Как решить через статические переменные?

ь

public static void main(String[] args) {
        Solution solution = new Solution();
        for(int y=0; y<50000; y++){
            solution.new Cat();
            solution.new Dog();
        }
    }

public class Solution {
    public static void main(String[] args) {

        for (int i = 0; i < 50000; i++){
            new Cat();
            new Dog();//напишите тут ваш код
    }
}

class Cat {
    @Override
    protected void finalize() throws Throwable {
        super.finalize();
        System.out.println("Cat was destroyed");
    }
}

class Dog {
    @Override
    protected void finalize() throws Throwable {
        super.finalize();
        System.out.println("Dog was destroyed");
    }
}}
