篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了为什么问这个单词出现多少次，为什么我总是得到138相关的知识，希望对你有一定的参考价值。

我试图找出一个状态在一列csv文件中出现多少次。它也只打印一半的状态。我的代码如下

import java.io.BufferedReader;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.FileReader;
import java.util.ArrayList;
import java.util.List;
import java.util.Arrays;

public class csvtxt {

   public static void main(String a[]){
      StringBuilder sb = new StringBuilder();
      String strLine = "";
      List<String> list = new ArrayList<String>();
      try {
         BufferedReader br = new BufferedReader(new FileReader("C:\\Users\\dbb38\\Downloads\\customers_export_111 - customers_export_1 (1).csv"));
         while (strLine != null)
         {
            strLine = br.readLine();
            sb.append(strLine);
            sb.append(System.lineSeparator());
            strLine = br.readLine();
            if (strLine==null)
               break;
            list.add(strLine);
         }
         //
         String wordToSearchFor = "Alabama";
         int Alabama = 0;
         for(String Alabama1 : list)
         {
            if(Alabama1.equals(wordToSearchFor)) 
            {
               Alabama++;
            }
         }
         System.out.println("Alabama = " + "["+ Alabama +"]");
         //
         String wordToSearchFor1 = "Alaska";
         int Alaska = 0;
         for(String Alaska1 : list)
         {
            if(Alaska1.equals(wordToSearchFor)) 
            {
               Alaska++;
            }
         }
         System.out.println("Alaska = " + "["+ Alaska +"]");
         //
         String wordToSearchFor2 = "Arizona";
         int Arizona = 0;
         for(String Arizona1 : list)
         {
            if(Arizona1.equals(wordToSearchFor)) 
            {
               Arizona++;
            }
         }
         System.out.println("Arizona = " + "["+ Arizona +"]");
         //
         System.out.println(Arrays.toString(list.toArray()));
         br.close();
      } catch (FileNotFoundException e) {
         System.err.println("File not found");
      } catch (IOException e) {
         System.err.println("Unable to read the file.");
      }
   }
}

这里是我得到的输出。我切断了一些输出，因为95881的字符太多。

Alabama = [138]
Alaska = [138]
Arizona = [138]

应该有35个佛蒙特州的，但只打印其中的17个。任何帮助，将不胜感激！]

答案

替换

if(Arizona1.equals(wordToSearchFor))

with

if(Arizona1.equals(wordToSearchFor2))

您也需要对其他人进行类似的更改。看到你的错误了吗？
