有一个学生类的结构如下：
class Student {
    private int no;
    private String name;
        private int score;
    
    public Student(int _no, String _name, int _score) {
        no = _no;
        name = _name;
                score = _score;
    }
        public int getNo() {return no;}
        public String getName() {return name;}
        public int getScore() {return score;}
    
    public void print(){
        System.out.println(no + " "+name+" "+score);
    }
}

请构造main函数完成如下功能：
