java检查字符串中的单词是否在数组中

Question

我正在制作一个聊天机器人，我想让它检查您键入的任何单词是否与预定义列表中的单词匹配

例如：我键入I'm good thanks!
我有一个带有awesome、perfect、happy和good的列表
我希望程序检查I'm、good或thanks!是否在列表中

        System.out.println("I don't really understand that...");
    }


}

} 这就是我所尝试的goodadj是我要搜索的列表，good是该列表中的输入词。 我被允许使用任何我想要的，这个项目只是为了好玩。感谢所有帮助我的人

Answer 1

/** Will return a set of words which are in the array and the sentence. */
public Set<String> checkWords( String sentence, String[] words )
{
  Set<String> result = new HashSet<>()
  String[] wordsInSentence = sentence.split(" ");
  for( String word : wordsInSentence )
  {
    for( String word2 : words )
    {
      if ( word.equals(word2) )
      {
        result.add( word );
        break;
      }
    }
  }
}

不过，如果使用集合而不是数组，效果会更好。它能更好地表达意思，使用哈希集会更有效

/** Will return a set of words which are in the set and the sentence. */
public Set<String> checkWords( String sentence, Set<String> words )
{
  Set<String> result = new HashSet<>()
  String[] wordsInSentence = sentence.split(" ");
  for( String word : wordsInSentence )
  {
    if ( words.contains(word) )
      result.add( word );
  }
}

Answer 2

您应该用空格“，”和“，”等分隔符分隔输入。。。数组中的所有单词都应该移动到一个集合中（最好是HashSet），并与

if (wordSet.contains(wordToCheck)) { doSomething(); }

您可以将所有输入单词和集合中的单词转换为小写或大写，以匹配“good”、“good”、“good”

Answer 3

使用将输入值存储到数组中。拆分（“”）

String [] baseValues = {"Awesome", "Perfect", "Happy", "Good"};

Scanner scan = new Scanner();

String userInput = scan.nextLine();

String [] inputArray = userInput.split(" ");

这给了你类似的东西[“我，m”，“很好”，“谢谢！”]

对于inputArray的每个值，循环这些值并将其与每个基值进行比较

或

获取输入的用户的输入，循环遍历数组中的值，查看它们提供给您的字符串是否正确。包含它们中的任何一个

**免责声明，这些是低效的，使用哈希集将是最佳方式，这些响应特定于数组
