java - 程序打印元音最多的单词

Question

我无法弄清楚这段代码有什么问题。无论我提供什么作为输入，代码都会打印 i 作为输出。如有任何帮助，我们将不胜感激。

public class VowelClass{

public static void main(String args[]){

String input;
System.out.println("Please enter your sentence: ");

Scanner scan = new Scanner(System.in);
input = scan.nextLine();

int maxVCount = 0;
String mostVowels = null;
String[] words = input.split("");

for (String word : words) {

  int vCount = 0;
  word = word.toLowerCase();

  for (int i=0; i<word.length(); i++){
    char x = word.charAt(i);
    if (x == 'a' || x == 'e' || x == 'i' || x == 'o' || x == 'u'){
    vCount++;
    }
  }
   if (vCount > maxVCount) {
    maxVCount = vCount;
    mostVowels = word;
   }
  }
    System.out.println("Word with most vowels is:");
    System.out.println(mostVowels);
  }
}

Answer 1

input.split(""); => input.split("");

您需要在单词之间进行拆分，因此请在拆分方法中使用“空格”字符。
