How should I increase the test coverage for this apex controller class - apex

Question

How do I make coverage more than 75% using apex test class for this controller class. I try to write test class for this but, I'm not able to make its coverage as 75 or above 75. I am tried to cover its second method but its covers only 1 line of its try block i.e. Id recordId = hostId; Other part of code is not covered. It is only cover its catch block. So could you help me to make its coverage more than 75.
