Return a String value when boolean is true

Question

I'm making some assignments and I've stumbled upon something I can't seem to fix.

So I made an enum class containing all the days of the week, and gave them a corresponding parameter to output the String value of the enums inside.

public enum Day{ Monday("monday");}

I then made the String to my enums final and made a constructor for it.

private final String day;

Day (String aDay) { this.day = aDay; }

Now I had to make a method that checks if it's a weekday or if it's a day in the weekend. I had to use a boolean for this.

    private boolean isWeekday() {
    if (this.getDay().equals("saturday") || this.getDay().equals("sunday")) {
        return false;
    } else {
        return true;
    }
}

Now this part is where I'm struggling right now. I had to make a toString method that returns the day and if it's a weekday or not.

The output should be like this:

monday(weekday) or sunday(weekend)

My method "isWeekday" will obviously only return true's or false's at this point. How can I let it print out weekday when it's true and weekend when it's false?

    public String toString() {
    return String.format("%s(%s)", this.getDay(), ??;
}

Thanks in advance, I've tried searching Google but I haven't had any succes.

Use the ternary operator.

You can use the ternary operator (also called conditional operator):

public String toString() {
    return String.format("%s(%s)", this.getDay(), isWeekDay() ? "(weekday)" : "(weekend)");
}

Relevant part:

isWeekDay() ? "(weekday)" : "(weekend)"

This basically results in

if(isWeekDay()) { 
    return "(weekday)";
} else {
    return "(weekend)";
}
