Question

我在total played创建一个程序，该程序读取文本文件并显示各种输出，例如total won和total played。

三个输出中的两个我必须完美地显示total won和return players，但我无法使最后一个工作，total played需要total won和List<Double> RP = data.RegexCheck(fileData.toString(), "(Return Players: £) (totalPlayed/totalWon)*100",2); //ReturnPlayers double ReturnPlayers = 0; for(double d : RP){ ReturnPlayers+= d; }来生成输出。

我拥有的是：

return players

我得到(totalPlayed/totalWon)*100为try(BufferedReader br = new BufferedReader(new FileReader("myFile.txt"))){}的事实。我该怎么做呢？

修改

我读取文本文件的方式是

System.out.println("The total times played is: " + totalPlayed);
System.out.println("The total times won is: " + totalWon);
System.out.println("Return Players value is: " + ReturnPlayers);

输出的编写方式是

RP

编辑＃2

它正常工作，但最终输出0.0不显示任何内容，只显示1240，我觉得它应该显示一个数字，因为它在两个输出中显示分别显示数字320和387.5，然后再乘以100，这样可以显示myFile.txt

Start Game Game number: 1 Player: lose End Game Start Game Game number: 2 Player: lose End Game Start Game Game number: 3 Player: lose End Game Start Game Game number: 4 Player: won End Game Start Game Game number: 5 Player: won End Game Start Game Game number: 6 Player: lose End Game Start Game Game number: 7 Player: won End Game Start Game Game number: 8 Player: won End Game的一个例子是

var query = from r in Ctx.Reg
            select new
            {
                IdReg = r.Id,
                ...
                Status1 = r.Hist.OrderByDescending(o => o.Id).Take(1).Any(x=> x.Status == 2),
                Status2 = r.Hist.OrderByDescending(o => o.Id).Skip(1).Take(1).Any(x=> x.Status == 5)
            };

Java代码

try(BufferedReader br = new BufferedReader(new FileReader("myFile.txt"))){
    String line = null;
    int wonCounter = 0;
    int lostCounter = 0;

    while((line=br.readLine()) != null){
        if(line.contains("Player")){
            if(line.contains("won")){
                wonCounter++;
            }else{
                lostCounter++;
            }
        }
    }

    System.out.println("The total times played is: " + (wonCounter+lostCounter));
    System.out.println("The total times won is: " + wonCounter);
    System.out.println("Return Players value is: " + (wonCounter+lostCounter)*100.0/wonCounter);

} catch (IOException e) {
    e.printStackTrace();
}

输出：

The total times played is: 8
The total times won is: 4
Return Players value is: 200.0
