原文地址：https://blog.csdn.net/qq_23974323/article/details/80003815

需求：實現逐行讀取txt文件，並寫入到實體類的list集合中去

代碼：

package Test;
 
import java.io.BufferedReader;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.List;
 
/**

public class readTxt {
	public static String paths="e:\\realdata\\0303658100.txt";
	public static List<TxtObject> readTxts() throws IOException {
		 InputStreamReader isr = new InputStreamReader(new FileInputStream(paths), "gbk");
         BufferedReader br = new BufferedReader(isr);
		String line = null;
		int count = 0;
		List<TxtObject> list = new ArrayList<TxtObject>();
		while ((line = br.readLine()) != null) {
			TxtObject txt = new TxtObject();
			String[] arr = line.split("\\|");
			if (arr.length > 5) {
				txt.setMerid(arr[0]);
				txt.setMername(arr[1]);
				txt.setAddress(arr[2]);
				txt.setName(arr[3]);
				txt.setTel(arr[4]);
				txt.setDate(arr[5]);
				list.add(txt);
			}
			count++;
		}
		System.out.println(list);
		System.out.println("讀取總條數：" + count + "||讀取的list的長度" + list.size());
		return list;
	}
 
	public static void main(String[] args) throws IOException {
		readTxts();
	}
	public static class TxtObject {
		private String merid;
		private String mername;
		private String address;
		private String name;
		private String tel;
		private String date;
		public String getMerid() {
			return merid;
		}
		public void setMerid(String merid) {
			this.merid = merid;
		}
		public String getMername() {
			return mername;
		}
		public void setMername(String mername) {
			this.mername = mername;
		}
		public String getAddress() {
			return address;
		}
		public void setAddress(String address) {
			this.address = address;
		}
		public String getName() {
			return name;
		}
		public void setName(String name) {
			this.name = name;
		}
		public String getTel() {
			return tel;
		}
		public void setTel(String tel) {
			this.tel = tel;
		}
		public String getDate() {
			return date;
		}
		public void setDate(String date) {
			this.date = date;
		}
		public TxtObject() {
			super();
		}
		@Override
		public String toString() {
			return "TxtObject [merid=" + merid + ", mername=" + mername + ", address="
					+ address + ", name=" + name + ", tel=" + tel + ", date=" + date
					+ "]";
		}
 
		}
 }

0303658100.txt文件內容如下：

100|100000|8|
1|12432789|0|6227001234896754569|4575.23|01|
2|12432789|0|6227001234896754569|4325.78|01|

運行結果：

[TxtObject [merid=1, mername=12432789, address=0, name=6227001234896754569, tel=4575.23, date=01], TxtObject [merid=2, mername=12432789, address=0, name=6227001234896754569, tel=4325.78, date=01]]
讀取總條數：3||讀取的list的長度2
