java的多态

public class Fu {
String num = "fu";
static String  age ="fu static";
void show() {
System.out.println("fu  show  ");
}

static void method() {
System.out.println("fu  static  method ");
}
}

public class Zi extends  Fu {
String num = "zi";
static String  age ="zi static";
void show() {
System.out.println("zi  show  ");
}

static void method() {
System.out.println("zi  static  method ");
}
public static void main(String[] args) {
Fu f =new  Zi();
System.out.println(f.num);
System.out.println(f.age);
f.show();
f.method();

}

}
