How to know whether we have reached eof while using ObjectInputStream to read a bunch of objects stored in a file.

i have a file named india.txt which contains three objects(Junk) stored using ObjectOutputStream, Now i am reading those objects using the following code snippet

 
objectIn = new ObjectInputStream(new BufferedInputStream(
		    fin = new FileInputStream("c:/Files/india.txt")));

	    while (true) {  // this is not correct. how to check whether we reached end of file
		object = (Junk) objectIn.readObject();  //may throw EOFException if the file pointer is beyond EOF
	    }

Thanks in advance
