我有一個問題,在文件中寫入這些細節。 我想寫在文件中的這個細節,但一些如何這個功能創建文件在特定的位置,但它不寫入任何文件。如何在Java中使用BufferedWriter和FileWriter將詳細信息寫入文件?
public void writeBillToFile(double amount , double billingAmount,double taxAmount,
double discount ,double transactionID , double billingNumber ,
int customerID , String tableNumber ,ArrayList listObject )
{
FileWriter fw=null ;
BufferedWriter bw =null;
Date d=new Date();
long currentTimestamp=d.getTime();
try{
fw = new FileWriter("D:/study/ADVANCE_JAVA/PrOgRaMs/WEB_APPS/00_COS-THE MEGA PROJECT/COS_March_03/GeneratedBill/bill"+currentTimestamp+".txt" , true);
bw= new BufferedWriter(fw);
System.out.println("Date and Time :: "+d.toString() +"\t Bill No :: "+billingNumber+"\t Transaction ID :: "+transactionID+"\n");
bw.write("Date and Time :: "+d.toString() +" Bill No::"+billingNumber+" Transaction ID::"+transactionID);
bw.newLine();
Iterator iteratorObject= listObject.iterator();
while(iteratorObject.hasNext())
{
ItemInSessionModel itemObject = (ItemInSessionModel)iteratorObject.next();
bw.write(itemObject.getItemName()+" "+itemObject.getItemQty()+" "+itemObject.getItemRate()+" "+(itemObject.getItemRate()*itemObject.getItemQty()));
bw.newLine();
}
bw.write("Total Amount ::"+amount);
bw.newLine();
bw.write("Discount ::"+discount);
bw.newLine();
bw.write("TAX ::"+taxAmount);
bw.newLine();
bw.write("Bill Amount ::"+billingAmount);
bw.newLine();
bw.write("Thank You...!");
System.out.println("Successfully Writen in File...!");
}catch(Exception e)
{
System.out.println("Exception in FILE IO :: "+e);
}
finally
{
try{
fw.close();
bw.close();
}catch(Exception e){}
}
}
您能幫我編寫打印相同文件的代碼嗎? 我已經通過了Oracle的2DPrinting教程,但我想打印我生成的相同的txt文件。所以你能幫我解釋一下嗎? – CyberWorm 2012-03-06 20:48:18
