Question

Java. May only use import java.util.*; and import java.io*; packages. Write a program called WeatherReporter that prompts the user for an input file name. reads the given file, which is in the format of CharlotteWeather2010.txt, line by line and uses the processLine() method as defined below:


public static void processLine (String line){
 

}


to output to the console the data for each day formatted as shown below:


01/01/2010 Low:  34.0 High:  48.0 Rain:  no Snow:  no
01/02/2010 Low:  24.1 High:  48.0 Rain:  no Snow:  no
