声明引用了吗?
给你完整代码
学生类Student，代码如下：
class Student{
private String no;
private String name;
private Integer score;
public String getNo() {
return no;
}
public void setNo(String no) {
this.no = no;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Integer getScore() {
return score;
}
public void setScore(Integer score) {
this.score = score;
}
public String toString(){
return "学号：" + no + " 姓名：" + name + " 成绩：" + score;
}
}
