Say I had a file set up like this:
20 88.6
16 71.6
19.8 93.3
18.4 84.3
17.1 80.6
15.5 75.2
14.7 69.7
17.1 82
The two float values are separated by a space, say that the ones on the left are x values and the ones on the right are y values how would I read the file and store the x values in one array and the y values in another?
public static Float[] getData() throws FileNotFoundException {
float data;
List<Float> temps = new ArrayList<Float>();
Scanner inFile = new Scanner(new File("cricket"));
while(inFile.hasNext()) {
data = inFile.nextFloat();
temps.add(data);
}
inFile.close();
for(int i = 0; i<=temps.size(); i++) {
Float[] tempsArray = temps.toArray(new Float[0]);
}
return tempsArray;
}
This is my code so far, I have all of the values in a single array, I'm not sure how to split them up.
