package oop;

public class Dog {
String nameString;
int age;
public void info() {
System.out.println("name"+nameString);
System.out.println("age"+age);
}
public void eat() {
System.out.println("吃饭");
}

}

package oop;

public class TestDog {

public static void main(String[] args) {
Dog dog = new Dog();
dog.age=1;
dog.nameString="金毛";
dog.eat();
dog.info();
}

}
