Write a JAVA or C++ program that prompts the user for three numbers, then prints

• The sum
• The average
• The median (the middle number of the three)
• The maximum (the larger of the three)

You are required to implement a class

public class Trio
{
  /**
     Constructs a trio.
     @param aFirst the first value of the trio
     @param aSecond the second value of the trio
     @param aThird the third value of the trio
  */
  public Trio(int aFirst, int aSecond, int aThird)
  {
     ...
  }
  /**
     Computes the sum of the valies of this trio.
     @return the sum of the first, second and third values
  */
  public double getSum()
  {
     ...
  }
  ...
}

Then implement s class TrioTester that constructs a Trio object,
invokes its methods, and prints the results.
