比较字典和txt文件的内容

Question

我正在尝试阅读诗篇txt文件（具有拼写错误）的内容，并将其与字典进行比较以过滤这些错误。我最终希望程序打印出包含拼写错误的txt文件的所有元素。我遇到了嵌套for循环的问题，因为我不确定如何遍历我的字典txt文件中的每个字符串并将其与我的诗txt文件进行比较。

public static String compareFileContents(String poem, String dictionary) 
throws FileNotFoundException, IOException{



  char[] buffer = null;
    try {
        BufferedReader br1 = new BufferedReader(new java.io.FileReader(poem));
        int bufferLength = (int)(new File(poem).length());
        buffer = new char[bufferLength];
        br1.read(buffer, 0, bufferLength);
        br1.close();
    } catch(IOException e) {
        System.out.println(e.toString());
    }



    String text = new String(buffer);
      String[] poem2 = text.split(" ");

  char[] buffer2 = null;
    try {
        BufferedReader br2 = new BufferedReader(new java.io.FileReader(dictionary));
        int bufferLength = (int)(new File(dictionary).length());
        buffer2 = new char[bufferLength];
        br2.read(buffer2, 0, bufferLength);
        br2.close();
    } catch(IOException e) {
        System.out.println(e.toString());
    }

   String dictionary2 = new String(buffer);
      String[] dictionary3 = dictionary2.split(" ");

      boolean found=false;

     for(int i=0;i<dictionary3.length;i++){
       for(int j=0;j<poem2.length;j++)  {
        if(!poem2[j].equals(dictionary3[i])) {
            System.out.println(poem2[j]);

        }
     }
     }

Answer 1

你有正确的想法，你只是颠倒你的嵌套循环。你想首先遍历诗中的每个单词。然后，对于诗的每个单词，循环遍历字典中的每个单词。如果找到匹配项，请继续。如果你在没有找到当前诗词的匹配的情况下遍历整个字典，你就会发现拼写错误。你可以像这样实现它。

您还会使用不正确的分隔符进行拆分。由于您的诗词由空格和换行符分隔，您应该使用正则表达式按空格分割。同样，由于你的字典单词被换行符分割，你应该按换行符分开。

// ...
String[] poem2 = text.split("\\s+");

// ...
String[] dictionary3 = dictionary2.split("\n");

for(int i = 0; i < poem2.length; i++) {
    boolean found = false;
    for(int j = 0; j < dictionary3.length; j++) {
        if(poem2[i].equals(dictionary3[j])) {
            found = true;
            break;
        }
    }
    if(!found) {
        System.out.println(poem2[i]);
    }
}

这是一个较晚的答案，它基于为检查TextArea中的拼写而编写的拼写检查器
可以下载字典HERE words_alpha.txt的作品
这是用JavaFX 8用Netbeans 8.2编写的
