byte[] bytes = new BigInteger("1EA23", 16).toByteArray();

<div>
&gt; byte[] bytes = new BigInteger(&quot;1EA23&quot;, 16).toByteArray();<br />
This would an array that is only 3 in length.

Hi,<br />
<br />
<br />
I have this hex string, &quot;1EA23&quot;, I would like to put this hex string into a byte array...<br />
For example...<br />
<br />
String hexString = &quot;1EA23&quot;;<br />
byte byteArray[] = new byte[4];<br />
<br />
the value of byteArray should be...<br />
byteArray[0] = (byte)0;<br />
byteArray[1] = (byte)0x01;<br />
byteArray[2] = (byte)0xEA;<br />
byteArray[3] = (byte)0x23;<br />
<br />
How can I do this?? &nbsp;I try to do it with substring...but it seems not work well...help please~~~~<br />
<br />
<br />

Convert a hex string to byte array

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
