需求：实现逐行读取txt文件，并写入到实体类的list集合中去

代码：

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;
     
    /**
     * 逐行读取txt文件并写入到list实体类中
     * @author jun sun
     *
     */
    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("读取总条数：" + count + "||读取的list的长度" + 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文件内容如下：

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

运行结果：

[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]]
    读取总条数：3||读取的list的长度2
