How would I log each element in the hours array we just created?

We used the debugger here to see if the array was being populated correctly, but is there an easy way to log all the values in an array of objects?

Log.d(TAG, Arrays.toString(forecast.getHourlyForecast()));

If I use Arrays.toString I see something like this [com.example.stormy.weather.Hour@2fd2ba76, com.example.stormy.weather.Hour@3ecd8877, etc, etc, etc] so I can tell that all the objects are being created but I can't figure out how to display the actual information each object contains.

In the Hour class, override the toString method.

    @Override
    public String toString() {
        return "{ time: " + time
                + ", summary: " + summary
                + ", temperature: " + temperature
                + ", icon: " + icon
                + ", timezone:" + timezone
                + "}";
    }

By default, the string representation of the object is the name of the object's class, the character @, and the object's hash code. By overriding the toString method, you can specify a different string to use to represent the object.
