Java一个很基础的面试题【求助】

Question

 public class Apple extends Fruit  {
    private String name = "apple";
    public Apple () {
        tellName();
        printName();
    }
    public void tellName() {
        System.out.println("Apple tell name: " + name);
    }
    public void printName() {
        System.out.println("Apple print name: " + name);
    }
    public static void main(String[] args){
        new Apple();    
    }
}
class Fruit {
    private String name = "fruit";
    public Fruit () {
        tellName();
        printName();
    }
    public void tellName() {
        System.out.println("fruit tell name: " + name);
    }
    public void printName() {
        System.out.println("fruit print name: " + name);
    }
}

我想知道为什么会输出4行
以及什么原因
感谢各位
