三、我的解题思路

四、具体设计

五、代码说明

1.main（） ``` public static void main(String[] args) { // 命令输入格式检查 if (!ListCommand.checkInput(args)) { System.out.println("命令输入格式错误，退出程序"); System.exit(1); } //初始化命令和数据表 ListCommand aListCommand = new ListCommand(args); Statistic aStatistic = new Statistic(); //检查命令是否符合要求 aListCommand.checkCommand(aStatistic); //初始化日志目录 LogFiles aLogFiles = new LogFiles(aListCommand.arguments[0].value); //读取日志 aLogFiles.readFiles(aListCommand.arguments[2].value, aStatistic); //输出统计结果 aStatistic.outPutFile(aListCommand.arguments[1].value, (TypeArgument) aListCommand.arguments[3], (ProvinceArgument) aListCommand.arguments[4]); //完成 System.out.println("运行成功！统计数据存放在"+aListCommand.arguments[1].value); } ```

2.ListCommand构造函数

ListCommand(String[] strs) {
        // TODO Auto-generated constructor stub
        name = strs[0];
        arguments = new BaseArgument[5];
        arguments[0] = new LogArgument("-log");
        arguments[1] = new OutArgument("-out");
        arguments[2] = new DateArgument("-date");
        arguments[3] = new TypeArgument("-type");
        arguments[4] = new ProvinceArgument("-province");

        // 分析命令行 赋值arguments
        for (int i = 1, k = 0; i < strs.length && k < 5; ++i) {
            int n = 1;
            // 经检查strs[1]一定是参数
            ++i;
            while (!strs[i].startsWith("-")) {
                ++n;
                ++i;
                if (i == strs.length) {
                    break;
                }
            }
            --i;
            // 创建赋值BaseArgument的string数组
            String[] argStrings = new String[n];
            for (int j = 0; j < n; ++j) {
                argStrings[j] = strs[i - n + 1 + j];
            }

            // 赋值BaseArgument[]
            switch (argStrings[0]) {
            case "-log":
                arguments[0] = new LogArgument(argStrings);
                break;
            case "-out":
                arguments[1] = new OutArgument(argStrings);
                break;
            case "-date":
                arguments[2] = new DateArgument(argStrings);
                break;
            case "-type":
                arguments[3] = new TypeArgument(argStrings);
                break;
            case "-province":
                arguments[4] = new ProvinceArgument(argStrings);
                break;
            default:
                ;
            }
        }
    }

3.LogFiles构造函数，其中目录下的日志文件用可以排序的TreeSet存放，并重载Comparator的compare()

LogFiles(String path) {
        File logFile = new File(path);
        File[] temp = logFile.listFiles();
        files = new TreeSet<File>(new Comparator<File>() {
            @Override
            // 文件按日期排序 重写匿名内部类Comparator的compare()
            public int compare(File f0, File f1) {
                // TODO Auto-generated method stub
                String name0 = f0.getName();
                String name1 = f1.getName();
                // 按年份月份日期依次比较时间前后
                if (Integer.parseInt(name0.substring(0, 4)) < Integer.parseInt(name1.substring(0, 4))) {
                    return -1;
                }
                if (Integer.parseInt(name0.substring(0, 4)) > Integer.parseInt(name1.substring(0, 4))) {
                    return 1;
                }
                if (Integer.parseInt(name0.substring(5, 7)) < Integer.parseInt(name1.substring(5, 7))) {
                    return -1;
                }
                if (Integer.parseInt(name0.substring(5, 7)) > Integer.parseInt(name1.substring(5, 7))) {
                    return 1;
                }
                if (Integer.parseInt(name0.substring(8, 10)) < Integer.parseInt(name1.substring(8, 10))) {
                    return -1;
                }
                if (Integer.parseInt(name0.substring(8, 10)) > Integer.parseInt(name1.substring(8, 10))) {
                    return 1;
                }
                return 0;
            }

        });
        for (int i = 0; i < temp.length; ++i) {
            files.add(temp[i]);
        }

        lastDate = files.last().getName().substring(0, 10);
    }

4.LogFiles.outPutFile(String path, TypeArgument types, ProvinceArgument provinces):根据-type -province参数值过滤数据再输出

void outPutFile(String path, TypeArgument types, ProvinceArgument provinces) {
        try {
            // 打开out文件
            BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(path), "UTF-8"));
            String outline;
            // 处理type参数值 用boolean[]分别表示是否输出四种类型
            boolean[] typetemp = { false, false, false, false };
            if (types.value.equals("valuelist")) {
                for (String temp : types.valueList) {
                    switch (temp) {
                    case "ip":
                        typetemp[0] = true;
                        break;
                    case "sp":
                        typetemp[1] = true;
                        break;
                    case "cure":
                        typetemp[2] = true;
                        break;
                    case "dead":
                        typetemp[3] = true;
                        break;
                    default:
                        break;
                    }
                }
            }
            if (types.value.equals("")) {
                typetemp[0] = true;
                typetemp[1] = true;
                typetemp[2] = true;
                typetemp[3] = true;
            }
            // 若输出所有省份数据 遍历数据,并按省份拼音排序写入文件
            if (provinces.value.equals("")) {
                String[] provincesort = { "全国", "安徽", "北京", "重庆", "福建", "甘肃", "广东", "广西", "贵州", "海南", "河北", "河南", "黑龙江",

