java - 查找单个字符串中每个单词的平均字符数

Question

我有点卡在这个问题上了。我试图在一个字符串中存储 1 个或多个单词，找到所有单词的组合长度，然后将其除以单词数以找到平均值。我需要在 while 循环中执行此操作(这是作业的目标)

当我输入“Hello my name is”时，它返回长度为

Result:  
5  
2  
4  
2  

但我想要的是将这些结果相加然后除以字数

5+2+4+2 = 13  
13/4 = 3.25

这是我目前所拥有的:

Scanner in = new Scanner(System.in);

int counter = 0;
double sum = 0;

while (in.hasNext()) {
    String word = in.next();
    double totalchar = word.length();
    sum = totalchar + sum;
    counter++;


    double average = 0;
    if (counter > 0) {
        average = sum / counter;

    }
    System.out.println(average);
}

Answer 1

只需将average 计算和打印移到while 循环之外:

while (in.hasNext()) {
    String word = in.next();
    if (word.equals("exit")) {
        break;
    }
    double totalchar = word.length();
    sum = totalchar + sum;
    counter++;
}
double average = 0;
if (counter > 0) {
    average = sum / counter;
}
System.out.println(average);
