 if (date < 1 || date > 31) {

                        System.out.println("Please Enter a valid day \n a day can't be smaller than 1 and bigger than 31");
                        System.out.println("Please enter your birth date format like that \n XX \n YY \n MMMM ");

                                            }

so im assuming below these checks you want to print the zodiac sign ok so hold on let me write it

this is mistifiOP•2mo ago

okay no problem ı have 2 more days to finish it after that ı will do reverse string program fortunately ı found a tutorial

ayylmao123xdd•2mo ago

you can do something like this

Map<Integer, String> monthMessages = Map.ofEntries(
                Map.entry(1, "a"),
                Map.entry(2, "b"),
                Map.entry(3, "c"),
                Map.entry(4, "d"),
                Map.entry(5, "e"),
                Map.entry(6, "f"),
                Map.entry(7, "g"),
                Map.entry(8, "h"),
                Map.entry(9, "i"),
                Map.entry(10, "j"),
                Map.entry(11, "k"),
                Map.entry(12, "l")
        );

Map<Integer, String> monthMessages = Map.ofEntries(
                Map.entry(1, "a"),
                Map.entry(2, "b"),
                Map.entry(3, "c"),
                Map.entry(4, "d"),
                Map.entry(5, "e"),
                Map.entry(6, "f"),
                Map.entry(7, "g"),
                Map.entry(8, "h"),
                Map.entry(9, "i"),
                Map.entry(10, "j"),
                Map.entry(11, "k"),
                Map.entry(12, "l")
        );

and then oh yea replace the letters with ur zodiac sign thing and then if you wanna print it just do

System.out.println("Your zodiac sign is " + monthMessages.get(month));

System.out.println("Your zodiac sign is " + monthMessages.get(month));

i saw month is your variable so i put it there

this is mistifiOP•2mo ago

do ı need any other methods for program

ayylmao123xdd•2mo ago

no try this

 public  static void main(String[] args){
          //month messages here

           LocalDate today = LocalDate.now();

                year = scanner.nextInt();


                    if (date < 1 || date > 31) {

Madjosz•2mo ago

Zodiac sign does not change on month though. It's somewhere around the 21st but different for each sign.

ayylmao123xdd•2mo ago

oh yea lmao i forgot have to tweak it a bit then

this is mistifiOP•2mo ago

so ı oly need to use date variable also how ı am going to do the math between the time methot and our ınputted year it says you can not do that they are diffrenent types

ayylmao123xdd•2mo ago

which thing we will use day and month ill show how in a second

this is mistifiOP•2mo ago

currentYear-year=user age it is not implemented yet but ı need it

ayylmao123xdd•2mo ago

oh user age its just let me write it

        int userAge = Period.between(LocalDate.of(day, month, year), LocalDate.now()).getYears();

        int userAge = Period.between(LocalDate.of(day, month, year), LocalDate.now()).getYears();

this is user age i named it day but in your code its date

this is mistifiOP•2mo ago

is it built in method our teacher stated that you can not use built in methots

ayylmao123xdd•2mo ago

interesting did he say if you can use localdate.now its also a built in method

this is mistifiOP•2mo ago

only for getting current time he said

ayylmao123xdd•2mo ago

ok

this is mistifiOP•2mo ago

ı dont know wht it is so hard

ayylmao123xdd•2mo ago

ok question do you want longer answer or simpler answer for zodiac sign

this is mistifiOP•2mo ago

ı think the longer answer ı need to push my limits

ayylmao123xdd•2mo ago

did you have enums in school

this is mistifiOP•2mo ago

yeah in todays class we looked into enums they are reference types like arrays but improved arrays

ayylmao123xdd•2mo ago

so will you be able to explain whats happening when the teacher asks you to explain im asking cuz im thinking whether to show the answer with enums or no or just ifs ill do enums and if its too complex ill show the simple version

this is mistifiOP•2mo ago

enums are just like arrays as ı understand if there is parts that ı do not know i will learn ı am putting 4-5 hours to coding as it is my first year

ayylmao123xdd•2mo ago

ok

ayylmao123xdd•2mo ago

message.txt

ayylmao123xdd•2mo ago

replace your publci static void main with what i put and check it out basically i used enums to create date ranges and since you cant use built in stuff i put it as int otherwise the best idea would be using monthday and then it just compares the range sees if a value is in range and returns the name of that enum

thanks for your help as in my country time is 23.10
