文本文档中多个词语出现的次数

 

由于女友最近要交毕业论文，想要将自己整理的文档，查询其中的高频词汇，我就找了一段查词代码并进行修改，算是满足了基本要求！！！分享一下

源码

public static void main(String[] args) {
        String path = null;
        int j =1;
        String[] a = { "时间", "小时", "酒店", "景区", "游客", "公里", "景点", "地方", "分钟", "晚上", "选择", "开车", "出发", "到达", "租车", "公园",
                "停车场", "门票", "下午", "然后", "前往", "游览", "当地", "停车", "体验", "住宿", "游记", "附近", "高速", "吃饭" };
        for (;j < 61; j++) {
            path= "D:\\" + j + ".txt";
            System.out.println("\n");
            System.out.println("第"+j+"篇");
            for (int i = 0; i < a.length; i++) {
                serchKey(j,a[i],path);
            }
        }
    }

    private static void serchKey(int j,String key,String path) {
        BufferedReader br = null;
        try {
            br = new BufferedReader(new FileReader(path));
            StringBuffer sb = new StringBuffer();
            String str = null;
            while ((str = br.readLine()) != null) {
                sb.append(str);
            }

            String regex = key.trim();
            Pattern pattern = Pattern.compile(regex);
            Matcher matcher = pattern.matcher(sb);
            int num = 0;
            while (matcher.find()) {
                num++;
            }

            
            System.out.println(regex + ":" + num);

        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } finally {
            try {
                if (null != br) {
                    // 关闭资源
                    br.close();
                }
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    }

比对才是核心！！！
