Question

首先，让我作为序言：我正在编写一个程序，允许我拿三个文件，每个文件包含一段不同的圣经段落，并计算单词，行和字符的数量。我的一个问题是，文件的第一行仅包含特定翻译的版本（即KJV）。我想让它开始运行，同时跳过文件的第一行。

到目前为止，我的代码是：

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

 public class Assign6
 {
  public static void main(String[]args) throws Exception{

        int wordCount = 0;
        int lineCount = 0;
        int charCount = 0;
        java.io.File file1 = new java.io.File("translation1.txt");
        java.io.File file2 = new java.io.File("translation2.txt");
        java.io.File file3 = new java.io.File("translation3.txt");
        java.io.PrintWriter file4 = new java.io.PrintWriter("CompareInfo.txt");
        Scanner input = new Scanner(file1);
        Scanner input2 = new Scanner(file2);
        Scanner input3 = new Scanner(file3);


        while(input.hasNextLine()){

                 String line = input.nextLine();

                 lineCount++;

                 String str[] = line.split((" "));
                       for(int i = 0; i <str.length; i++){
                          wordCount++;
                         }
                      charCount += (line.length()); 

                }
                file4.println("In the King James, there are " + lineCount + " Lines, " + wordCount + " Words, and " + charCount + " Characters."); 
                lineCount = 0;
                charCount = 0;
                wordCount = 0;

                while(input2.hasNextLine()){

                 String line = input2.nextLine();

                 lineCount++;

                 String str[] = line.split((" "));
                       for(int i = 0; i <str.length; i++){
                          wordCount++;
                         }
                      charCount += (line.length()); 

                }
                 file4.println("In the NIV, there are " + lineCount + " Lines, " + wordCount + " Words, and " + charCount + " Characters.");

                 lineCount = 0;
                 wordCount = 0;
                 charCount = 0;

                 while(input3.hasNextLine()){

                 String line = input3.nextLine();

                 lineCount++;

                 String str[] = line.split((" "));
                       for(int i = 0; i <str.length; i++){
                          wordCount++;
                         }
                      charCount += (line.length()); 

                }
                file4.println("In the Message, there are " + lineCount + " Lines, " + wordCount + " Words, and " + charCount + " Characters.");

    file4.close();
    System.out.println("File written.");     
  }
}

如果它只是文本文件的第一行，那么你认为if语句只会增加一次吗？如果是这样的话，我究竟会怎么做呢？

Answer 1

在循环通过其他行之前读取一行？喜欢：

Scanner input = new Scanner(file1);
Scanner input2 = new Scanner(file2);
Scanner input3 = new Scanner(file3);

input.nextLine();
input2.nextLine();
input3.nextLine();

while(input.hasNextLine()){
//etc

所以它只是跳过它们，因为读者已经读了一次。

只需从第二行读取下来
