在Java中如何将两个输出作为函数的输入

我正在

Java

中创建一个程序，它读取文本文件并显示各种输出，例如

total played

和

total won

三个输出中的两个我必须完美地显示工作，即

总播放次数

和

总赢得次数

，但我不能让最后一个工作，即

返回玩家

，它需要

总播放次数

和

总赢得次数

来产生输出

我得到的是：

List<Double> RP = data.RegexCheck(fileData.toString(), 
        "(Return Players: £) (totalPlayed/totalWon)*100",2);

//ReturnPlayers
double ReturnPlayers = 0;
for(double d : RP){
    ReturnPlayers+= d;
}

而输出的编写方式是

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);

它正在工作，但最终输出

RP

没有显示任何内容，只有

0.0

，我觉得它应该显示一个数字，因为它需要两个输出，分别显示数字，

1240

和

320

，然后乘以100，应该显示

387.5

myFile.txt

的一个例子是

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

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

我觉得这里缺少osme信息。什么是

RegexCheck

执行和返回？顺便说一句：

RegexCheck

根据java惯例不是一个方法名。您能再显示一些代码吗？你在哪里读文件，在哪里写输出？为什么它不工作？您是否收到异常（以及哪一个）？@Janar我已经编辑了问题请尝试将RP打印到控制台-列表是否包含值？

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