NumberFormatException.forInputString(s)

Hey Everyone I am new to OpenHab and I am trying to make some binding .I successfully set up IDE and its working fine but when I am trying to run my binding without writing any of my code in it .
@Override
public void handleCommand(ChannelUID channelUID, Command command) {
if (channelUID.getId().equals(CHANNEL_1)) {
while (true) {
System.out.println(“I am in the loop”);
System.out.println(“I ma i”);

        }

    }

}

i just put a break point in front of System.out.println(); its throwing NumberFormatException.forInputString(s) in if (channelUID.getId().equals(CHANNEL_1) in this line
please help me out .i kind of stuck in this please ???
