What will be the output of the following code?


public class Test {
    int i = 10;
    public int hashCode() {
        return i;
    }
    public static void main(String ... a) {
        System.out.println(String.format(" %1$b  ", new Boolean("fAlSe")) );
        System.out.println(String.format(" %1$H %2$s", new Test(), null ) );
    }
}

true
A null
false
B ""
false
A null
false
10 null
false
Test@a null

Explanation

Constructor Boolean(String) will always return false except when argument equals "true" ignoring case.
%1$H - will call (new Test()).hashCode() and show the result as hexadecimal string.
