What does the program print?

JAVA

public class Main {
    public static void main(String[] args) {
        System.out.println('a' + 'b');
    }
}

195

Expecting ab: + glues only when one side is a String; two char values become int, and their codes 97 and 98 are added.
Expecting a compile error: char is a 16-bit number type, so arithmetic on it is legal and gives an int.
