Answer 1

your positioning of parenthesis

Answer 2

You're not reading user input correctly.

Answer 3

If you're meaning to use the scanner class you need to import it and call the method under the class

Answer 4

this line -> maxnumber = In.getInt();

Answer 5

see https://www.w3schools.com/java/java_user_input.asp

Answer 6

I have no clue what code you are trying to run this in, but I pasted the code into GDB and it will display your errors at the bottom

Answer 7

The language is java and you're trying to run c code @0mega

Answer 8

my teacher told me that dont use scanner

Answer 9

alright then these are your errors

Answer 10

what did your teacher tell you to use?

Answer 11

in.getInt();

Answer 12

sheesh no need to be rude

Answer 13

but my teacher told me not to use it

Answer 14

Did your teacher provide you a method to handle user input? You can't just call a function and expect it to work without importing it.

If you know the name of the function and the package it's supposed to come from I can tell you what the correct syntax is.

Answer 15

There's one more option. Maybe your teacher wants you to use Console.readline() and parse the string as an int? See something like https://www.tutorialspoint.com/java/io/console_readline.htm .

You should clarify if you can with your teacher. There aren't that many ways to read user input in java, (or any command line program to be honest. They all use standard system i/o streams after all.)

Answer 16

I believe you have to make a scanner

Answer 17

but my teacher told me not to use scanner
don't know why

Answer 18

How else would you get user input without a scanner?

Answer 19

Also in isn't declared..

Answer 20

In.getint?

Answer 21

I gave the asker 2 other ways to get user input without scanner.

Answer 22

Seems like you're trying to use a scanner.

Answer 23

Seems like you either have to declare variables or use a scanner.

Answer 24

Not sure how you could get input without a scanner... to scan the line of the input

Answer 25

Pretty sure declaring a scanner would be "Scanner scan = new Scanner();

Answer 26

Then you'd use scan.nextInt();

Answer 27

I believe.

Answer 28

Haven't coding in awhile forgot the syntax.
