Equivalent of continue keyword in Java stream?

  for (final Prices ppr : prices) {
    if (!currency.getCode().equals(ppr.getCurrency().getCode())) {
      continue;
    }
    return ppr.getPrice();
  }

Can the code above be converted into Java stream code? I am getting an error with the continue keyword...

Just to expand on the provided answer you can also do

return prices.stream()
     .filter(ppr -> currency.getCode().equals(ppr.getCurrent().getCode()))
     .findFirst()
     .orElse(/* provide some default Price in case nothing is returned */);

instead of .findFirst().get() which returns the value which should not be empty. So it assumes there will be some data returned. With the orElse statement you can provide a default value in case nothing is returned.

return prices.stream()
     .filter(ppr -> currency.getCode().equals(ppr.getCurrent().getCode()))
     .findFirst()
     .orElseThrow(NoSuchElementException::new);
