用java生成空的txt文件

名称要求为AS011_20210801-99.txt

20210801为递增值，其余为不变值。

做连续的一百个文件。

代码越简单越好，用batch文件写出来也可。

import java.io.BufferedWriter;
import java.io.FileWriter;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;

public class Main {

    public static void main(String[] args) throws Exception  {
        SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd");
        Date date = sdf.parse("20210801");
        Calendar c = Calendar.getInstance();
        c.setTime(date);
        
        for (int i = 0; i < 100; i++) {
            String time = sdf.format(c.getTime());
            try (BufferedWriter bw = new BufferedWriter(new FileWriter("AS011_"+time+"-99.txt"))) {
                    
            }
            
            c.add(Calendar.DATE, 1);
        }
    }
}

创建文件夹，将文件后缀格式改为bat，将以下代码复制到文件内，保存之后，双击运行即可。

@echo off
for /l %%i in (20210801,1,20210901) do echo=>AS011_%%i-99.txt
pause

如果有帮助到你，希望能够采纳支持一下，谢谢！

public class Test {
    public static void main(String[] args) {
        for (int i = 1; i<= 100; i++)
        {
            String fileName = "AS011_20210";
            fileName = fileName + String.valueOf(800 + i) + "-99.txt";
            File testFile = new File("D:" + File.separator + fileName);
            try {
                testFile.createNewFile();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    }
}

望采纳，谢谢

@echo off
set "year=%date:~0,4%"
set "month=%date:~5,2%"
set "day=%date:~8,2%"
set "hour_ten=%time:~0,1%"
set "hour_one=%time:~1,1%"
set "minute=%time:~3,2%"
set "second=%time:~6,2%"

if "%hour_ten%" == " " (
    type nul > %year%%month%%day%0%hour_one%%minute%%second%.txt
) else (
    type nul > %year%%month%%day%%hour_ten%%hour_one%%minute%%second%.txt
