How to get a single character as user input?

Answer 1

In Java and if a String fits you, you could perhaps do it like that:

Scanner sc = new Scanner (System.in);
String input = sc.nextLine();
String charac = input.substring(0,1);

If there are no mistakes, no matter how many characters the user inputs, it keeps only the first one.

Answer 2

In Java you may not be able to receive single characters with Scanner.

But you can get strings and convert them to char arrays with the toCharArray method:
string.toChatArray()
"Hello world!".toCharArray() == {'H', 'e', 'l', 'l', 'o', ' ', 'w', 'o', 'r', 'l', 'd', '!'}

Answer 3

This could work:

Scanner input = new Scanner (System.in);
char c = input.next ();

next() takes not the whole line.

Answer 4

Answer 5

Java:

import java.util.Scanner;

Scanner input = new Scanner (System.in);
int number = input.nextInt ();
String text = input.nextLine ();
double --> nextDouble()
long --> nextLong ();
