Scanner has no definition of method getChar.

Scanner has no definition of method getChar.
so how can i make a program that reads the 1st character that the user enters:

for example:

if user enters :: A 1 2

ch= console.nextChar();
g = console.nextInt();
h= console.nextInt();

what can i use instead of nextChar()??
Thanks in advance

You can use scanner.next() it returns string, but you can convert it to char.

just read it as String, convert it to an array of chars, or make a new Scanner class in which you define a nextChar() method

Re: console.nextChar(); ???

mmm.... just in case you need this again, a better way to do it is:

variable = console.next().charAt(0);

I hope it helps...

@hifazat
hiiii 'buddyyyy ...
if a thread is solved, it means he did succees in getting the caracter.
don't revive threads that haven't been active for over two years, don't revive threads that are marked 'solved' and try to use some proper language.
English is chosen here, since most developers are familiar with it, but then try to keep it with correct grammar and vocabulary, since we don't all have english as our first language.

The company I work for has 6k developers in America/Europe and 12k developers in India. I would agree that most developers certainly are familiar with English, but from my experience it is broken, heavily-accented English...haha
