i'm writting a numerology report for my programming class and i think i got all the code but after i run the program and enter a date it wont tell me the results. i have tried everything but no luck also if i run the program and i enter a wrong date and then a correct date the program just keeps asking me to enter another date instead of telling me the results

for example:

Enter the birth date (mm/dd/yyyy):7 / 27 / 1981

after entering the date is should display "Welcome to the Numerology report for 7/27/1981: and tell me my fortune BUT INSTEAD i wont display anything.


also

lest say i enter 0 / 10 / 2000
then it displays:Bad month:0 which is good but if i enter a good date after that for example 2 / 28 / 2007 then the program just keeps asking me to enter a birth date again and again.

and i have no idea what is wrong

You need to put your original questions/prompts inside your main loop. Once you get a bad date you never give the user the option to turn the 't' flag to 45.

If you do that, you should also only have this code once in the loop.

month=input.nextInt();
symbol=input.next().charAt(0);
day=input.nextInt();
symbol=input.next().charAt(0);
year=input.nextInt();

so if i do that do i put the code

month=input.nextInt();
symbol=input.next().charAt(0);
day=input.nextInt();
symbol=input.next().charAt(0);
year=input.nextInt();

at the end of the loop?

The problem here is the person has to press enter 5 times for example:
9*enter*/*enter*19*enter*/*enter*1994*enter* (It's my birthday, don't judge me )

Do you see the problem? It's asking for each input by itself so the user has to put in the month, then press enter, then the symbol, then press enter etc etc. I sorta redid your whole code (I have too much spare time )
