Такая проверка по сумме обманула валидатор, но она не покрывает вариант с равными суммами. Как улучшить код? 
public class Cat {
    public int age;
    public int weight;
    public int strength;

    public Cat() {
    }

    public boolean fight(Cat anotherCat) {
        //напишите тут ваш код
        int count1 = 0;
        int count2 = 0;

        if (this.weight == anotherCat.weight || this.age == anotherCat.age || this.strength == anotherCat.strength) {
            int sum1 = this.weight+this.age+this.strength;
            int sum2 = anotherCat.weight+anotherCat.age+anotherCat.strength;
            if (sum1>sum2)
                return true;
            else
                return false;
        }
        if (this.weight > anotherCat.weight)

        if (this.weight < anotherCat.weight)
