LocalDate backToWork = today.with(NEXT_WORKDAY);

Note that the parameter of the lambda expression has type Temporal, and it must be cast to LocalDate. You can avoid this cast with the ofDateAdjuster method that expects a lambda of type UnaryOperator<LocalDate>.

TemporalAdjuster NEXT_WORKDAY = TemporalAdjusters.ofDateAdjuster(w -> {

LocalDate result = w; // No cast

do {

result = result.plusDays(1);

} while (result.getDayOfWeek().getValue() >= 6);

return result;

});
