What will be the output of the program


import java.util.Formatter;

public class Formatting {
    public static void main(String[] args) {
        Formatter formatter = new Formatter();
        System.out.println(
            formatter.format("%b %b %b %b %b", 
                true, null, "false",  new Boolean("false"), 0)
        );
    }
}

true false true false true
true false false false false
true false true true false
true true false false true

Explanation

For "%b" if the argument is null, then the result is "false". If argument is a boolean or Boolean, then the result is the string returned by String.valueOf(). Otherwise, the result is "true".
