weatherextension.java

目前在JAVA下编程时对XML的操作很重要

package com.extension;


public interface weatherExtension {

        /**
         * Converts "Temperature" element's value in Celsius, then returns it.
         */
        float getTemperatureInCelsius();

        /**
         * Converts "Visibility" element's value in Metric units i.e. Kilometers, then returns it.
         */
        float getVisibilityInKilometers();


}
