Methods • completeTask () • Abstract method that does not take in anything and does not return anything • (Note: any class that implements Crewmate must provide a method definition for this method) Player.java This class represents a player in the game. You must not be able to create an instance of this class (Hint: there is a keyword that prevents us from creating instances of a class). Players implement the Comparable interface with the proper type parameter. A portion of this class was given to you. There are 2 methods (as follows) that you need to implement. Make sure to code where there are comments that say YOUR CODE HERE. Javadocs have been provided to guide you. Variables (These have been provided to you) • String name - The Player's name as a String. • int susLevel - This represents how suspicious a Player is; the higher, the more suspicious. • boolean frozen - This represents if a Player is frozen, which will affect their ability to participate in some methods below. • static Player [] players - This is the array of Player objects that have been created. It is always guaranteed to be full by the constructor (no null spaces), so if a Player is created, players becomes larger by one. Frozen players will NOT be removed from this array! (Note: It's ok move around elements in this array, but don't add or delete any elements) Methods Do not create any other methods than those specified. Any extra methods will result in point deductions. All methods must have the proper visibility to be used where it is specified they are used. • emergency Meeting ( ) • Any concrete class that extends the Player class must provide a method definition for emergency Meeting() • An abstract method for a Player to call an emergency meeting to vote on which Player to freeze • Does not return anything • compareTo (Player p) • Override the compare To method (You should be able to put @Override on the line before the method header) • Takes in a Player object and returns an int, adhering to the API contract (Comparable Interface) • The method body should compare two Player objects based on the susLevel attribute. If the current Player instance's susLevel is less than the Player passed in, return a negative number. If it is greater, return a positive number. If their susLevel attributes are equal, return 0
RedAstronaut.java This file defines a RedAstronaut, which is a Player and should have all attributes of one. Have RedAstronaut implement the Impostor interface. Variables All variables must be not allowed to be directly modified outside the class in which they are declared, unless otherwise stated in the description of the variable. Hint: there is a specific visibility modifier that can do this! The Red class must have these variables. Do NOT re-declare any of the instance variables declared in Player class: • skill - a String that represents skill of the Red crewmate a String value of either inexperienced, experienced, or expert. Constructors • A constructor that takes in the name, susLevel, and skill and sets all fields accordingly. It must accept the variables in the specified order. Assume that the passed in parameter for skill will be one of the three values, although it may have different capitalization. • Hint: There is a specified keyword in L12 to access the superclass's constructor. • A constructor that takes in just a name and assigns the following default values: • susLevel: 15 skill: experienced Methods Do not create any other methods than those specified. Any extra methods will result in point deductions. All methods must have the proper visibility to be used where it is specified they are used. • emergencyMeeting ( ) • A Player that is frozen cannot call an emergency meeting. • Holds a meeting and votes out (freezes) the most suspicious Player, only considering Players that are not frozen • The player that has the highest susLevel (that is NOT the current impostor calling the meeting) will be accused of being the impostor and will be voted off • If two players have the same highest susLevel, no player will be voted off. • Hint: think of an easy way to do this without having to iterate through the entire array. Check the Java API for Arrays for a method you can use • Make sure to change the frozen variable of the player to true when voting off players (don't call the freeze method!) • At the end of the vote, check if the game is over using the provided method in Player.java • Does not return anything
freeze (Player p) • Implements the method provided in the Impostor interface. • It is not possible to freeze another Impostor, and an Impostor that is frozen cannot attempt to freeze. If the passed in Player is an Impostor, the method should end. Freezing an already frozen Player should also do nothing. • A freeze is successful if the RedAstronaut's susLevel is less than the Player's • If the freeze is unsuccessful, the RedAstronaut's susLevel doubles (multiply the current susLevel by 2) • Remember to change the frozen boolean value for the Crewmate as needed. • After the freeze attempt, check if the game is over using the provided method in Player.java • Does not return anything • sabotage (Player p) • It is not possible to sabotage another Impostor, and an Impostor that is frozen cannot sabotage. Also, sabotaging a frozen Player should do nothing. • If the Impostor's susLevel is under 20, through shifty maneuvers and cunning words, they are able to increase the Crewmate's susLevel by 50% • Otherwise, they can only manage to increase the Crewmate's susLevel by 25% • (Note: In both cases, the the Crewmate's susLevel is rounded down to the nearest int value) • Does not return anything • equals (Object o) • Two Red are equal if they both have the same name, frozen, susLevel, and skill . Returns a boolean .toString() - returns a String describing RedAstronaut as follows: (Note: replace the values in brackets [] with the actual value) • "My name is [name], and I have a suslevel of [susLevel]. I am currently (frozen / not frozen). I am an [skill] player!" • If susLevel is greater than 15, return the String in all capital letters. • You must use the toString() method from the Player class to receive full credit. . Getters and Setters as necessary. BlueAstronaut.java This file defines a BlueAstronaut, which is a Player and should have all attributes of one. Have BlueAstronaut implement the Crewmate interface. Variables All variables must be not allowed to be directly modified outside the class in which they are declared, unless otherwise stated in the description of the variable. Hint: there is a specific visibility modifier that can do this!
