我已经完成了从一种方法返回列表的操作，并试图从另一种方法接收列表数据以将其写入excel文件，但是它仅打印最后一行。 请帮助我我缺少的部分。提前致谢。 1.方法一readingFile正在读取文本文件 2.第二种方法是从方法一接收到的列表数据中写入文件
我的两种方法的代码如下
package one;

import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import java.text.ParseException;

import java.util.Date;

SimpleDateFormat sdf = new SimpleDateFormat("hh:MM.ss");
SimpleDateFormat parsingSdf = new SimpleDateFormat("hh:MM.ss a");
Object[] received = new Object[3];
static ArrayList<Object[]> list= new ArrayList<Object[]>();
public ArrayList<Object[]> readingFile() throws IOException{
try{
File fi = new File(input_path);
File[] fileCount = fi.listFiles();
for(int i = 0;i<fileCount.length;i++){
File file = fileCount[i];
if(file.isFile()){
System.out.println("Total file count : "+fileCount.length);
String fileName = file.getName();
System.out.println("File name : "+fileName);
String data;
br = new BufferedReader(new FileReader(input_path+"\\"+fileName));
while((data = br.readLine())!=null){
if(data.contains(">")){
String dat = data.substring(data.indexOf(" ")+1,data.indexOf("-")-1);
//System.out.println(dat);
Date date = sdf.parse(dat.substring(dat.indexOf(" "),dat.lastIndexOf(".")));
//System.out.println(date);
String timeFormat = parsingSdf.format(date);
//System.out.println(timeFormat);
received[0] = dat.substring(dat.indexOf("0"),dat.indexOf(" ")+1)+timeFormat;
//System.out.println(received[0]);
received[1] = data.substring(data.indexOf("<")+1,data.indexOf(",")-1);
//System.out.println(received[1]);
received[2] = data.substring(data.indexOf("Target"),data.lastIndexOf("."));
//System.out.println(received[2]);
list.add(received);
}
}
}
}
}catch(FileNotFoundException | ParseException fe){
System.out.println(fe.getMessage());
}
return list;
}
