Can someone tell me why I'm getting Java error cannot invoke add(int) on array type int on the
bold line? I need this method to calculate median based on file that will be input in a different
method. Do no change to a main method as I need to reserve that to only have a contructor.
public int Problem7(File file) throws FileNotFoundException {
int[] listInt;
try {
Scanner scanner = new Scanner(file);
while (scanner.hasNextLine()) {
String value = scanner.nextLine();
listInt.add(Integer.parseInt(value));
System.out.println(value);
}
scanner.close();
} catch (Exception ex) {
ex.printStackTrace();
}
Arrays.sort(listInt);
int middle = listInt.length/2;
int median = 0;
if (listInt.length%2 == 1)
median = listInt[middle];
else
median = (listInt[middle-1] + listInt[middle]) / 2;
return median;
}}.
