java - 如何查找列表中每个单词的字符数？ ( java )

Question

我想要输出说

每个单词的总字母数为:

艾玛=4

泰勒 = 6

雅各布 = 5

罗杰=5

日本 = 2

我知道我的 for 循环是错误的，它输出所有名称的总字符数。

Blockquote

public static void main(String[] args){

List<String> myList = Arrays.asList("Emma", "Taylor", "Jacob", "Roger", "JP");// list of names

String[] arrayOfNames = new String[myList.size()]; 

myList.toArray(arrayOfNames);


    System.out.println("List of names: " +
    Arrays.toString(arrayOfNames));

    String myL = myList.toString();

    String[] words = myL.split(" ");

    int total = 0;

    for (int i = 0; i < words.length; i++) //for loop incorrect

      {

        total += words[i].length();
      }

         System.out.println("Total letters per word is: "+total);//see above

       }
}

你把事情搞得太复杂了，需要尝试这样的事情:

public static void main (String[] args) throws java.lang.Exception
{
    List<String> myList = Arrays.asList("Emma", "Taylor", "Jacob", "Roger", "JP");
    System.out.println("Total letters per word is: ");
    for (int i = 0; i < myList.size(); i++) //for loop incorrect
    {
    System.out.println(myList.get(i)+" = " + myList.get(i).length());
    }
}
