What will be the result of the following code execution?


public class Main {
    public static void main(String[] args) {
        byte b = 12;
        byte k = b + 1;
        System.out.println(k);
    }
}

12
13
The code will not compile
null

Explanation

When performing arithmetic operations with values of type byte, char, short they are implicitly converted into the type int. Therefore, the result of the expression b + 1 will also be of type int. For it to be able to be assigned to a variable k, you need to use explicit type conversion:

byte k = (byte)(b + 1);
