Question

My problem:

I have code in Java that I need to port to Objective-C where

Obj[i] is byte[],  
Buffer is byte[],   
index is int

In my Objective C I have declared

Obj[i] is char**    
Buffer is char*  
index is int

and I am not able to convert this line buffer[index] = ((Byte)obj[i]).byteValue();

case cw_BYTE_obj:

if(obj[i] == NULL)
{

    buffer[index] = 0x01;
    index++;
    buffer[index] = ((Byte)obj[i]).byteValue();
    index++;
}

orginal java code

case cw_BYTE_obj: 
if(obj[i] == null){
buffer[index] = 0x00;
index++;
}else{
buffer[index] = 0x01;
index++;
buffer[index] = ((Byte)obj[i]).byteValue();
index++;
}
break;

First, why is obj a char** in obj-c when it’s a byte[] in java?
Anyhow, so you want a char to go into buffer[index], and obj[i] is char** so is probably a pointer to a char* ?? Depending on what you’re putting into obj, you will probably be after something like buffer[index] = *(obj[i]);
