    public void setAge(int age) {
        this.age = age;
    }

    public double getscore() {
        return score;
    }

    public void setscore(double score) {
        this.score = score;
    }

    public Date getBirthday() {
        return birthday;
    }

    public void setBirthday(Date birthday) {
        this.birthday = birthday;
    }

    @Override
    public String toString() {
        return "User{" +
                "name='" + name + '\'' +
                ", age=" + age +
                ", score=" + score +
                ", birthday=" + birthday +
                '}';
    }
}

异常原因

因为 User 的 score 属性的 set,get 防范书写不规范, 所以导致获取不到值, 将方法名改为 setScoregetScore 即可
