Answer 1

All the explanation is provided in the comments of the code itself.

CODE--

public class CompareGeneric
{
   public static Comparable find_Largest(Comparable arr[])
   {
       //declare and initialize a variable to store the largest value
       Comparable largest=arr[0];
       //iterate over the array and find the largest
       for(int i=1;i<arr.length;i++)
       {
           if(arr[i].compareTo(largest)>0)
           {
               largest=arr[i];
           }
       }
       //finally return largest
       return largest;
   }
   public static void main(String[] args)
   {
       Double[] d= {2.0,5.7,22.4};
       System.out.println("Largest Double: "+find_Largest(d));
       Integer[] i= {1,2,3,4,5,6,7,8,9};
       System.out.println("Largest Integer: "+find_Largest(i));
   }
}
