class Student{
   static int counter = 0;
   static String name = "爱情公寓0";
   static{
       System.out.println(counter+" "+name+" ");
       name = "爱情公寓1";
       counter++;
       System.out.println(counter+" "+name+" ");
   }
   {
       System.out.println(counter+" "+name+" ");
       name = "爱情公寓2";
       counter++;
       System.out.println(counter+" "+name+" ");
   }
   Student(){
       System.out.println(counter+" "+name+" ");
       name = "爱情公寓3";
       counter++;
       System.out.println(counter+" "+name+" ");
   }

}
public class Demo{
   public static void main(String[] args){
       System.out.println(Student.counter+" "+Student.name);
       Student student = new Student();
       System.out.println(Student.counter+" "+student.name);
       System.out.println("==============================");
   }
}
