与胖虎一起学Java day1

[今天学习了 创建类和方法 实现将冰箱打开 把胖虎放进去 把冰箱焊死]

package demobag;

public class Demo1 {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Fridge f1 = new Fridge();
        f1.open();
        Animal fatTiger = new Animal();
        fatTiger.go();
        Fridge.close();
    }
    
}

package demobag;

public class Animal {

    double size=1000;
    public static void  go(){
        System.out.println("胖虎进冰箱");
    }
    
    public static void  out(){
        System.out.println("胖虎出不来");
    }

}

package demobag;

public class Fridge {

    double size;
    
    public static void open(){
        System.out.println("冰箱开了");
    }
    
    public static void close(){
        System.out.println("冰箱焊死了");
    }


}
