从文件中读取文本并将每一行中的每个单词存储到单独的变量中 [英] Reading text from file and storing each word from every line into separate variables

问题描述

我有一个.txt文件，其内容如下:

I have a .txt file with the following content:

1 1111 47
2 2222 92
3 3333 81

我想逐行阅读并将每个单词存储到不同的变量中.

I would like to read line-by-line and store each word into different variables.

例如:当我读第一行"1 1111 47"时，我想将第一个单词"1"存储到var_1中，将"1111"存储到var_2中，将"47"存储到var_3中.然后，当转到下一行时，这些值应分别存储到相同的var_1，var_2和var_3变量中.

For example: When I read the first line "1 1111 47", I would like store the first word "1" into var_1, "1111" into var_2, and "47" into var_3. Then, when it goes to the next line, the values should be stored into the same var_1, var_2 and var_3 variables respectively.

我的初始方法如下:

import java.io.*;
class ReadFromFile
{
    public static void main(String[] args) throws IOException
    {
        int i;
        FileInputStream fin;
        try
        {
            fin = new FileInputStream(args[0]);
        }
        catch(FileNotFoundException fex)
        {
            System.out.println("File not found");
            return;
        }
        do 
        {
            i = fin.read();
            if(i != -1) 
                System.out.print((char) i);
        } while(i != -1);

        fin.close();
    }
}

请给我您的建议.谢谢

推荐答案

public static void main(String[] args) throws IOException {
    File file = new File("/path/to/InputFile");
    BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(file)));
    String line = null;
    while( (line = br.readLine())!= null ){
        // \\s+ means any number of whitespaces between tokens
        String [] tokens = line.split("\\s+");
        String var_1 = tokens[0];
        String var_2 = tokens[1];
        String var_3 = tokens[2];
    }
}
