Scanner and nextChar() in Java

Scanner class in Java supports nextInt(), nextLong(), nextDouble() etc. But there is no nextChar() (See this for examples)

To read a char, we use next().charAt(0). next() function returns the next token/word in the input as a string and charAt(0) function returns the first character in that string.

// Java program to read character using Scanner
// class
import java.util.Scanner;
public class ScannerDemo1
{
public static void main(String[] args)
{
// Declare the object and initialize with
// predefined standard input object
Scanner sc = new Scanner(System.in);

// Character input
char c = sc.next().charAt(0);

// Print the read value
System.out.println("c = "+c);
}
}
Input :

g
Output :

c = g
