有没有办法让我的拼写检查器正常工作

Question

问题是我正在尝试制作的拼写检查器。我有一个字典文件，其中包含大量要与用户输入进行比较的单词，因此它可以检测任何可能的拼写错误。我的问题是，无论您键入什么，它总是会说拼写不正确，而实际上拼写不正确。是否有任何解决方案或更好的方法来检测用户输入的销售错误。

import java.util.Scanner;

import java.io.File;

import java.io.FileNotFoundException;

public class SpellChecker2 {

public static void main(String[] args) throws FileNotFoundException

{

    Scanner input = new Scanner(System.in);

    System.out.println("Please enter a String"); 

    String userWord = input.nextLine();

    final String theDictionary = "dictionary.txt";

    String[] words = dictionary(theDictionary);

    boolean correctSpelling = checking(words, userWord);

if (!correctSpelling)

    {

    System.out.println("Incorrect spelling");

    }

else 

    {

    System.out.println("The spelling is correct");

    }

}

public static String[] dictionary(String filename) throws FileNotFoundException

{

    final String fileName = "dictionary.txt";

    Scanner dictionary = new Scanner(new File(fileName));

    int dictionaryLength =0;

    while (dictionary.hasNext())

    {

        ++dictionaryLength;

        dictionary.nextLine();

    }

    String [] theWords = new String[dictionaryLength];

        for ( int x = 0; x < theWords.length ; x++)

        dictionary.close();

    return theWords;

}

public static boolean checking(String[] dictionary, String userWord)

{

boolean correctSpelling = false;

    for ( int i =0; i < dictionary.length; i++)

    {

        if (userWord.equals(dictionary[i]))

        {

            correctSpelling = true;

        }

        else 

            correctSpelling = false;

    }

    return correctSpelling;

}

}

我得到的结果是：

           Please enter a String

           hello

           Incorrect spelling

正如你所看到的，即使我的拼写是正确的，它也会给出一个拼写不正确的错误。任何帮助都会很棒，并提前感谢您。

是的。从checking上返回true。正如您现在所拥有的那样，只有最后一个单词匹配时，它才能为真。喜欢，public static boolean checking(String[] dictionary, String userWord) {&nbsp; &nbsp; for ( int i =0; i < dictionary.length; i++) {&nbsp; &nbsp; &nbsp; &nbsp; if (userWord.equals(dictionary[i])) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return true;&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; }&nbsp; &nbsp; return false;}此外，您需要dictionary通过向数组中添加单词来填充您的内容。而且，我更喜欢try-with-resources显式close()调用。就像是，public static String[] dictionary(String filename) throws FileNotFoundException {&nbsp; &nbsp; final String fileName = "dictionary.txt";&nbsp; &nbsp; int dictionaryLength = 0, i = 0;&nbsp; &nbsp; try (Scanner dictionary = new Scanner(new File(fileName))) {&nbsp; &nbsp; &nbsp; &nbsp; while (dictionary.hasNextLine()) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ++dictionaryLength;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; dictionary.nextLine();&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; }&nbsp; &nbsp; String[] theWords = new String[dictionaryLength];&nbsp; &nbsp; try (Scanner dictionary = new Scanner(new File(fileName))) {&nbsp; &nbsp; &nbsp; &nbsp; while (dictionary.hasNextLine()) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; theWords[i] = dictionary.nextLine();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; i++;&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; }&nbsp; &nbsp; return theWords;}
