Finding MAX value from "file.txt"

I'm trying to find the MAX value for...let's say 600 integers from "file.txt" by using an array. And oh, I've only learn until array so far.

"file.txt" contains like this:
2.3
3.4
6.0
...

Here's what I have so far:

Code:

---

public static void main(String[] args)throws FileNotFoundException{
     
        Scanner console = new Scanner(System.in);
       
        System.out.print("Please enter your file name: ");
        String name = console.nextLine();
        Scanner input = new Scanner(new File(name));       
                       
                int totalNum = input.nextInt();
                System.out.println("There are " + totalNum + " in your file.");
                                           
                double[] count = new double[1000];  //Putting list of integers from file into an array?
                int i = 1;
                while (input.hasNextDouble()){
                        count[i++] = input.nextDouble();
                }
                       
                double max = getMaximum(count);      //Calling getMaximum
                System.out.println("Max: " + max);
}
public static double getMaximum(double[] count){
        double max = 0;
        for(int i = 1; i <= count.length; i++){
                  if(count[i] > max){
                          max = input[i];
                }
        }
        return max;
}

What is the question?

Does your code compile? If you cannot understand a compiler message, copy and post the entire thing. Does the program show unwanted behaviour at runtime? including runtime exceptions or other unexpected output? In that case describe both the actual and the expected behaviour.

Oh oops, well, there are no errors but the code won't print the MAX value (double value).

Code:

---

if([b]count[/b][i] > max){
    max = [b]input[/b][i];
}

---

This doesn't look right - but if the code actually compiled it's hard to say without seeing the whole code. Also, what is the output?

-----------------

It strikes me that getMaximum() works it's way through the array looking at one element at a time. It might be a better idea not to use this method as-is but, rather, do something similar to the values in the file: ie don't make an array, just keep track of the biggest value seen so far as you read the file.
