java - 读取txt文件并用换行符显示数据

Question

这是我读取 txt 文件的代码，但我似乎无法正确安排文件内容的输出。

这是文件内容:

venti lador 13 male taguig

pito dingal 26 male pateros

dony martinez 24 male hagonoy

package testprojects;

import java.io.BufferedReader;
import java.io.FileReader;

public class ReadTextFile {
    public static void main(String args[]) throws Exception {
        BufferedReader bf = new BufferedReader(new FileReader("C://Users/PAO/Desktop/sampletxt.txt"));
        String line;

        while ((line = bf.readLine()) != null) {
            String[] value = line.split(" ");

            for (int x = 0; x < value.length; x++) {
                if (x >= 5) {
                    System.out.println();
                }
                System.out.print(value[x] + " ");
            }
        }
    }
}

输出:

venti lador 13 male taguig pito dingal 26 male pateros dony martinez 24 male hagonoy

期望的输出:

venti lador 13 male taguig

pito dingal 26 male pateros

dony martinez 24 male hagonoy

Answer 1

将您的条件更改为

if((x + 1) % 5 == 0 || (x == value.length - 1))

这样它就会在每 5 个数据处跳行，或者如果您到达行的最后一个数据。

你会得到这样的东西:

System.out.print(value[x] + " " );
if((x + 1) % 5 == 0 || (x == value.length - 1))
    System.out.println();
