title: Write and Read binary file
body: <p>I have a test: Write number from 50000 to 60000 to file with any format, then read this data to original number (<strong>file size limit 20kb</strong>) and <strong>cannot use writeShort() method to write or read</strong>. But i cannot read file to original number, my code below:</p>
  <p>This is write</p>
  <pre><code> DataOutputStream out = new DataOutputStream(new FileOutputStream(&quot;D:\\mydata2.txt&quot;));
              for (int i = 50000; i &lt;= 60000; i++) {
                  out.write(i);//write() just write 8-bit
              }
              out.close();
  </code></pre>
  <p>This is read</p>
  <pre><code>DataInputStream in = new DataInputStream(new FileInputStream(&quot;D:\\mydata2.txt&quot;));
      int i=0;
      while (in.available() &gt; 0) {
          System.out.print(in.readUnsignedByte()+&quot; &quot;);
      }
      in.close();
  </code></pre>
