Examples of java.io.DataOutputStream.writeInt()

java.io.DataOutputStream.writeInt()
Writes a 32-bit int to this output stream. The resulting output is the 4 bytes, highest order first, of val. @param val the int to be written. @throws IOException If an error occurs attempting to write to this DataOutputStream. @see DataInput#readInt()

        int c = 0;
        Map.Entry<Long, Integer> e;
        while (i.hasNext()) {
            e = i.next();
            os.writeLong(e.getKey().longValue());
            os.writeInt(e.getValue().intValue());
            c++;
        }
        os.flush();
        os.close();
        tmp.renameTo(file);
