If there is something wrong with it, what is the most natural way of fixing it? public void g(String s) { if (s == null) { NullPointerException e = new NullPointerException(Invalid Input); throw e; } } Nothing wrong with the method Method declaration needs a throws clause: public void g (String s) throws NullFcinterException {... Method body needs a try/catch: if (s == null) { NullPointerExceptione = new NullFcinterException(Invalid Input); try { throw e; } catch (NullFcinterException e1) { e1.printStacfcTrace() ; } }
