Java Utility Methods
1. Conversion
a) Array => String
String modeStr = StringUtils.join(modes, '/')
b) String => Array
String[] modes = StringUtils.split(protocolStr, '/')
2. Bit Ops
a) Check bit
int RADIO_PROTOCOL_A = 0x1; if (radioMode & RADIO_PROTOCOL_A) == RADIO_PROTOCOL_A
b) Set/Unset bit
radioMode = radioMode | RADIO_PROTOCOL_A radioMode = radioMode & ~RADIO_PROTOCOL_A
