编写一个程序，展示无论你创建了某个特定类的多少个对象，这个类的某个特定的static成员变量只有一个属性。

public class Day6{
public static void main (String [] args){
Student.Setcountry("中国");
Student person1 = new Student("胡图图",3);
Student person2 = new Student("大头儿子",3);
person1.getInfo();
person2.getInfo();
}
}
class Student{
private String name;
private int age;
private static String country;
public Student (String name,int age){
this.name = name;
this.age =age;
}
public void setname(String name){
this.name = name;
}
public String getname(){
return name;
}
public void setage(int age){
this.age = age;
}
public int getage(){
return age;
}
public static void Setcountry(String c){
country = c;
}
public void getInfo(){
System.out.println("姓名为:"+this.name+",年龄为:"+this.age+",国籍为:"+this.country);
}
}
