[java] How to take character input in java

In C, we are able to take input as character with the keyword char from keyboard as

scanf("%c", &ch);

But In Java how to do this?

I have tried this:

import java.util.Scanner;

public class Main {
  public static void main(String[] args) {
    Scanner scanner = new Scanner(System.in);
    System.out.println("Enter a character: ");
    char c = scanner.next().charAt(0);
    System.out.println("You have entered: "+c);
  }
}

use :

char ch=**scanner.nextChar**()

You can simply use (char) System.in.read(); casting to char is necessary to convert int to char

import java.util.Scanner;

class CheckVowel {

    public static void main(String args[]) {   
        Scanner obj= new Scanner(System.in);

        char a=obj.next().charAt(0);

        switch(a) {    
            case 'a':  //cases can be used together for the same statement
            case 'e':
            case 'i':
            case 'o':
            case 'u':
            case 'A':
            case 'E':
            case 'I':     
            case 'O':
            case 'U':
                     {
                System.out.println("Vowel....");   
                break;
               }    
            default:    
                System.out.println("Consonants....");
        }
    }
}

you can use a Scanner to read from input :

Scanner scanner = new Scanner(System.in); 
char c = scanner.next().charAt(0); //charAt() method returns the character at the specified index in a string. The index of the first character is 0, the second character is 1, and so on.

Here is the sample program.

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class ReadFromConsole {

  public static void main(String[] args) {

    System.out.println("Enter here : ");

    try{
        BufferedReader bufferRead = new BufferedReader(new InputStreamReader(System.in));

        String value = bufferRead.readLine();

        System.out.println(value);
    }
    catch(IOException e)
    {
        e.printStackTrace();
    }
  }
}

You can get it easily when you search in Internet. StackExchange recommends to do some research and put some effort before reaching it.

import java.util.Scanner;

class SwiCas {

    public static void main(String as[]) {   
        Scanner s= new Scanner(System.in);

        char a=s.next().charAt(0);//this line shows how to take character input in java

        switch(a) {    
            case 'a':
                System.out.println("Vowel....");   
                break;    
            case 'e':
                System.out.println("Vowel....");   
                break;   
            case 'i':
                System.out.println("Vowel....");   
                break;
            case 'o':
                System.out.println("Vowel....");    
                break;    
            case 'u':
                System.out.println("Vowel....");   
                break;    
            case 'A':
                System.out.println("Vowel....");    
                break;    
            case 'E':
                System.out.println("Vowel....");  
                break;    
            case 'I':
                System.out.println("Vowel....");    
                break;    
            case 'O':
                System.out.println("Vowel....");    
                break;   
            case 'U':
                System.out.println("Vowel....");    
                break;    
            default:    
                System.out.println("Consonants....");
        }
    }
}

I had the same struggle and I this is what I used:

} public static void main(String[] args) {

Scanner scan = new Scanner(System.in);
System.out.print("Please enter the string: ");
String input = scan.next();
System.out.print("Please enter the required symbol: ");
String symbol = scan.next();        
char symbolChar = symbol.charAt(0);

This works just fine. The idea is to get from the string the only char in it.

using java you can do this:

Using the Scanner:

Scanner reader = new Scanner(System.in);
String line = reader.nextLine();
// now you can use some converter to change the String value to the value you need.
// for example Long.parseLong(line) or Integer.parseInt(line) or other type cast

Using the BufferedReader:

BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
String line = reader.readLine();
// now you can use some converter to change the String value to the value you need.
// for example Long.parseLong(line) or Integer.parseInt(line) or other type cast

In the two cases you need to pass you Default input, in my case System.in
