(new Horse("breed1"));
        horses.add(new Horse("breed1"));
        horses.add(new Horse("breed2"));
        horses.add(new Horse("breed1"));
        horses.add(new Horse("breed2"));

        System.out.println(getBreed(horses, "breed1"));
    }
}
