EOFException - how to handle?

EOFException - how to handle?

I'm a beginner java programmer following the java tutorials.
I am using a simple Java Program from the Java tutorials's Data Streams
Page, and at runtime, it keeps on showing EOFException. I was wondering if
this was normal, as the reader has to come to the end of the file
eventually.
import java.io.*;
public class DataStreams {
static final String dataFile = "F://Java//DataStreams//invoicedata.txt";
static final double[] prices = { 19.99, 9.99, 15.99, 3.99, 4.99 };
static final int[] units = { 12, 8, 13, 29, 50 };
static final String[] descs = {
"Java T-shirt",
"Java Mug",
"Duke Juggling Dolls",
"Java Pin",
"Java Key Chain"
};
public static void main(String args[]) {
try {
DataOutputStream out = new DataOutputStream(new
BufferedOutputStream(new FileOutputStream(dataFile)));
for (int i = 0; i < prices.length; i ++) {
out.writeDouble(prices[i]);
out.writeInt(units[i]);
out.writeUTF(descs[i]);
}
out.close();
} catch(IOException e){
e.printStackTrace(); // used to be System.err.println();
}
double price;
int unit;
String desc;
double total = 0.0;
try {
DataInputStream in = new DataInputStream(new
BufferedInputStream(new FileInputStream(dataFile)));
while (true) {
price = in.readDouble();
unit = in.readInt();
desc = in.readUTF();
System.out.format("You ordered %d" + " units of %s at
$%.2f%n",
unit, desc, price);
total += unit * price;
}
} catch(IOException e) {
e.printStackTrace();
}
System.out.format("Your total is %f.%n" , total);
}
}
It compiles fine, but the output is:
You ordered 12 units of Java T-shirt at $19.99
You ordered 8 units of Java Mug at $9.99
You ordered 13 units of Duke Juggling Dolls at $15.99
You ordered 29 units of Java Pin at $3.99
You ordered 50 units of Java Key Chain at $4.99
java.io.EOFException
at java.io.DataInputStream.readFully(Unknown Source)
at java.io.DataInputStream.readLong(Unknown Source)
at java.io.DataInputStream.readDouble(Unknown Source)
at DataStreams.main(DataStreams.java:39)
Your total is 892.880000.
From the Java tutorials's Data Streams Page, it says:
Notice that DataStreams detects an end-of-file condition by catching
EOFException, instead of testing for an invalid return value. All
implementations of DataInput methods use EOFException instead of return
values.
So, does this mean that catching EOFException is normal, so just catching
it and not handling it is fine, meaning that the end of file is reached?
If it means I should handle it, please advise me on how to do it.
Thanks for any answers I might recieve.