                    "云南", "浙江" };
                for (int i = 0; i < provincesort.length; ++i) {
                    String keytemp = provincesort[i];
                    int[] valuetemp = data.get(keytemp);
                    outline = keytemp;
                    if (typetemp[0]) {
                        outline = outline + " 感染患者" + valuetemp[0] + "人";
                    }

                    }
                    if (typetemp[3]) {
                        outline = outline + " 死亡" + valuetemp[3] + "人";
                    }
                    bw.write(outline);
                    bw.newLine();
                }
            }
            // 若只输出-province参数值省份数据
            if (provinces.value.equals("valuelist")) {
                for (String provincetemp : provinces.valueList) {
                    int[] valuetemp = data.get(provincetemp);
                    outline = provincetemp;
                    if (typetemp[0]) {

                    }
                    if (typetemp[2]) {
                        outline = outline + " 治愈" + valuetemp[2] + "人";
                    }

            bw.newLine();
            bw.flush();
            bw.close();
        } catch (Exception e) {

<h3 id="7">七、单元测试性能及优化</h3>
下面是上述单元测试的覆盖率表格，覆盖率达74.1%

<img src="https://img2018.cnblogs.com/blog/1934203/202002/1934203-20200220171453411-1041799833.png" width=800 />

可以非常明显地发现原单元测试的覆盖率短板在于对Statistic类的测试，再次展开

<img src="https://img2018.cnblogs.com/blog/1934203/202002/1934203-20200220171837705-187235220.png" width=700 />

定位到原单元测试遗漏的函数Statistic.outPutFile(String, TypeArgument, ProvinceArgument)
针对Statistic.outPutFile(String, TypeArgument, ProvinceArgument)编写单元测试

@Test
public void outPutFileOfStatisticTest() {
    Statistic aStatistic=new Statistic();
    
    //若-type是缺省的值,指定-province
    String path0="D:/outPutTest0.txt";
    TypeArgument aTypeArgument0=new TypeArgument("-type");
    String[] pro0= {"-province","福建"};
    ProvinceArgument aProvinceArgument0=new ProvinceArgument(pro0);
    aStatistic.outPutFile(path0, aTypeArgument0, aProvinceArgument0);

    //若-province是缺省的值，指定-type
    String path1="D:/outPutTest1.txt";
    String[] typ1= {"-type","ip","sp"};
    TypeArgument aTypeArgument1=new TypeArgument(typ1);
    ProvinceArgument aProvinceArgument1=new ProvinceArgument("-province");
    aStatistic.outPutFile(path1, aTypeArgument1, aProvinceArgument1);

    System.out.println("outPutFileOfStatisticTest OK");
    System.out.println("please check outPutTest.txt");
}

测试结果如下

经过改进后，覆盖率达到了90.5%

<h3 id="9">九、总结和收获</h3>
刚收到这份作业的时候，被五花八门的各种要求晃得眼花，拖延症发作，下意识地把它放放。奈何寒假真的太过清闲，放下没半天，又老实打开作业要求。第一个观感是这次疫情统计程序的作业与以往的作业很不一样，除了前置准备工作外，第一次收到一份较为完整的需求文档，按需求设计编程，并且不断使用commit记录签入。因此也是第一次完成一个程序的具体设计，再进行编程。
PS：作业周期很长，悠悠哉哉地写好幸福www
这次作业最大的收获应该是通过阅读邹欣老师的博客使用PSP表格来完成一项软件开发，过程中最出乎我意料的是，比起我预计的时间花费，设计的部分实际花费更多时间，而编码部分的时间比我预期的要少得多。过去编程时在编码花费大量时间，更多是因为编码前只有一个脑海中的模糊的体系，不完备不准确，时常推翻重写。
当然这次也存在这种情况：设计的不合理之处在编码时才发现。但都只是局部的修改，无伤大雅。比如在编码过程中发现设计的不合理之处，比如应用一个类来封装数据，而原来只在main中设计了一个map变量存放，因此再次修改了类图。又比如在初始设计时，由于对Java集合了解不够全面，选择用数组来存放目录下的日志文件，编码时涉及到文件排序的具体实现，就改为用TreeSet来存放。
