Take a char input from the Scanner

Question

I am trying to find a way to take a char input from the keyboard.

I tried using:

Scanner reader = new Scanner(System.in);
char c = reade         


        

Answer 1

You should use your custom input reader for faster results instead of extracting first character from reading String. Link for Custom ScanReader and explanation: https://gist.github.com/nik1010/5a90fa43399c539bb817069a14c3c5a8

Code for scanning Char :

BufferedInputStream br=new BufferedInputStream(System.in);
char a= (char)br.read();

Answer 2

// Use a BufferedReader to read characters from the console.
import java.io.*;
class BRRead {
public static void main(String args[]) throws IOException
{
char c;
BufferedReader br = new
BufferedReader(new InputStreamReader(System.in));
System.out.println("Enter characters, 'q' to quit.");
// read characters
do {
c = (char) br.read();
System.out.println(c);
} while(c != 'q');
}
}

Answer 3

import java.io.*;

class abc // enter class name (here abc is class name)
{
    public static void main(String arg[])
    throws IOException // can also use Exception
    {
        BufferedReader z =
            new BufferedReader(new InputStreamReader(System.in));

        char ch = (char) z.read();
    } // PSVM
} // class

Answer 4

Try this

Scanner scanner=new Scanner(System.in);
String s=scanner.next();
char c=s.charAt(0);
