一个最基础的Java类（狗吃狗粮的代码）

class Dog {

public String name;

public int age;

public void eat() {

System.out.println(name + "吃狗粮");

}

}

public class test {

public static void main(String[] args) {

Dog dog = new Dog();

dog.name = "小黑";

dog.age = 1;

dog.eat();

System.out.println(dog.name);

System.out.println(dog.age);

System.out.println("----------");

Dog dog2 = new Dog();

dog.name = "小黄";

dog.age = 1;

dog.eat();

System.out.println(dog.name);

System.out.println(dog.age);

}

}
