文字列をutilに変換する日付変換

Question

私は弊社の出席管理システムを作成しており、すべての従業員の出席は指紋バイオメトリックマシンによって生成されたテキストファイル上にあります。問題は、文字列の日付の配列をテキストファイルから変換してデータベースに保存しようとしていますが、それは "unparseable date error"を出してしまうことです。参照用のコードを参照してください。

public void getReadTextFile(String path) throws ParseException{ 
    sql = new String("INSERT INTO logs(EmpID, ValidDate, ValidTime,Processed, PRDate) VALUES(?,?,?,?,?)"); 
    BufferedReader br = null; 
    String[] ID = new String[3000]; 
    java.sql.Date[] vDate = new java.sql.Date[3000]; 
    Time[] vTime = new Time[3000]; 
    Date date = new Date(); 
    DateFormat format = new SimpleDateFormat("yyyy-MM-dd"); 
    try{ 
     FileInputStream fsStream = new FileInputStream(path); 
     br = new BufferedReader(new InputStreamReader(fsStream)); 
     String strLine; 
     br.readLine(); 
     int i = 0; 
     while((strLine = br.readLine()) != null){ 
      String[] arr = strLine.split("\\s+"); 
      java.util.Date qDate = format.parse(arr[5]); 
      ID[i] = arr[2]; 
      vDate[i] = new java.sql.Date(qDate.getTime()); 
      vTime[i] = java.sql.Time.valueOf(arr[6]); 
      java.sql.Date sqldate = new java.sql.Date(date.getTime()); 

      pstmt = data.prepareStatement(sql); 
      pstmt.setString(1, arr[2]); 
      pstmt.setDate(2, vDate[i]); 
      pstmt.setTime(3, vTime[i]); 
      pstmt.setInt(4, 1); 
      pstmt.setDate(5, sqldate); 
     } 
     i++; 

    }catch(IOException ex){ 
     System.out.println(ex.getMessage()); 
    }catch(SQLException ev){ 
     //System.out.println(ev.getMessage()); 
     ev.printStackTrace(); 
    }catch(ParseException pe){ 
     pe.printStackTrace(); 
    } 
    finally{ 
     try{ 
      if(br != null){ 
       br.close(); 
      } 
     }catch(IOException e){ 
      System.out.println(e.getMessage()); 
     } 
    } 
} 

これはスタックトレースです：

Answer 1

あなたは"yyyy-mm-dd"

DateFormat format = new SimpleDateFormat("yyyy-MM-dd"); 

の代わりに "yyyy-MM-dd"を使用し、 "2017年4月25日" のような日付を指定している場合

ここで、

M- Month in year. Number of M's determine length of format (e.g. MM, MMM or MMMMM) 
m- Minute in hour, 0-59 (normally mm) 

あなたは「2017年4月25日」のような日付を指定している場合は、代わりにスタックトレースがある"yyyy-mm-dd"

DateFormat format = new SimpleDateFormat("yyyy/MM/dd");
