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.

You need to import ArrayList

You can literally hover with ur mouse over and Intellij do it for u

[hearty pendant]

it dosent work to import ArrayList?

what does not work

whats the error

screenshot

ur main method is empty

its where the code starts to run

u running nothing basically

[silver bear]

well, whatever u want to do

u have to understand ur code

we can't write it for u

the main method is where java starts executing code when u run it

it runs it top to bottom

once main is done, the program ends

so with an empty main methods, ur program doesnt do anything at all

[silver bear]

yes

im surprised how much code u wrote without ever executing it

thats not how people write code normally

[hearty pendant]

prob a template from teacher

[silver bear]

usually code is written step by step and constantly executed to check whether it works

what's unclear to u based on what has been explained by us

[hearty pendant]

That year is already close to over, so u were in ur school for 1 year and you still dont know anything, if you never hear what is said in lesson and only on homework u ask someone to do it for u its not how that works

if u dont know a main method u know nothing about Java at all

so u will never finish a hangman game if you dont start to really learn

You can view that course, should be enough for school work: https://www.youtube.com/watch?v=xk4_1vDrzzo&t=293s

we cant explain whole Java to u in couple minutes, just watch the first 30min-1h of the course then you will be able to finish that

And also redo what the guy does in video if you want that it stays in ur head

no we cant, as i said we cant explain whole Java to you. And if we do the homework for you, you will never start to learn self

If you on a IT school and dont wanna learn Java, then you should switch school

Do you even know what the hangmanWord method does

or are you just shifthing code all over the place and hope something will work

Is that bringing the whole application to run a hangman game

im asking you if that makes a hangman game, you said self it chooses a word, but u not only want to choose a word

read what other methods doing

and then call the right one

yes

hell no, just the call to them, not smash all the code in the main method

your sentence does 0 sense but i think right what u prob mean

u just need to call 1 single method which will run the whole game, just read what all methods doing

[silver bear]

now, ur java program, when executed, will run the hangmanWord method

nothing else

most likely not what u wanted to do

what about all ur other methods

begin and game

are they not important?

if u dont call them, they are not executed

think again

and u really have to understand the code

not just do random stuff

and sorry for the harsh words. ( @hearty pendant try to give the reality check a bit more friendly next time 😄 )

[snow raft]

I'm impressed tbh

[silver bear]

mind sharing ur main method

[dense terrace]

I uploaded your attachments as Gist.

[silver bear]

why are u calling hangmanWord in ur main method

seems to be totally wrong

but do u also understand it

otherwise ur just writing what im saying

and that wont help u

alright

the next problem is that ur running into this scanner issue here:

[dense terrace]

Mixing any nextXXX method with nextLine from the Scanner class for user input, will not ask you for input again but instead result in an empty line read by nextLine.

To prevent this, when reading user input, always only use nextLine. If you need an int, do

int value = Integer.parseInt(scanner.nextLine());

instead of using nextInt.

Assume the following:

Scanner scanner = new Scanner(System.in);

System.out.println("Enter your age:");
int age = scanner.nextInt();
System.out.println("Enter your name:");
String name = scanner.nextLine();

System.out.println("Hello " + name + ", you are " + age + " years old");

When executing this code, you will be asked to enter an age, suppose you enter 20.
However, the code will not ask you to actually input a name and the output will be:

Hello , you are 20 years old.

The reason why is that when you hit the enter button, your actual input is

20\n

and not just 20. A call to nextInt will now consume the 20 and leave the newline symbol \n in the internal input buffer of System.in. The call to nextLine will now not lead to a new input, since there is still unread input left in System.in. So it will read the \n, leading to an empty input.

