Question

How to port this code in Objective-C? Anyone please help.

return data.length != 0 ? new Byte(data[0]) : null;  // In Java  

I am doing it this way, but this does not show the proper result

return datalen!= 0?malloc(sizeof(char) *data[0]) :NULL; //In Objective C it is write java data is byte 

**In obj C** datalen int datalen = sizeof(data)/sizeof(*data);

I am unable to return data value. What is the problem?

You should return a NSData object:

NSData* dataObj = nil;
if (datalen)
        dataObj = [NSData dataWithBytes:data length:1];

return dataObj;
