Java DataInputStream question

hey im reading a binary file of numbers into somthing, problem is I only knew how to read from text files and there is (well I don't think), there is a .eof() in the DataInputStream.
how I i keep reading numbers until i read the end of the input file? I know I can't put:

Code:

---

while (!in.eof) {
...
}

---

DataInput::readInt

Code:

---

try
{
    myInt = dis.readInt()

} catch (EOFException e)
{
    System.err.println("Unexpected end of file!");
    System.err.println(e.toString());
}

---

However, you are better off checking the length of the file before working with it.

Code:

---

File f = new File(filename);
long length = f.length();
