如何使用“标签空间”在文本文件中写 [英] how to use "tab space" while writing in text file

问题描述

 SimpleDateFormat formatter = new SimpleDateFormat("ddMMyyyy_HHmmSS");
 String strCurrDate = formatter.format(new java.util.Date());
 String strfileNm = "Cust_Advice_" + strCurrDate + ".txt";
 String strFileGenLoc = strFileLocation + "/" + strfileNm;
 String strQuery="select name, age, data from basetable";
 try {

     stmt = conn.createStatement();
     System.out.println("Query is -> " + strQuery);
     rs = stmt.executeQuery(strQuery);

     File f = new File(strFileGenLoc);
     OutputStream os = (OutputStream)new FileOutputStream(f);
     String encoding = "UTF8";
     OutputStreamWriter osw = new OutputStreamWriter(os, encoding);
     BufferedWriter bw = new BufferedWriter(osw);

     while (rs.next() ) {

         bw.write(rs.getString(1)==null? "":rs.getString(1));
         bw.write("  ");
         bw.write(rs.getString(2)==null? "":rs.getString(2));
         bw.write("  ");

     }
     bw.flush();
     bw.close();
 } catch (Exception e) {
     System.out.println(
         "Exception occured while getting resultset by the query");
     e.printStackTrace();
 } finally {
     try {
         if (conn != null) {
             System.out.println("Closing the connection" + conn);
             conn.close();
         }
     } catch (SQLException e) {
         System.out.println(
             "Exception occured while closing the connection");
         e.printStackTrace();
      }
    }
         return objArrayListValue;
  }

我需要在每列之间一个标签空间（同时写入文本文件）。喜欢

i need "one tab space" in between each column(while writing to text file). like

   manu 25 data1
   manc 35 data3

在我的代码中，我使用 bw.write（）在每列之间创建空格。如何在那个地方使用一个标签空间而不是给空间。

in my code i use bw.write(" ") for creating space between each column. how to use "one tab space" in that place instead of giving "space".

推荐答案

您可以使用 \t 创建一个标签页文件。

You can use \t to create a tab in a file.
