NullPointerException

Posted by Jonathan Marks on November 20, 2000 at 3:35 AM

Does anyone know why a NullPointerException might be thrown. I am trying to copy the details from an array into a text file using the following code;

try
{FileWriter fw = new FileWriter "C:\\Java_Files\\Customers_Java.txt");
PrintWriter pw = new PrintWriter(fw);

for (i = 1; i <= customers_held; i++)
{
pw.println(i);
pw.println(name[i]);
pw.println(street[i]);
pw.println(town[i]);
pw.println(county[i]);
pw.println(postcode[i]);
}
fw.close();
}catch(FileNotFoundException e){
System.out.println("Error: Can't find file specified!");
}catch(IOException e){
System.out.println("I/O Error: " + e);
}

Any help would be appreciated!
Many thanks
