Hi,


I have this hex string, "1EA23", I would like to put this hex string into a byte array...
For example...

String hexString = "1EA23";
byte byteArray[] = new byte[4];

the value of byteArray should be...
byteArray[0] = (byte)0;
byteArray[1] = (byte)0x01;
byteArray[2] = (byte)0xEA;
byteArray[3] = (byte)0x23;

How can I do this??  I try to do it with substring...but it seems not work well...help please~~~~
