```
public static Set<NurseViewPrescriptionWrapper> create(final Set<NurseViewPrescriptionDTO> nurseViewPrescriptionDTOs) {
  return nurseViewPrescriptionDTOs.stream()
      .map(new Function<NurseViewPrescriptionDTO, NurseViewPrescriptionWrapper>() {
        @Override
        public NurseViewPrescriptionWrapper apply(NurseViewPrescriptionDTO input) {
          return new NurseViewPrescriptionWrapper(input);
        }
      })
      .collect(Collectors.toSet());
}

```

I convert above code to java 8 lamda function as below. 

```
public static Set<NurseViewPrescriptionWrapper> create(final Set<NurseViewPrescriptionDTO> nurseViewPrescriptionDTOs) {
  return nurseViewPrescriptionDTOs.stream()
      .map(input -> new NurseViewPrescriptionWrapper(input))
      .collect(Collectors.toSet());
}

```

Now, I am receiving sonar issue, like `Lambdas should be replaced with method references` , to '->' this symbol. How i can fix this issue ?
