How to parse text file
问题
demo.txt :<br/>
FD1,true,102400,4000,0.01,103,83.25 <br/>
FD0,false,102400,4000,0.01,103,83.25
我想访问每一行的第一个元素，然后从每一行中访问每个元素，并将其作为参数传递给函数createFogDevice来执行某些操作。
类似于 createFogDevice(FD1,true,1024,4000,0.01,103,83.25)
有人可以帮忙编写这个代码吗？
英文:
demo.txt :<br/>
FD1,true,102400,4000,0.01,103,83.25 <br/>
FD0,false,102400,4000,0.01,103,83.25
I want to access each line 1st then from each line i want to access each element and pass this as parameter to a function createFogDevice to perform some action.
like createFogDevice(FD1,true,1024,4000,0.01,103,83.25)
Can anybody help how we can write code for this ?

Scanner scanner = new Scanner(new File());
while (scanner.hasNextLine()) {
String currentLine = scanner.nextLine();
String[] dataPoints = currentLine.split(",");
String a = dataPoints[0];
boolean b = Boolean.parseBoolean(dataPoints[1]);
// ....
createFogDevice(a, b, c/*...*/);
}
英文:
Scanner scanner = new Scanner(new File());
while(scanner.hasNextLine()) {
String currentLine = scanner.nextLine();
String[] dataPoints = currentLine.split(",");
String a = dataPoints[0];
boolean b = Boolean.parseBoolean(dataPoints[1]);
// ....
createFogDevice(a,b,c/*...*/);
}

尝试这个：
try (Stream<String> stream = Files.lines(Paths.get("demo.txt"))) {
stream.forEach(ob -> createFogDevice(ob.split(",")));
} catch (IOException e) {
e.printStackTrace();
}
另外，您可以修改createFogDevice() 方法以传递字符串数组作为参数：
private static void createFogDevice(String[] inputParams) {
// 在这里编写您的代码
}
英文:
Try This :-
try (Stream<String> stream = Files.lines(Paths.get("demo.txt"))) {
stream.forEach(ob->createFogDevice(ob.split(",")));
} catch (IOException e) {
e.printStackTrace();
}
Also you can modify createFogDevice() method to pass Array of String as argument :-
private static void createFogDevice(String[] inputParams) {
// your code goes here
}
