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;
}
我在每列之间需要“一个制表符空间”(写入文本文件时)。喜欢
manu 25 data1
manc 35 data3
在我的代码中,我使用 bw.write("")
在每列之间创建空间。如何在那个地方使用“一个标签空间”而不是给“空间”。
最佳答案
您可以使用 \t
在文件中创建选项卡。
