一个用JAVA解析TXT格式文本文档的程序举例

实体类

package txt;
public class AliDataRecord {

    private String FSTR_SCATSID;

    private String FSTR_DATE;

                    }
                    public void setFSTR_SCATSID(String fSTR_SCATSID) {

                    }
                    public String getFSTR_DESC() {
                        return FSTR_DESC;

                    public void setFSTR_DATE(String fSTR_DATE) {
                        FSTR_DATE = fSTR_DATE;
                    }

如何修改编码格式

解析类

package txt;

import java.io.*;
import java.util.ArrayList;
import java.util.List;

public class Txt {

    public static void readTxt(String filePath) {
        List records = new ArrayList();// 创建list
                                                                        // 将txt格式的数据存入数组

        try {
            File file = new File(filePath);
            if (file.isFile() && file.exists()) {
                InputStreamReader isr = new InputStreamReader(
                        new FileInputStream(file), "utf-8");
                BufferedReader br = new BufferedReader(isr);
                String lineTxt = null; // 读取文件的方法

                while ((lineTxt = br.readLine()) != null) {
                    String[] arrStrings = lineTxt.split(","); // 用于把一个字符串分割成字符串数组
                    AliDataRecord record = new AliDataRecord();
                    record.setFSTR_SCATSID(arrStrings[0]);
                    record.setFSTR_DESC(arrStrings[1]);
                    record.setFSTR_DATE(arrStrings[2]);
                    record.setNUM_TIME(arrStrings[3]);
                    record.setMIN_TIME(arrStrings[4]);
                    record.setNUMOF_ALARMS(arrStrings[5]);
                    record.setUTIM(arrStrings[6]);
                    records.add(record); // 用set方法将取值分别添加到对应字符串数组 ，用add方法存入list

                }
                br.close();
                for (int i = 0; i < records.size(); i++) {
                    System.out.println(records.get(i));
                }

            } else {
                System.out.println("文件不存在!");
            }
        } catch (Exception e) {
            System.out.println("文件读取错误!");
        }
    }

    public static void main(String[] args) {
        String filePath = "D:\\Work\\myeclipse\\B\\txt\\src\\aaaaa.txt"; // 读取文件的绝对路径
        readTxt(filePath);
    }

}

add方法和set方法的区别

add方法是在某个指定的位置加上某个对象,并将原来的位置的那个对象向后挤了一格。

set方法是将原来位置上的那个给取代了,并将原来位置上对象的返回。
