问题描述
我对如何将文件的输出存储到数组有疑问。就我而言,我试图将文件中的所有日期存储到数组中。对于我这样做的方式,编译器抱怨不是语句。我怎样才能解决这个问题?任何帮助将不胜感激。下面是我的代码(错误行之前是反斜杠):
I have a question on how to store output from a file into an array. In my case, I am trying to store all the date in a file into an array. For the way that I did it, the compiler complains "not a statement". How can I fix this? Any help will be greatly appreciated. Below is my code (the line of error is preceded by backslashes):
double token[] = new double[9];
File filename = new File("/Users/timothylee/gravity1.txt");
Scanner inFile = new Scanner(filename);
while(inFile.hasNext()){
//////////////// token[] = inFile.nextDouble();
System.out.println(token);
}
inFile.close();
如果需要,这里是文件:
If needed, here is the file:
gravity1.txt:
3.70
8.87
9.79
3.70
24.78
10.44
8.86
11.13
0.61
推荐答案
double token[] = new double[9];
int i = 0;
while(inFile.hasNext()){
token[i] = inFile.nextDouble();
System.out.println(token);
i++;
}
inFile.close();
这是假设文件只有9行。
This is assuming the file only has 9 lines.
