Double不会从int数组中赋值

Question

在我的程序中,我从一个文本文件加载一些自定义变量来使用.这是执行此操作的方法.

public int[] getGameSettings() {
String[] rawGame = new String[100];
String[] gameSettingsString = new String[6];
int[] gameSettings = new int[6];
int finalLine = 0;
int reading = 0;

try{
    // Open the file that is the first 
    // command line parameter
    FileInputStream fstream = new FileInputStream("gameSettings.txt");
    BufferedReader br = new BufferedReader(new InputStreamReader(fstream));
    String strLine;
    //Read File Line By Line
    int line = 0;
    while ((strLine = br.readLine()) != null)   {
    // Store it
    rawGame[line] = strLine;
    line++;
    }
    //Close the input stream
    in.close();
    reading = line;
        }catch (Exception e){//Catch exception if any
    System.err.println("Error: " + e.getMessage());
    }

    for (int a = 0; a < reading; a++) {
        if (!rawGame[a].substring(0,1).equals("/")) {
        gameSettingsString[finalLine] = rawGame[a];
        finalLine++;
        }
    }
    for (int b = 0; b < finalLine; b++) {
    gameSettings[b] = Integer.parseInt(gameSettingsString[b]);
    }
return gameSettings;
}   

我从另一个类调用该方法并将数组保存为gameSettings,然后执行以下操作:

contestedMovementPercent = (gameSettings[1]/100);

有争议的运动总是显示为0.0,即使我打印gameSettings [1]它出现了它应该是什么.contestedMovementPercent是一个双倍.gameSettings是两个类中的int数组.

我需要做某种演员吗？我认为int可以像这样使用.

你要除以int,所以它首先将它计算为int然后将其转换为double.将其更改为gameSettings[1]/100.0将其计算为double.
