Question

Write a java program that simulates the operation of a Halloween Vampire Hunt game. In the game scenario, you are a vampire hunting a victim in a dark cave. The cave consists of 10 by 10 little squares, numbered 0-9 on each side; your victim is in the cave, with x-coordinate and y-coordinate 0-9 (both integers). On each turn, you guess where your victim is, and try to bite her/him. Your “health” is determined by the number of bloodpoints you have. At the beginning, your bloodpoints are initialized to a random integer, evenly distributed from 5 to 10, inclusive.

Unfortunately, there are also vampire hunters in the cave, shooting arrows at you. (The arrows are wood, of course, for killing vampires.) On each turn, generate a random integer from 0 to 2, inclusive.

If the random integer is 0, an arrow misses you; no damage is done
If the random integer is 1, an arrow grazes you; you lose one bloodpoint If the random integer is 2, an arrow hits you; you lose two bloodpoints

The game ends when 1) you guess where your victim is and bite her/him, or 2) you are shot by too many arrows, and your bloodpoints drop to zero or below.

Your program performs these operations:

1) generate random x and y coordinates for the victim (both integers, 0-9) (use the myRand() method, described below)

2) ask if the user would like to cheat
3) if the user is cheating, print the location of the victim
4) generate initial random bloodpoints for the vampire (5 to 10, an integer)

(use the myRand() method, again)
5) prompt the user to enter x and y coordinates (guess where victim is) 6) display the distance between the vampire and victim

(use the findDistance() method, described below)

7) check whether an arrow hits/misses the vampire; update bloodpoints (use the myRand() method again)

repeat (5) – (7) until the vampire guesses the correct location of the victim, or the vampire’s bloodpoints drop to zero or below

To break the project down into smaller, more manageable parts, first write the main program with some dummy methods for myRand() and findDistance(); the dummy methods just return the first argument; i.e.,

double findDistance(int x1, int y1, int x2, int y2)
{

return x1; }

int myRand(int low, int high)
{

return low; }

Then fill in the dummy methods.
