Question

Years of research have revealed the spec class that implements this unique movem random point (with integer coordinates x and y). When it decid coordinates by the followin example, if x is 37 and y is 12 ial mechanism behind Tigger's bouncy step. Design a Tigger ent, which I will describe below. A Tigger always starts in a es to bounce, a Tigger changes its x and y g rule: x becomes the sum of the squares of its digits, and so does y. For they turn into 58 (32+72) and 5 (1'+22) respectively. In your main method create such an object and make it bounce a few times, for example: java One Tigger just bounced to (162, 105) Tigger just bounced to 41, 26) Tigger just bounced to 17, 4o) Tigger just bounced to 50, 16) Tigger just bounced to 25, 37) Tigger just bounced to ( 29, 58) Tigger just bounced to 85, 89) Tigger just bounced to 89, 145) Tigger just bounced to (145, 42) Tigger just bounced to 42, 20) Tigger just bounced to (20, 4) Tigger just bounced to 4, 16) Tigger just bounced to (16, 37) Tigger just bounced to (37, 58) Tigger just bounced to (58, 89)
Solve the problem in Java

Answer 1

Here is the code for TiggerBounce.java:

import java.util.*;
class TiggerBounce
{
    int x;
    int y;
    public TiggerBounce()   //Default constructor, which initializes x, and y with random values.
    {
       Random randGen = new Random();
       x = randGen.nextInt();
       y = randGen.nextInt();
    }
    public TiggerBounce(int x, int y)   //Parameterized constructor, which initializes x, and y with given values.
    {
       this.x = x;
       this.y = y;
    }
    private int sumOfSquaresOfDigits(int value)   //Private function to compute the sum of digits in a number.
    {
       int sum = 0;
       while(value != 0)
       {
          int rem = value % 10;
          sum += rem * rem;
          value /= 10;
       }
       return sum;
    }
    public void computeNextBounce()   //Computes the next point.
    {
       x = sumOfSquaresOfDigits(x);
       y = sumOfSquaresOfDigits(y);
    }
    public int getX() { return x; }   //Getter for x.
    public int getY() { return y; }   //Getter for y.
    public String toString()       //toString() method.
    {
       return "(" + x + ", " + y + ")";
    }
      
}

And the code for TiggerBounceDemo.java is:

class TiggerBounceDemo
{
    public static void main(String[] args)
    {
       TiggerBounce myBounce = new TiggerBounce(162, 105);
       for(int i = 0; i < 15; i++)
       {
          System.out.println("Tigger just bounced to " + myBounce);
          myBounce.computeNextBounce();
       }
    }
}

And the output screenshot is:
