static不实现多态

class Father
{
    
    public static String getName()
    {
        return "father";
    }
}

class Children extends Father
{ 
    public static String getName()
    {
        return "children";
    }
}
public class staticTest {
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Father father=new Father();
        Father children=new Children();
        System.out.println(father.getName());
        System.out.println(children.getName());
    }

}

代码中子类和父类都声明为static的函数，注意static不依赖于对象的实例，而依赖于对象，声明对象的时候就分配空间。所以它是依赖于类的，Father children的时候就打印出Father的father.结果为 father  father

去掉static才能实现多态。
