Question

can someone help me with this

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

WeatherStats.java

public class WeatherStats
{
public static void main(String[] args)
{
temperature t1 = new temperature(5);
t1.addNextTemp(50);
t1.addNextTemp(60);
t1.addNextTemp(80);
t1.addNextTemp(90);
t1.addNextTemp(80);
t1.addNextTemp(70);

System.out.println( "maximum change in temperature " + t1.getMaxDifference());
System.out.println("day number when maximum change in temperature occurred " + t1.getMaxDiffDay());
}
}

temperature.java

public class temperature
{
public double[] tempe ;
int entries;

public temperature(int n) {
this.tempe = new double[n];
this.entries = 0;
}
public temperature() {
this.tempe = new double[10];
this.entries = 0;
}

   public boolean addNextTemp(double t)
   {
       if(this.entries < this.tempe.length)
       {
           this.tempe[entries] = t;
           this.entries = this.entries + 1;
           return true;
       }
       else
       {
           System.out.println("No position available in collection");
           return false;
       }
   }

   public double getMaxDifference()
   {
       double maxdiff = 0;
       for (int i = 1; i<this.tempe.length ; i++ ) {
           if(java.lang.Math.abs(tempe[i] - tempe[i-1]) >= maxdiff)
           {
               maxdiff = java.lang.Math.abs(tempe[i] - tempe[i-1]);
           }          
       }
       return maxdiff;
   }

   public int getMaxDiffDay()
   {
       double maxdiff = 0;
       int index = 1;
       for (int i = 1; i<this.tempe.length ; i++ ) {
           if(java.lang.Math.abs(tempe[i] - tempe[i-1]) >= maxdiff)
           {
               maxdiff = java.lang.Math.abs(tempe[i] - tempe[i-1]);
               index = i;
           }          
       }
       return index + 1;
   }

}

Sample Output:

No position available in collection
maximum change in temperature 20.0
day number when maximum change in temperature occurred 3
