请教大神this继承的问题

Question

public class Test {

static Animal[] animals = new Animal[3];

public static void main(String[] args) {

    animals[0] = new Cat("加菲猫",4);
    animals[1] = new Ya("唐小鸭",2);
    animals[2] = new Shark("小鲨",0);

    Scanner input = new Scanner(System.in);


            System.out.println("动物名字\t\t腿的条数\t\t动物叫");
            for (int i = 0; i < animals.length; i++) {
                System.out.println(animals[i].getName() + "\t\t" +animals[i]. + "\t\t"+ animals[i].print());
            }



            public class Cat extends Animal implements leng {
private int strain;

public Cat(String name, int strain) {
    super(name);
    this.strain = strain;
}


public String print() {
    String speak = "喵喵喵....";
    return speak;
}
为什么引用子类构造并赋值时子类的那个this.strain没有显示值
