Question

The syntax to input a character through scanner class.
Syntax: char = .nextLine();
Syntax: char = .next().charAt(0);
Syntax: char = .charAt(0);
Syntax: char = .next().charAt(1);​

Answer 1

Explanation:

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
