根据sql语句create table quizquestion ( id int primary key auto_increment, quizid int references quiz(id), # 测验标识 questionid int references question(id), #题目标识 weight int, # 分值或权重,用于计算成绩,最终成绩=做对题目权重和/权重总和*100 num int #序号,组卷时的顺序号;如果不随机显示题目顺序,按此序号升序显示每个题目 ); 写出 java实体类

以下是Java实体类的代码示例:
```
public class QuizQuestion {
private int id;
private int quizId;
private int questionId;
private int weight;
private int num;
public QuizQuestion() {
}
public QuizQuestion(int id, int quizId, int questionId, int weight, int num) {
this.id = id;
this.quizId = quizId;
this.questionId = questionId;
this.weight = weight;
this.num = num;
}
// getters and setters
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public int getQuizId() {
return quizId;
}
public void setQuizId(int quizId) {
this.quizId = quizId;
}
public int getQuestionId() {
return questionId;
}
public void setQuestionId(int questionId) {
this.questionId = questionId;
}
public int getWeight() {
return weight;
}
public void setWeight(int weight) {
this.weight = weight;
}
public int getNum() {
return num;
}
public void setNum(int num) {
this.num = num;
}
}
```
这个实体类对应了quizquestion表中的每个字段,每个字段都有对应的getter和setter方法,用于获取和设置字段的值。在构造函数中也包含了每个字段的参数。