The Blue class must have these variables. Do NOT redeclare any instance variables created in the Player class • numTasks the number of tasks that needs to be completed as an integer number • taskSpeed - the speed at which the astronaut is completing each task as a positive, nonzero integer number Constructors • A constructor that takes in the name, susLevel, numTasks, and taskSpeed and sets all fields accordingly. It must accept the variables in the specified order. • A constructor that takes in just a name and assigns the following default values: susLevel: 15 numTasks: 6 • taskSpeed: 10 Methods Do not create any other methods than those specified. Any extra methods will result in point deductions. All methods must have the proper visibility to be used where it is specified they are used. • emergencyMeeting ( ) • A Player that is frozen cannot call an emergency meeting. • Holds a meeting and votes out (freezes) the most suspicious individual of the Player objects, only considering Players that are not frozen • The player that has the highest susLevel will be accused of being the impostor and will be voted off (This could be them!) • If two players have the same highest susLevel, no player will be voted off. • Hint: think of an easy way to do this without having to iterate through the entire array. Check the Java API for Arrays for a method you can use. • Make sure to change the frozen variable of the player to true when voting off players (don't call freeze!) • At the end of the vote, check if the game is over using the provided method in Player.java • Does not return anything completeTask () • A BlueAstronaut that is frozen cannot complete tasks. • If taskSpeed is greater than 20, subtract 2 from numTasks. Otherwise, subtract 1 from numTasks. • If numTasks falls below 0, set it to 0 • After BlueAstronaut is done with their tasks, meaning numTasks is equal to 0 (only for the first time), • Print out "I have completed all my tasks" • Then reduce BlueAstronaut's susLevel by 50% (round down)
• Does not return anything. • equals (Object o) • Two BlueAstronauts are equal if they both have the same name, frozen, susLevel, numTasks, and taskSpeed • Returns a boolean .toString() returns a String describing BlueAstronaut as follows: . "My name is [name], and I have a suslevel of [susLevel]. I am currently (frozen / not frozen). I have [numTasks] left over." • If susLevel is greater than 15, return the String in all capital letters. . (Note: replace the values in brackets [] with the actual value) • You must use the toString() method from the Player class to receive full credit. . Getters and Setters as necessary. Gameplay.java This Java file is a driver, meaning it will run the simulation. You can also use it to test your code. Here are some basic tests to get you started with Amidst Us. These tests are my no means comprehensive, so be sure to create your own! This is just to show an example of object implementation to see how objects interact with each other. Feel free to play around with different values and method callings, especially using toString to check the values after every step! This will NOT be turned in. Create a BlueAstronaut with the following fields: name = "Bob", susLevel = 20, numTasks = 6, taskSpeed = 30 Create a BlueAstronaut with the following fields: name = "Heath", susLevel = 30, numTasks = 3, taskSpeed = 21 Create a BlueAstronaut with the following fields: ● .name = "Albert", susLevel = 44, numTasks = 2, taskSpeed = 0 Create a BlueAstronaut with the following fields: name = "Angel", susLevel = 0, numTasks = 1, taskSpeed = 0 Create a RedAstronaut with the following fields: name = "Liam", susLevel = 19, skill = "experienced" Create a RedAstronaut with the following fields:
Create a RedAstronaut with the following fields: name = "Liam", susLevel = 19, skill = "experienced" Create a RedAstronaut with the following fields: ● • name = "Suspicious Person", susLevel = 100, skill = "expert" Have the objects do the following: 1. Have RedAstronaut Liam sabotage BlueAstronaut Bob. After the sabotage: • Bob should have: susLevel = 30, frozen = false 2. Have RedAstronaut Liam freeze RedAstronaut Suspicious Person: Nothing should happen 3. Have RedAstronaut Liam freeze BlueAstronaut Albert. After the freeze: • Liam should have: susLevel = 19 • Albert is now frozen 4. Have BlueAstronaut Albert call an emergency meeting: • Nothing should happen since he is frozen 5. Have RedAstronaut Suspicious Person call an emergency meeting: • This will result in a tie between Bob and Heath, so nothing should happen 6. Have BlueAstronaut Bob call an emergency meeting: Suspicious Person should have: frozen = true 7. Have BlueAstronaut Heath complete tasks: • Heath should have: numTasks = 1 8. Have BlueAstronaut Heath complete tasks: "I have completed all my tasks" should be printed to console • Heath should have: numTasks = 0, susLevel = 15 9. Have BlueAstronaut Heath complete tasks: • Nothing should happen 10. Have Red Astronaut Liam freeze Angel: • ● Angel should have: frozen = false • Liam should have: susLevel = 38 11. Have RedAstronaut Liam sabotage Bob twice:
• Bob should have: susLevel = 46 (30→ 37 → 46) 12. Have Red Astronaut Liam freeze Bob: Bob should have: frozen = true Now there are two options going forward 13. Have BlueAstronaut Angel call emergency meeting: Liam should have: frozen = true "Crewmates win!" should be printed to console Or 14. Have RedAstronaut Liam call sabotage on Heath 5 times: • Heath should have: susLevel = 41 (15-18-22-27-33-41) 15. Have RedAstronaut Liam freeze Heath: • Heath should have: frozen = true • "Impostors win!" should be printed to console Reuse your code when possible. Certain methods can be reused using certain keywords. Allowed Imports To prevent trivialization of the assignment, you are only allowed to import java.util.Arrays. You are not allowed to import any other classes or packages. Feature Restrictions There are a few features and methods in Java that overly simplify the concepts we are trying to teach or break our auto grader. For that reason, do not use any of the following in your final submission: • var (the reserved keyword) • System.exit
