怎样用Java制作一个选择题？

package Work1;public class TestSelect {public static void main(String[] args) {Question question=new Question(1, "（）是拥有属性和方法的实体。", 5, "AB",new Select("A", "对象"), new Select("B", "类"), new Select("C", "方法"), new Select("D", "类的实例"));System.out.println(question.toString());}}

package Work1;public class Question {int num;//序号String timu;//题目double sccore;//分值String answer;//答案Select seA;Select seB;Select seC;Select seD;public Question(int num, String timu, double sccore, String answer, Select se1, Select se2, Select se3,Select se4) {super();this.num = num;this.timu = timu;this.sccore = sccore;this.answer = answer;this.seA = se1;this.seB = se2;this.seC = se3;this.seD = se4;}@Overridepublic String toString() {String tm=num + "、" + timu + "(" + sccore + "分)(答：" + answer + ")";tm+="\n"+seA;tm+="\n"+seB;tm+="\n"+seC;tm+="\n"+seD;return tm;}    
}

package Work1;public class Select {String title;//选项abcdString content;//选项内容public Select(String title, String content) {super();this.title = title;this.content = content;}@Overridepublic String toString() {return title+":"+content;}
}

实现效果
