package staticer;

}

}

static void die()
{

System.out.println(total);
System.out.println("死人了");
}
static void destroy()
{

System.out.println(total);
System.out.println("人类毁灭了");
}
}
public class staticer {
public static void main(String[] args) {
System.out.println(person.total);
person p=new person();
p.age=15;
p.height=170;
p.name="fdfsds";
System.out.println(p.total);
person p1=new person(11,167,"liming");
System.out.println(p1.total);
p1.die();
p1.destroy();
}
}
结果如下
5
6
7
6
死人了
0
人类毁灭了
