Casting from a char to int

Question

Never work this code no matter what I use
It does not work
import java.util.Scanner;
class Main {
public static void main(String[] args) {
Scanner read = new Scanner(System.in);
char a = read.next().charAt(0);
// int c= Integer.toString(a).charAt(0);
// int c = Integer.parseInt(a);
// int c = (int) a.charAt(0);
// int c = (char) (a+1);
// int c = Character.getNumericValue(a);
int c = Integer.parseInt(String.valueOf(a));
//int c = a;
// a = (c);
int c = (int) a.charValue()
System.out.println(c);
//your code goes here
}

Answer 1

char a = '3';
char b = '4';
int c = Character.getNumericValue(a);
int d = Character.getNumericValue(b);
int r = c + d;
System.out.println(r);

Answer 2

In Java, we can convert the Char to Int using different approaches. If we direct assign char variable to int, it will return the ASCII value of a given character. https://www.pfmlogin.org/
If the char variable contains an int value, we can get the int value by calling Character. getNumericValue(char) method.
