Java how to concatenate 0x with variable containing hex?

[jeffbroodwar]

Hi,

I want to concatenate 0x with a variable (dont know what type) to pass it in a byte array. the code below shows the original code :

ORIGINAL CODE :

ioData = new byte[256];

ioData[0] = (byte)0xAA;


the code below illustrates what i want to do....

DESIRED CODE :

ioData = new byte[256];
String strHEX = "FF";


ioData[0] = (byte)0x + strHEX;

This way i can pass any hex value to 0x. The problem is, i can't eliminate the error..... is there a way to achieve this? i'm sure there is right? I'll just need experts like you guys to figure it out and help me with this one... ^^ thanx in advance


Regards,
Jeff

There's no need to prepend "0x" to a String value that represents a hexadecimal
value. Have a look at the Integer.parseIn t(String rep, int radix) method. It
does exactly what you want. Cast the result of this method back to a (byte) and
store it in you byte array.

kind regards,

Jos
