老师 父类有带参构造函数 子类构造函数应该怎么写？为什么？

//父类

public abstract class Animal {

private String name;

public Animal(String name) {

super();

this.name = name;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public abstract void play();

}

//子类

public class Dog extends Animal {

//子类带参构造函数是这么写么？为什么这么写 

public Dog(String name) {

super(name);

}

@Override

public void play() {

System.out.println(this.getName()+"在做游戏！");

}

}
