POHexadecimal over 7F into String in Java
text
Body
copied!<p>I need to append some hexadecimal characters to my string. I'm trying this:</p> <pre><code>content += Character.toString((char) Integer.parseInt(Integer.toHexString(originalSize).toString(), 16)); </code></pre> <p>And it's working, but when <code>originalSize</code> is over 127 (7F in hex) it returns me two hexadecimal values.</p> <p>For example, doing this:</p> <pre><code>content += Character.toString((char) Integer.parseInt(Integer.toHexString(176).toString(), 16)); </code></pre> <p>The result is: <code>(content hex numbers) C0 B0</code></p> <p>B0 is 176 in hexadecimal, but I don't know how to remove C0. Any suggestions please? Thanks!</p> <p><strong>EDIT</strong>:</p> <p>I want to send an string to a device via Bluetooth Low Energy. I have an string like this:</p> <p>"ABCABC". In hexadecimal is <code>41 42 43 41 42 43</code>. </p> <p>Now, I want to add the format of this string (because the device is waiting for it), so I add it at the end: <code>41 42 43 41 42 43 7E 06 02</code>, where:</p> <ul> <li><code>7E</code>: beggining of the format</li> <li><code>06:</code> number of chars</li> <li><code>02</code>: specifical format given by manufacturer.</li> </ul> <p>I have the main string and I'm adding this three hexadecimal characters by hand.</p> <p><strong>SOLUTION:</strong></p> <p>Based on Devon_C_Miller answer I found my own solution:</p> <pre><code>contentFormated = new byte[originalSize+3]; for(int i=0;i<originalSize;i++){ contentFormated[i] = content.getBytes()[i]; } contentFormated[originalSize] = 0x7E; contentFormated[originalSize+1] = (byte) 0xB0; contentFormated[originalSize+2] = 0x02; </code></pre>
