Question

In Java please, !

8. Write your own class called WeatherStats to manage the ordered collection

of high temperatures. Have two constructors, one for a default maximum size

collection of 10, and the second for a user argument defined maximum size

collection. The user class will not do any prompting to the user or reading

of data, instead create the following methods:

• boolean addNextTemp (double temp) – add the temp to the next available

position in the collection, if room allows.

• getMaxDifference() – returns the maximum change in temperature (in

absolute value) on two consecutive days.

• getMaxDiffDay() – returns the day number for the second day of the two

consecutive days that the maximum change in temperature (in absolute value)

occurred.

Explanation / Answer

Here is the class for you:

class WeatherStats
{
    double[] highTemperatures;
    int capacity;
    int currentSize;
    //Have two constructors, one for a default maximum size collection of 10,
    //and the second for a user argument defined maximum size collection.
    WeatherStats()
    {
       capacity = 10;
       highTemperatures = new double[capacity];
       currentSize = 0;
    }
   
    WeatherStats(int size)
    {
       capacity = size;
       highTemperatures = new double[capacity];
       currentSize = 0;
    }
   
    //boolean addNextTemp (double temp) – add the temp to the next available
    //position in the collection, if room allows.
    boolean addNextTemp(double temp)
    {
       if(currentSize < capacity)
       {
          highTemperatures[currentSize++] = temp;  
          return true;
       }
       return false;   
    }
    //getMaxDifference() – returns the maximum change in temperature (in
    //absolute value) on two consecutive days.
    double getMaxDifference()
    {
       double maxDiff = Math.abs(highTemperatures[0] - highTemperatures[1]);
       for(int i = 1; i < currentSize-1; i++)
           if(Math.abs(highTemperatures[0] - highTemperatures[1]) > maxDiff)
               maxDiff = Math.abs(highTemperatures[i] - highTemperatures[i+1]);
       return maxDiff;      
    }
    //getMaxDiffDay() – returns the day number for the second day of the two consecutive
    //days that the maximum change in temperature (in absolute value) occurred.
    int getMaxDiffDay()
    {
       int maxDiffDay = 1;
       double maxDiff = getMaxDifference();
       for(int i = 0; i < currentSize-1; i++)
           if(Math.abs(highTemperatures[i] - highTemperatures[i+1]) == maxDiff)
               return i+1;
       return 0;      
    }
}
