ExceptionEater with Optional

ExceptionEater.java

public class ExceptionEater {
  
  private static final Logger log = //TODO Create Logger

  public static <T> Optional<T> swallowNPE(Supplier<T> producer) {
    try {
        return Optional.ofNullable(supplier.get());
    } catch(NullPointerException npe) {
      log.info("NullPointerException being swallowed", npe);
      return Optional.empty();
    }
  }

}

Then you can do this:

ExceptionEater.swallowNPE(this::getPackageIsLargeSchool).ifPresent(userSettings::setPackageIsLargeSchool);

If you want to be really cool, you can do this method:

public static <T,U extends T> Optional<U> applyIfNoNPE(Supplier<U> producer, Consumer<T> consumer) {
  Optional<U> result = ExceptionEater.swallowNPE(producer);
  result.ifPresent(consumer);
  return result;
}

Then you can do this:

applyIfNoNPE(this::getPackageIsLargeSchool, userSettings::setPackageIsLargeSchool);
