4.5 Static and toString — object counter

Total: 0 / 4 pts

Practice mode — check each part and get hints as you go.

Task

Add to Widget a static field count and a constructor that increases it by one every time a widget is built.

A static field belongs to the class, not to any single object — all widgets share one counter. The program builds three widgets and prints 3.

Your solution

class Widget {
    // Add a static field count that tracks how many Widgets exist,
    // and a constructor that increases it by 1 each time.

}

public class Main {

    public static void main(String[] args) {
        new Widget();
        new Widget();
        new Widget();
        System.out.println(Widget.count);
    }
}
