我有一個當前運行在我編寫的Delphi應用程序中的進程,我需要將其轉換爲將在我們的Web應用程序上運行的Java進程。基本上我們的州財政(遺產)系統需要這個文件在一個特定的輸出。在德爾福它是這樣的:使用Java創建固定長度的平面文件
procedure CreateSHAREJournalFile(AppDate : string; ClassCode : string; BudgetRef : String; AccountNumber : string; FYEStep : integer);
var
GLFileInfo : TStrings;
MPayFormat, HPayFormat, TPayFormat : string;
const
//this is the fixed length format for each item in the file
HeaderFormat = '%-1s%-5s%-10s%-8s%-12s%-10s%-21s%-3s%-71s%-3s%-20s%-1s';
DetailFormat = '%-1s%-5s%-9s%-10s%-10s%-10s%-10s%-8s%-6s%-5s%-5s%-5s%-8s%-25s%-10s%-60s%-28s%-66s%-28s';
begin
try
//get the data from the query
with dmJMS.qryShare do
begin
SQL.Clear;
SQL.Add('SELECT SUM(TOTHRPAY) As HourPay, SUM(TOTMLPAY) As MilePay, SUM(TOTALPAY) AS TotalPay FROM JMPCHECK INNER JOIN JMPMAIN ON JMPCHECK.JURNUM = JMPMAIN.JURNUM WHERE PANELID LIKE ''' + Copy(AppDate, 3, 6) + '%'' ');
if FYEStep > -1 then
SQL.Add('AND WARRANTNO = ' + QUotedStr(IntToStr(FYEStep)));
Active := True;
//assign totals to variables so they can be padded with leading zeros
MPayFormat := FieldByName('MilePay').AsString;
while length(MPayFormat) < 28 do <br>MPayFormat := '0' + MPayFormat;
HPayFormat := FieldByName('HourPay').AsString;
while length(HPayFormat) < 28 do <br>HPayFormat := '0' + HPayFormat;
TPayFormat := Format('%f' ,[(FieldByName('TotalPay').AsCurrency)]);
while length(TPayFormat) < 27 do
TPayFormat := '0' + TPayFormat;
TPayFormat := '-' + TPayFormat;
//create a TStringlist to put each line item into
GLFileInfo := TStringList.Create;
//add header info using HeaderFormat defined above
GLFileInfo.Add(Format(HeaderFormat, ['H', '21801', 'NEXT', FormatDateTime('MMDDYYYY', Today), '', 'ACTUALS', '', 'EXT', '', 'EXT', '', 'N']));
//add detail info using DetailFormat defined above
GLFileInfo.Add(Format(DetailFormat, ['L', '21801', '1', 'ACTUALS', AccountNumber, '', '1414000000', '111500', '', '01200', ClassCode, '', BudgetRef, '', AccountNumber + '0300', '', MPayFormat, '', MPayFormat]));
GLFileInfo.Add(Format(DetailFormat, ['L', '21801', '2', 'ACTUALS', AccountNumber, '', '1414000000', '111500', '', '01200', ClassCode, '', BudgetRef, '', AccountNumber + '0100', '', HPayFormat, '', HPayFormat]));
GLFileInfo.Add(Format(DetailFormat, ['L', '21801', '3', 'ACTUALS', '101900', '', '1414000000', '111500', '', '01200', ClassCode, '', BudgetRef, '', '', '', TPayFormat, '', TPayFormat]));
//save TStringList to text file
GLFileINfo.SaveToFile(ExtractFilePath(Application.ExeName) + 'FileTransfer\GL_' + formatdateTime('mmddyy', Today) + SequenceID + '24400' + '.txt');
end;
finally
GLFileINfo.Free;
end;
end;
是否有格式選項Java中的等效項?或者保存到文本文件的TStringList?
感謝您的任何信息....沒有做過很多Java編程!

我發現這個鏈接,但沒有看到你如何格式化輸出: http://www.rgagnon.com/javadetails/java-0461.html – Leslie 2010-03-08 17:29:50
爲了將來的參考,這不是你如何編碼在Stackoverflow的代碼塊。只需將所有代碼縮進4個空格。 – Pointy 2010-03-08 17:30:20
感謝您的信息!我嘗試了各種各樣的東西,讓它看起來很正確!感謝編輯! – Leslie 2010-03-08 17:44:13
