<@&987246399047479336> please have a look, thanks.

While you are waiting for getting help, here are some tips to improve your experience:

Code is much easier to read if posted with syntax highlighting and proper formatting.

If nobody is calling back, that usually means that your question was not well asked and hence nobody feels confident enough answering. Try to use your time to elaborate, provide details, context, more code, examples and maybe some screenshots. With enough info, someone knows the answer for sure.

Don't forget to close your thread using the command </help-thread close:1027500463647621170> when your question has been answered, thanks.

if its only one of those u can do a few other things,
its a fixed list so enum
and do not let the user type at all, but select it from a list or generate buttons based on the enum
etc

digital kite
latent robin
#

in that case, same trick as with console output

#

user types -> goes trough some validation, if not valid, the scene does not progress

digital kite
#

could you show me the code needed to do that, please?

latent robin
#

nope

digital kite
#

okay, then could you show me methods i coculd get that to work then?

latent robin
#

( i wont, and there a gazillion ways your code could of been made to get this far 😉 )

#

i can talk u trought the process

#

at the moment , u got what exactly ?

digital kite
#

ill send you a picutre

#

i have this so far.

#

and in order for the switch statements to work, i would need a valid input, or if the user inputs an invalid input, I can at least return something telling them that it is invalid

sage scrollBOT
#

Please use this format for posting code:

```java
// Example java program
int value = 5;
System.out.println(value);
```

Which results in:

// Example java program
int value = 5;
System.out.println(value);

For syntax highlighting, you have to add the name of the language after the three backticks, like ```java. Please make sure to use exactly this format, so no space between the backticks and the language name, and a newline before the code starts. If done right, the syntax highlighting will even be applied to your text as you type, before sending.

#

you want me to display liek this, right?

latent robin
#

yeah, else its really not readable

digital kite
#

is there a caommnd i can do

#

to get my code like that?

#

i can paste it

#

but where do i paste it?

latent robin
#

look at what the bot said and do it that way

#

will show like this

digital kite
#

its a message/

#

._.

latent robin
# 
test(foo){bar();}
digital kite
#

how do i enter?

#

it will nota llow me to enter latewards

latent robin
#

read the bot text and insert the code that way, then it becomes readable

digital kite
#

it is notw roking

#

i can get the language working

#

but i canot enter

#

once i apsted my code

latent robin
#

sure u can, type 3 backticks and java

#

`

#

that one

digital kite
#

`

#

that one?

latent robin
#

yeah

#

3 times that, directly followed by java, as mentiond in the bot text ( try with some small code first to get it working )

# 
foo();
digital kite
#

i got the pasting working

#

how do i send it?

#

its nont letting me send

latent robin
digital kite
#

OHHH

#

you need 3 backticks at thee end

#

i see

perfect 🙂

digital kite
#

my bad

latent robin
#

as your skipping alot of java prior to starting with a frontend:

digital kite
#

could you dumb that sentence down for me?

latent robin
#

sure

#

your doing things to fast :p

digital kite
#

as in, progressing too fast?

latent robin
#

yeah

digital kite
#

yeah, well i signed up for a 10 day java beginner lesson for the summer

#

this was day 5

#

so I was just following the curriculum, didn't know it was going too fast

latent robin
#

your trying to learn GUI and java at the same time

digital kite
#

well, the GUI is not really the focus

latent robin
#

works like nothing, but u get stuck really fast

digital kite
#

the insutrctor just mentioned we could incorporate

latent robin
#

the trick to your problem is this

#

place the input in a loop and have it check the sentence each pass

#

and make it exit the loop when its valid ( or a exit condition is met )

digital kite
latent robin
#

yeah, u should know that by now

digital kite
#

if statements?

latent robin
#

loop -> while / for etc

#

if is for condition checking

digital kite
#

oh

#

so could you guide me through this?

latent robin
#

only happens once aswell, if u need repeats, u needs some sort of repetition

digital kite
#

so my main goal, again, here is to make the wrong input of the user exit thee program

#

once it exits, it shoul[d prompt thee user who put in the input that it was wrong,

#

and I am confused how a loop is goinig to accomplsih that

#

does it make the user retype it utnil it is right?

latent robin
#

yup, or untill the exit condition is met ( in your case empty )

digital kite
#

well, not realy empty

latent robin
# 
  if (beginOption.isBlank()) {
            System.err.println("System exited because no value was given");
            System.exit(0);
        }
sage scrollBOT
digital kite
#

correct me if im wrong, because you are much more experienced probably, but the 3 possible inputs the coputer realizes should be movie, book, or game

latent robin
#

your code -> empty = stop program

digital kite
# 
String beginOption = JOptionPane.showInputDialog(null, "please select one of the categories {Movie, Book, Game}");
#

an input dialog

latent robin
#

book -> Book -> bOok -> .....

digital kite
#

if the user does not type one of the three, then i want he code to prompt the user it is not recofized

digital kite
latent robin
#

yep , to reduce to soemthing controlable

digital kite
#

or i could prompt the user to write it in a specific way

digital kite
#

I think i can do that

#

that'll be it for me today

#

thank you.

latent robin
#

sec

#

do this

digital kite
#

?

latent robin
#

make your first input

digital kite
#

mhm..

latent robin
#

then write the validation

#

if its not valid, paste the code to enter the text again

#

if u get that working, then read up on how loops work

#

( easy adjust and it will work as intended )

#

so input -> not valid -> input

#

then read up on loops

digital kite
#

ok

  1. get the ignore case down [control]
  2. input
  3. validation/loop code to get down to the proper input i want the user to put in
#

correct?

latent robin
#

step 0 -> get input

digital kite
#

right.

latent robin
#

ignore the loop at the moment as u do not know it

#

write this

#

ask input
validate

#

if not correct, ask input again

#

and then read up on loops

digital kite
#

how do i validate

#

?

latent robin
#

If u get that working, the skeleton for the loop is in place

#

easiest, place them in an array and go over them

#

( for your knowledge )

digital kite
#

ok

#

alright

#

ill go ahead and start working on it

#

so do i close this post?

latent robin
#

u can, or u can leave it open incase u run into more problems

digital kite
#

i have an uncle that will become available later, I think i can close it now

latent robin
#

( keep in mind that newer joiners will need to catch up on all the above )

digital kite
#

okay
