For a project, we need to read a text file, that contains an integer
value on every line. We would like to store the integer values in an
array (the first integer being stored in arrayname[1]). Does anybody
have an idea how to write such a program?

We are grateful for any help we get! Thank you very much in advance.

Here is a quick hack. The lines are read into an arraylist which is
then copied to an array. The first integer is stored in arr[0] i.e.
integer k is stored in arr[k-1]. If thats not what you want, you can
fix it easily.

BufferedReader in = new BufferedReader(new
FileReader("data.txt")) ;
String line = "" ;
ArrayList nums = new ArrayList() ;
while((line = in.readLine())!=null){
int num ;
try{
num = Integer.parseInt(line) ;
nums.add(new Integer(num));
}catch(NumberFormatException e){}
}
int[] arr = new int[nums.size()] ;
for(int i = nums.size() ; --i>=0 Wink

{
arr[i] = ((Integer)nums.get(i)).intValue() ;
}
