Reading/writing doubles in primitive format

Question

I created an array of doubles using random.nextDouble(). Then wrote the array to a file using a primitive format. When trying read the data and put it back into an array, it gives me a java.io.EOFException. Here's the code I used to write and read the data, not the entire program, just the code used for it. Any help is much appretiated; I've been working on this for hours.
          try {
               DataOutputStream output = new DataOutputStream(new BufferedOutputStream(new FileOutputStream("dblPrim.data")));
               start = System.currentTimeMillis();
               for(count=0; count<arraysize; count++){
                    output.writeDouble(anarray[count]);
                    ++count;
               end = System.currentTimeMillis();
               time = end - start;
               displayTime(time, 1);
               output.close();
               average = 0;
               total = 0;
               start = 0;
               time = 0;
               end = 0;
               double[] anarray2 = new double[arraysize];
               DataInputStream input = new DataInputStream(new BufferedInputStream(new FileInputStream("dblPrim.data")));
               start = System.currentTimeMillis();
               for (count = 0; count<arraysize; count++){
                    System.out.println("" + input.readDouble());
                    anarray2[count] = input.readDouble();
                    total = total + anarray[count];
               end = System.currentTimeMillis();
               time = end - start;
               average = total / anarray.length;
               displayAverage(average, 2);
               displayTime(time, 2);
               input.close();

Answer 1

take a look at your second 'for' loop:
for (count = 0; count<arraysize; count++){
System.out.println("" + input.readDouble());
anarray2[count] = input.readDouble();
total = total + anarray[count];
}you are calling readDouble() TWICE for each iteration, so you will run out of doubles to read too quickly!!
