如何阅读这个JSON(How to read this JSON)

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class ReadFile {
  public static void main(String[]args) throws IOException{

      FileReader in = new FileReader("C:/test.txt");
      BufferedReader br = new BufferedReader(in);
      String line = "";
      String wholeReportText="";
      while ((line = br.readLine()) != null) {
         wholeReportText += line;
      }
      in.close();

           Pattern pattern = Pattern.compile("Movies(.*?)");
           Matcher matcher = pattern.matcher(wholeReportText);
           // check all occurance
           while (matcher.find()) {
                   System.out.println(matcher.group(1));
           }

      Pattern daypat = Pattern.compile("Tuesday (.*?)");
      Matcher daymat = daypat.matcher(wholeReportText);
      // check all occurance
      while (daymat.find()) {
            System.out.println(matcher.group(1));
      }


  }
}
 
 在算法的情况下，您的问题需要在子问题中打破 
 
 
 
 步骤1）列出需要解析的所有文件（java NIO中的java FileFilter中的文件API和java7中的Paths API） 
 
 
 步骤2）逐个读取文件并从中提取数据（上面的示例代码） 
 
 
 步骤3）将提取的数据存储在一些HashMap或ArrayList中 
 
 
 步骤4）根据您的要求使用集合 
 

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class ReadFile {
  public static void main(String[]args) throws IOException{

      FileReader in = new FileReader("C:/test.txt");
      BufferedReader br = new BufferedReader(in);
      String line = "";
      String wholeReportText="";
      while ((line = br.readLine()) != null) {
         wholeReportText += line;
      }
      in.close();

           Pattern pattern = Pattern.compile("Movies(.*?)");
           Matcher matcher = pattern.matcher(wholeReportText);
           // check all occurance
           while (matcher.find()) {
                   System.out.println(matcher.group(1));
           }

      Pattern daypat = Pattern.compile("Tuesday (.*?)");
      Matcher daymat = daypat.matcher(wholeReportText);
      // check all occurance
      while (daymat.find()) {
            System.out.println(matcher.group(1));
      }


  }
}
 
Your Problem needs to be broke in sub problems as in case of algorithms 
 
 
 
Step 1) To list all the files which you need to parse (File API in java FileFilter in java NIO and Paths API in java7)
 
 
Step 2) Read and extract data from file one by one (sample code above)
 
 
Step 3) Store the extracted data in some HashMap or ArrayList 
 
 
Step 4) Use collections as per your requirement
