使用java獲取和設置來自文本文件的數據

Question

我有一個文本文件，其中包含4個不同的選項「開始時間」，「結束時間」，「ID」和「值」，每個選項卡均由製表符分隔。我需要獲得每一點信息，並將其設置爲等於我的類的構造函數中的參數。 Iv完成基本設置並獲取方法，但從未使用過文本文件中的數據。 Heres到目前爲止所獲得的結果。

import java.util.Date; 
import java.io.BufferedReader; 
import java.io.FileNotFoundException; 
import java.io.FileReader; 
import java.io.IOException; 

public class Sensor { 
//need all info for sensors such as sensor ID, Ontime, Offtime, Label 
    //needs to store all sensor data in memory 
    //try using jfreechart again instead of manually drawing 

    private Date startTime1; 
    private Date endTime1; 
    private String sensorID1; 
    private int sensorState1; 
    String fileName = "C:/kasterenDataset/kasterenSenseData.txt"; 

    public Sensor(Date startTime, Date endTime, String sensorID, int sensorState){ 
     startTime = startTime1; 
     endTime = endTime1; 
     sensorID = sensorID1; 
     sensorState = sensorState1; 


    } 

    public void setStartTime(){ 
     String line = null; 

      try { 
       // FileReader reads text files in the default encoding. 
       FileReader fileReader = new FileReader(fileName); 

       // Always wrap FileReader in BufferedReader. 
       BufferedReader bufferedReader = new BufferedReader(fileReader); 

       //start reading from the 24th line on the text file 
       int lineNumber = 0; 
       while((line=bufferedReader.readLine())!=null){ 
        lineNumber++; 
        if (lineNumber >= 24) { 
          String values[] = line.split("\\t", -1); 

        } 

       } 
       bufferedReader.close();   
      } 
      catch(FileNotFoundException ex) { 
       System.out.println(
        "Unable to open file '" + 
        fileName + "'");     
      } 

      catch(IOException ex1) { 
       System.out.println(
        "Error reading file '" 
        + fileName + "'");     
      }  
      } 
    public void getStartTime(){ 

    } 

    public void getEndTime(){ 


    } 

    public void getSensorID(){ 

    } 

    public void getSensorState(){ 

    } 

} 

這是一些數據從文本文件

Answer 1

不要做這樣的。 Getters和Setter只是一個不直接公開屬性的約定。創建一個方法來加載不是getter或setter的數據。