So every user input is not only a number, but a full line. As such, it makes much more sense to also use nextLine(), even if reading just an age. The corrected code which works as intended is:

Scanner scanner = new Scanner(System.in);

System.out.println("Enter your age:");
// Now nextLine, not nextInt anymore
int age = Integer.parseInt(scanner.nextLine());
System.out.println("Enter your name:");
String name = scanner.nextLine();

System.out.println("Hello " + name + ", you are " + age + " years old");

The nextXXX methods, such as nextInt can be useful when reading multi-input from a single line. For example when you enter 20 John in a single line.

also, u shouldnt create two scanners. create one and reuse it

in fact, u already have one prepared for reusing

https://i.imgur.com/BX3UQal.png

back to u not fully understanding ur own code. which is the main issue here

no

re-read what i said please

[hearty pendant]

Hell no, if people not wanna learn i wont help them, im not a babysitter. You should be the same and say them in thier face that they need to learn or they will suck for rest of thier lifes

[silver bear]

if u cant tell someone friendly that they fucked up, without them feeling like absolute shit, then please rather not say anything at all and let someone else handle it, thanks

this can be done in a friendly way as well

[hearty pendant]

They need to feel shit to understand that they do something pretty wrong and need to change something

No one will change if u babysit him

[silver bear]

i disagree. we can discuss this in DM if u want.

its fine. ur doing great. im sure u will be able to finish the hangman game if u put in some effort now and stick with us and the guidance 🙂

yeah. but u got enough time to finish this task still

in any case, we are here to help and assist u 🙂

in fact, after uve fixed the two scanner issues explained above, u will be moving forward quite a bunch already

not sure i follow

have u fixed the scanner issues already?

please reshare

well. seems u misunderstood me

u didnt do any of what i said

each time someone calls the begin method, ur creating a new scanner

same with the game method

thats bad

they can interfere with each other and mess up ur input

ur whole program should use a single scanner and reuse it everywhere

the program was already prepared to do so

with the static scanner field at the top

which u were supposed to use instead

but u just killed it

and u didnt fix the issue with nextInt() that the bot explained

leading to ur inputs not being recognized by the scanner

and then use it instead of creating other scanners

it feels like ur only reading 20% of my sentences

and then use it instead of creating other scanners

ur whole program should use a single scanner and reuse it everywhere

which u were supposed to use instead

keep the scanner at the top. kill the other 2. and then reuse the scanner from the top everywhere

so that ur whole program is using one scanner

not 3 or more

listen

ur still not reading what im saying

do u understand why u get an error?

if not, we have a much bigger problem now

no

what is the error message

and why is that the case

what does that mean

and why did it work before

no

or which one do u mean

okay. so u dont understand why its red now?

what does this line mean

int choice = scnr.nextInt();

what does it do

which one

yes. but why does it use this scanner and not the other two

what in this line is telling it to use that scanner

u have 3 scanners after all

yes. so what do u have to do to use the other scanner?

well. from the 3 scanners we have, which one do we want to use everywhere?

right. so what do u have to change for

int choice = scnr.nextInt();

to use that scanner instead

so u would write

int choice = nextInt();

instead, or what?

and then u think it uses the other scanner?

no

the scanner being at the very top is correct. u dont have to do anything anymore to use it

okay. lets approach it from this side:

Scanner a = new Scanner(System.in); // 1
Scanner b = new Scanner(System.in); // 2
Scanner c = new Scanner(System.in); // 3

String text = b.nextLine();

which scanner does the text thing use?

scanner 1, 2 or 3?

and what do u have to change so that it uses the third scanner instead?

correct. so back to our original problem. what do u have to change in

int choice = scnr.nextInt();

so it uses the scanner at the top of the program instead of the one in ur method?

so u would write

int choice = static scaner.nextInt();

or what exactly?

no

im not sure why u cant transfer it

look at this again

Scanner a = new Scanner(System.in); // 1
Scanner b = new Scanner(System.in); // 2
Scanner c = new Scanner(System.in); // 3

String text = b.nextLine();

for some reason u were able to tell me that it uses the second scanner

and that u have to change it into c.nextLine() to use the third scanner

so u understood this

now, u have to do the exact same in ur code

and someone ur totally lost

which makes little sense

cool. so now use input in both methods and get rid of the two scanners u created in the methods

so that everywhere in ur program ur only using the input scanner

alright. have a good one

we are here when u want to continue

🙂

no worries 🙂
