## Description

Background
There is a “pay to play” cell phone game in which users utilize augmented reality to
capture various monsters, called “Brokemon­Go”. In the game, players pay to capture
various monsters that are in their environment. If a monster is captured, the player
receives money. If the monster is not captured, the player loses their money. The game
application tells the player the monster’s location (in x, y coordinates), its time of
appearance (Ta
) and the duration of its existence (Te
). This means that the monster will
appear at time Ta
and will exist from time Ta
to Ta + Te
. The objective of the game is
for the user to get to the location of the monster that it is trying to capture, before the
monster disappears.
playing the game because the monster disappears right before they are able to make it to
the monster’s location. Your friend just found out that you are learning how to program
and has asked you to help them develop some code to help them play the game better,
and not lose any more of their money. Your friend would like you to help them decide or
select if it would be wise to pursue a given monster. Please see the specific rules in the
Section “Probability of Capture”.
found out that they have created a new rule. The rule is: If a player’s playerID ends in 00
to 49, this person is on the “lucky list”; however if the playID ends in 50 to 99, this
person is on the “normal list”. People on the lucky list are given special privileges, which
are outlined in the “Probability of Capture” section.
Create a piece of code that takes in the monster’s location, the monster’s appear time,
the monster’s exist time, the player’s ID, and the player’s location, the player’s walking
speed, and the player’s notice time. After this is done, your program should output the
player’s likelihood of capturing the monster. The pieces of data that will be supplied at
the console are:
· Monster Location: supplied as grid locations (x, y) (1 <= x <= 10, and 1 <= y <= 10) where x is the longitude and y is the latitude (see grid below, scale in km) · · Monster Appear Time: 1 to 1440 minutes (24 hours * 60 minutes in a day) · Monster possible Exist Time: 10 to 59 minutes · Player ID: exactly 8 digits, none beginning with a zero (integer) · Player Location: supplied as grid locations (x, y) where x is the longitude and y is the latitude · Player Notice Time: the time when player notices the monster appear on his/her cellphone app, on the same day as the monster appear. (1 to 1440). · Walk speed: the player's speed to get to the monster’s location. (10 to 200 m/minute). Probability of Capture You will use the following rules to decide the possibility of a player capturing the monster, based on the time the player get there. If the time the player gets to the monster’s location (Tg ) is less than or equal to the sum of the monster appear time (Ta ) and the possible exist time (Te ), Tg <= Ta + Te, the player will definitely capture the monster. If the player arrives late, i.e., Tg > Ta + Te, the monster’s disappear probability increases with the proportion
((Tg ­ (Ta + Te))/ Te) * 100. The likelihood of capturing the monster is
defined by the thresholds below.
Definitely
· The time the player gets there (Tg
) is less than or equal to the sum of the
monster’s appear time (Ta
) and the possible exist time (Te
), i.e., Tg <= Ta+Te Highly Likely · Tg > Ta + Te
· Lucky List: (Tg ­ (Ta + Te)) / Te is within 0 to 10%
(inclusive)
· Normal List: (Tg ­ (Ta + Te)) / Te is within 0 to 5%
(inclusive)
Likely
· Tg > Ta + Te
· Lucky List: (Tg ­ (Ta + Te)) / Te is greater than 10%, but
within 30% (inclusive)
· Normal List:(Tg ­ (Ta + Te)) / Te is greater than 5%, but
within 20% (inclusive)
Unsure
· Tg > Ta + Te
· Lucky List: (Tg ­ (Ta + Te)) / Te is greater than 30%, but
within 40% (inclusive)
· Normal List: (Tg ­ (Ta + Te)) / Te is greater than 20%, but
within 35% (inclusive)
Unlikely
· Tg > Ta + Te
· Lucky List: (Tg ­ (Ta + Te)) / Te is greater than 40%, but
within 50% (inclusive)
· Normal List: (Tg ­ (Ta + Te)) / Te is greater than 35%, but
within 40% (inclusive)
Highly Unlikely
· Tg > Ta + Te
· Lucky List: (Tg ­ (Ta + Te)) / Te is greater than 50%
· Normal List: (Tg ­ (Ta + Te)) / Te is greater than 40%
Code Structure
1. Read in the information about the monster from the console (all integers)
· Monster Location, Appear Time and Possible Exist Time
2. Read in the information about the player from the console (all integers)
· Player ID
· Player Walk Speed
· Player Find Time and Location
3. Determine the player’s state
· What type of player he/she is (“lucky list” vs. “normal list”)
· When the player will arrive at the monster location
· Whether he/she is late or not; if they are late, what percentage it is
4. Output the possibility the player capturing the monster (definitely, highly likely,
likely, unsure, unlikely, highly unlikely). The possibility word(s) should come
directly before the word “possibility”, regardless of the grammar

Notes
● You may assume that we will only give reasonable input, within the range and
bounds of the description and of the correct type (integer).
● “Within” means “up to and including”. For example, if the possibility is within
5%, this means possibility <= 5%. ● Please use System.out.println("...."); to print your output in lieu of System.out.print("...."); ● Please use the Math library to support your calculations. You can import it by adding this line to the top of your code: ○ import java.lang.Math; ● The straight line distance (d) is also known as the Euclidean distance and can be calculated using the formula below. ● Note that, since the map is in km scale, you should change it to m (that is, multiply by 1000) when you using d to calculate the time the player spend on the road. ● To get the absolute value, you can use Math.abs(). Abs works as follows: ○ int a = ­1; ○ a = Math.abs(a); //now a=1 ● · The exact time the player will arrive (Tg ) is calculated using the formula below. Tg = Tn + (d / S) ● Where Tn denotes the time when the player notices the monster, and S denotes the player’s walking speed. Note that, if d and S are both integer types, you should convert at least one to a double type to get the most accurate result. ● The distance and the time the player will arrive must be rounded off to include one digit after the decimal. This can be achieved using Math.round(). Please place the following line of code at the beginning of your program (before the Class header) to import the Math library’s functionality: ■ import java.lang.Math; ○ The following example demonstrates how you would use the Math library to round to one decimal place: ■ double num = 1.34567; ■ double roundedNum = Math.round(num*10)/10.0; Submission Requirements ● Name the project “Project1” ● Name the class “CaptureCalculator” ● Zip the java file (right click the java file > Send to > Compressed (zipped)
