Java 为什么它读的是字母的数量而不是单词？

我必须写一个程序，从文本文件中读取输入

Beware the Jabberwock, my son, 
the jaws that bite, the claws that catch, 
Beware the JubJub bird and shun 
the frumious bandersnatch. 

我应该打印行数、最长行数、每行上的令牌数以及每行上最长令牌的长度

我试图弄明白为什么我的代码是读字母的数量而不是单词的数量

Line 1 has 5 tokens (longest = 11) 
Line 2 has 8 tokens (longest = 6) 
Line 3 has 6 tokens (longest = 6) 
Line 4 has 3 tokens (longest = 13) 
Longest line : the jaws that bite, the claws that catch,

这应该是我的输出

import java.io.*;
import java.util.*;

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

        Scanner console = new Scanner ( System.in);
        System.out.println(" ");
        System.out.println();
        System.out.println("Please enter  a name of a file " );
        String name = console.nextLine();
        Scanner input = new Scanner ( new File (name));
        while (input.hasNextLine()) {
            String line = input.nextLine();
            inputStats(new Scanner(line));
        }
    }//end of amin

    public static void inputStats (Scanner input)
            throws FileNotFoundException{
        int numLines=0;
        int numwords=0;
        int Longest=0;
        String maxLine = "";

        while (input.hasNextLine()){
            String next = input.nextLine();

            numwords += next.length();
            numLines++;
        }//end of while

        System.out.print("Line " + numLines + " has ");
        System.out.print(numwords + "tokens " );
        System.out.println("(longest = " + Longest + ")");
    }//end of method
}// end of class

将每行的长度添加到

numwords

计数器变量，而不是每行的字数。而不是

numwords += next.length();

可以根据空格进行拆分

numwords += nextLine.split("\\s+").length;

如果我明白你在找什么像这样的东西应该行得通

public static void inputStats(Scanner input)
      throws FileNotFoundException {
  int numLines = 0;
  int numwords = 0;
  String longest = "";
  String maxLine = "";

  while (input.hasNextLine()) {
    String nextLine = input.nextLine();
    nextLine = (nextLine != null) ? nextLine
        .trim() : "";
    if (nextLine.length() > maxLine.length()) {
      maxLine = nextLine;
    }
    StringTokenizer st = new StringTokenizer(
        nextLine);
    while (st.hasMoreTokens()) {
      String token = st.nextToken();
      token = (token != null) ? token.trim() : "";
      if (token.length() == 0) {
        continue;
      }
      numwords++;
      if (token.length() > longest.length()) {
        longest = token;
      }
    }
    numLines++;
  }// end of while
  System.out.print("Line " + numLines + " has ");
  System.out.print(numwords + "tokens ");
  System.out.println("(longest = " //
      + longest + ")");
}// end of method

如果我试着只数一个单词的字母而不是整行的话，我该如何改变这一点呢。。如果（next.length（）>maxLine.length（））{maxLine=next；这是给我的字母数，但在这行中不清楚你的意思。我建议发布另一个问题，用该代码解释什么不起作用：）
