2 试题与试卷 1)Problem 类Sheet 表中的一行数据是一道试题.用Problem 类来封装 Sheet 表的基本结构,即试题, 这对于后续代码的设计是非常有利的.下列 Problem 类封装表结构,其实例是一道试题. Problem.java package ch5.data;

public class Problem { boolean isChoice;

//是否为选择题 boolean isJudge;

//是否为判断题 String content;

//题目内容 String giveChoiceA,giveChoiceB,giveChoiceC,giveChoiceD;

//提供选择 String imageName;

//题目所带的图像文件的名字 String correctAnswer= QWEQ@#$@!@#1QWEQ ;

//题目的正确答案 //用户回答的初始答案和 correctAnswer 不同,防止出题人忘记给正确答案 String userAnswer = ;

//初始值必须是不含任何字符的串 public boolean getIsChoice() { return isChoice;

} public void setIsChoice(boolean b) { isChoice = b;

} public boolean getIsJudge() { return isJudge;

} public void setIsJudge(boolean b) { isJudge = b;

} public void setContent(String c) { content = c;

} public String getContent() { return content;

} public void setCorrectAnswer(String a) { correctAnswer = a;

} public String getCorrectAnswer() { 第5章标准化试题训练系统

107 return correctAnswer;

} public void setUserAnswer(String u) { userAnswer = u;

} public String getUserAnswer() { return userAnswer;

} public void setGiveChoiceA(String a) { giveChoiceA = a;

} public String getGiveChoiceA() { return giveChoiceA;

} public void setGiveChoiceB(String b) { giveChoiceB = b;

} public String getGiveChoiceB() { return giveChoiceB;

} public void setGiveChoiceC(String c) { giveChoiceC = c;

} public String getGiveChoiceC() { return giveChoiceC;

} public void setGiveChoiceD(String d) { giveChoiceD = d;

} public String getGiveChoiceD() { return giveChoiceD;

} public void setImageName(String c) { imageName = c;

} public String getImageName() { return imageName;

} } 2)TestPaper 类 训练时需要从题库获得若干个试题,即用若干个试题组成一张试卷,这里用 TestPaper 类封装试卷,即该类的实例就是一张试卷. TestPaper.java package ch5.data;

Java 课程设计 第3版108 public class TestPaper { //试卷 private Problem [] problem=null;

//数组的每个单元存放一道试题(一个 Problem 对象) int index = -1;

String problemSource ;

//试卷的题库 public void setProblem(Problem [] problem){ this.problem = problem;

} public Problem getProblem(int i) { if(problem == null) { return null;

} if(problem.length==0){ return null;

} if(i>

=problem.length||ijava ch5.gui.AppWindow AppWindow.java package ch5.gui;

import ch5.data.GiveTestPaper;

import ch5.data.RamdomInitTestPaper;

import ch5.data.TestPaper;

import ch5.data.TeacherOne;

import ch5.view.TestPaperView;

import ch5.view.IntegrationView;

public class AppWindow { public static void main(String []args) { String testName= ;

IntegrationView integrationView = new IntegrationView();

GiveTestPaper initTestPaper = new RamdomInitTestPaper();

Java 课程设计 第3版126 //创建初始试卷对象 TestPaper testPaper= initTestPaper.getTestPaper( 题库/交通理论.xls ,5);

//得到有

5 个题目的试卷 TestPaperView testView = new TestPaperView();

testView.setTestPaper(testPaper);

//设置试卷 testView.setTeacher(new TeacherOne());

//设置阅卷老师 testName = 交通法训练 ;

testView.setTestName(testName);

testView.setTotalTime(15);

//考试时间

15 分钟 integrationView.addTestPaperView(testName,testView);
