面向对象具体实例Pet

package oop.demo03;

public class Pet {
public String name;
public int age;

public void shout(){
System.out.println("叫了一声");
}
}

/*
public static void main(String[] args) {
Pet dog = new Pet();
dog.age= 3;
dog.name="77";
dog.shout();

System.out.println(dog.name);
System.out.println(dog.age);

}
*/
