Your just need to add the humidity field to the CurrentWeather Class...

private double humidity;

then use Android studio to create your Getter and Setter for it by

1 - Placing your caret at anywhere on the field "humidity"

2 - Use the light bulb to select "Create Getter and Setter for humidity" option.

It will generate these methods for the field...

 public double getHumidity() {
    return humidity;
}

public void setHumidity(double humidity) {
    this.humidity = humidity;
}
