我想知道如何添加文本和打印行以使格式类似于:https://i.gyazo.com/def6e157e24dc0ed0fe68e1509152405.png

   try
    {
        FileWriter writer = new FileWriter("Gamer Report Data.txt");
        writer.write(gamerName);
        writer.write(System.getProperty( "line.separator"));
        writer.write(gamerReport);
        writer.close();
    } catch (IOException e)
    {
        System.err.println("File does not exist!");
    }

    }

像这样:

 try
    {
        PrintWriter writer = new PrintWriter("Gamer Report Data.txt");
        writer.println("Player: " + gamerName);
        writer.println();
        writer.println("-------------------------------");
        //This line will split the gameReport string by the ':' separator
        //Into an array of strings.
        string[] report = gameReport.split(":");
        //Edit here with regards to latest comment
        //This will print the game score if the reports array has data.
        if(report == null) {
            writer.println("Game report was null.");
        } else if(report.length == 3) {
            writer.println("Game:" + report[0]+", score=" + report[1] +", minutes played="+ report[2]);
        }
        writer.close();
    } catch (IOException e)
    {
        System.err.println("File does not exist!");
    }

    }
