在java中同时写入2个文件

Question

我想用相同的数据同时写入2个不同的txt文件，但目前我可以覆盖一个文件，但另一个，帮助人们？

            if (choice.charAt(0) == 'y' || choice.charAt(0) == 'Y'){
                credits = 10;
                System.out.println("Redeemed! Congratulations! $1.00 worth of credits have been added to your account.");
                int finalpoints = points - credits;
                try {
                    FileWriter fw = new FileWriter("Transaction.history",true);
                    fw.write(firstname + ";" + Integer.toString(finalpoints) + ";" + "$1.00" + ";" + dateToPrintToFile + "\r\n");
                    fw.close();

                }catch (IOException ee){
                    System.out.println("Input file not found!");
                }
                //int finalpoints1 = points - credits;
                try {
                    FileWriter fw = new FileWriter("Points" , true);
                    fw.write(firstname + ";" + Integer.toString(point -credits));
                    fw.close();
                }catch (IOException ee){
                    System.out.println("Input file not found!");
                }

            }
