DateTimeFormatter to serialize LocalDate as ordinal 1st/2nd/3rd of a month [duplicate]

This question already has an answer here:




  • Printing date in java with ordinal characters [duplicate]

    1 answer




I'd like to display LocalDate as:



first day: 1st;

second day: 2nd;

third day: 3rd;

all rest days: Nth.


e.g. 1980-10-1 as 1st Oct 1980



I'm able to serialize it excluding the first 3 days using DateTimeFormatter.ofPattern("dth MMM yyyy").
Since the first 3 days have a different pattern than the rest days, how to construct the formatter to serialize also the first 3 days?

here is what you are searching : https://docs.oracle.com/javase/8/docs/api/java/time/format/DateTimeFormatterBuilder.html#appendText-java.time.temporal.TemporalField-java.util.Map-



and here is an exemple :



DateTimeFormatterBuilder builder = new DateTimeFormatterBuilder();

Map<Long, String> mapToRoman = new HashMap<>();

mapToRoman.put(1L, "1st");

mapToRoman.put(2L, "2nd");

mapToRoman.put(3L, "3rd");

// continue to map all available days in a month

builder.append(DateTimeFormatter.ofPattern(" MM yyyy", Locale.US));

DateTimeFormatter formatter = builder.toFormatter();

Can a sorcerer learn a 5th-level spell early by creating spell slots using the Font of Magic feature?

Image
28 6 $begingroup$ Per the Font of Magic feature, sorcerer can use Flexible Casting to create 5th-level spell slots at level 7, even though they are not typically available until level 9. You can transform unexpended sorcery points into one spell slot as a bonus action on your turn. The Creating Spell Slots table shows the cost of creating a spell slot of [5th level is 7] If such a sorcerer levels up while still having this 5th-level spell slot, can they choose a 5th-level spell as the spell they gain upon levelling up? The Spellcasting feature states: Additionally, when you gain a level in this class, you can choose one of the sorcerer spells you know and replace it with another spell from the sorcerer spell list, which also must be of a level for which you have spell slots.

Does disintegrating a polymorphed enemy still kill it after the 2018 errata?

Image
up vote 13 down vote favorite 1 After the 2018 errata, the disintegrate spell description now reads: A creature targeted by this spell must make a Dexterity saving throw. On a failed save, the target takes 10d6 + 40 force damage. The target is disintegrated if this damage leaves it with 0 hit points. If you were to polymorph an enemy into a rat and then disintegrate it, would the enemy be disintegrated or would it just return to its original form? I know that for Druids, it’s not an instant kill anymore, but is this the case for polymorph as well? dnd-5e spells polymorph errata share | improve this question edited 18 hours ago

A Topological Invariant for $pi_3(U(n))$

Image
3 3 $begingroup$ Recently, I saw a construction of topological invariant for $pi_3(U(n))$ with $ngeq 2$ : $$ N=frac{1}{24pi^2}int_{S^3} d^3x epsilon^{ijk} Tr[(U^{-1}partial_{x_i}U)(U^{-1}partial_{x_j}U)(U^{-1}partial_{x_k}U)] , $$ where $Uin U(n)$ depends on $boldsymbol{x}=(x_1,x_2,x_3)in S^3$ , $epsilon^{ijk}$ is the Levi-Civita symbol, $i,j,k=1,2,3$ , and the duplicated indexes are summed over. It is claimed that $N$ is an integer, but why? Update 02/02/2019 I think I got an argument for $n=2$ . In this case, $U=e^{i varphi} q$ with $qin SU(2)$ . Due to the trace and the Levi-Civita symbol in $N$ , $varphi$ does not contribute to $N$ . As $Tr[q^{dagger}partial_i q]=0$ and $(q^{dagger}partial_i q)^{dagger}=-q^{dagger}partial_i q$ , $q^{dagger}partial_i q$ in geneeral has the form $q^{dagger}partia
