Reading an array from a file

How do I initialize an array that has been called from a file? There will be 5 values in the array. So should my file "input.dat" have:
5 (number of values)
4 (value)
6 (value)
7 (value)
2 (value)
7 (value)

Example:
BufferedReader br = new BufferedReader(
new FileReader("input.dat"));

and I'm lost after that.

Thanks,
Bud

Some progress has been made...

I've been able to create the text file with data, and create the array. The thing that I cannot get it to do is to use the first number in the file as the size of the array. The array in the text file is a set of scores, and there are 5 scores. The first number is supposed to set the size of the array, so the first number is 5, followed by the actual 5 values in the array.

Is this possible? If so, how would I setup the declaration/initialization statement?
Right now I have:

BufferedReader fr = new BufferedReader (new FileReader ("goals.txt"));int score [] = new int [5];
// read all scores from the files goals.txt
for (int i = 0 ; i < 5 ; i++)
{

goal [i] = Integer.parseInt(fr.readLine ());
}
// display the nine goals on the screen
System.out.print ("The goals are: ");
for (int i = 0 ; i < 5; i++)
{
if (i < 4)
// add a comma if not the last hole
System.out.print (score [i] + ", ");
else
// no comma and a prinln for the last output
System.out.println (score [i]);
} // end loop
