JAVA INTRO COURSE

You will have to write the following file for the PRSGame.java. There will be two private fields score: int p2choice: int

Constructor

You will to create a constructor that will use the setScore() to set the score to 0 and set the p2choice to a random number between 1 and 3.

setScore() There will be a setter called setScore(), it will return nothing, but take in int s. It will check to see if the int s passed to it is equal to or less than 0 and set score to zero, else it will set the score to s.

getScore() The getter getScore() will return the field score.

checkWinner() This method will take in a variable int c and compare that to p2choice.

First it will use a for loop to count to 3, then it will check the results. Use the scanner.nextLine to take in the pressing of enter.

Then compare the two player choices(hint: may be useful to use a switch) This will return a string that will let the player know if they won or lost. If they win, score increases by one, if they lose score decreases by one, if they tie, no change.

newChoice() This will be a public method that resets the computer player to a random choice from 1-3 in p2choice.

Explanation / Answer

Midterm2.java:

import java.util.Scanner;

public class Midterm2
{
public static void main(String[] args)
{
  int choice;
  Scanner input=new Scanner(System.in);
  PRSGame player2 =new PRSGame();
  int score=0;
  do{
   System.out.println("Score is:" + player2.getScore());
   menu();
   choice =input.nextInt();
   switch(choice){
   case 1:{
    System.out.println("You choose Rock, nice and solid!");
    System.out.println(player2.checkWinner(choice));
    score =player2.getScore();
    break;
   }
   case 2:{
    System.out.println("You choose Paper, must be feeling flat!");
    System.out.println(player2.checkWinner(choice));
    score =player2.getScore();
    break;
   }
   case 3:{
    System.out.println("You choose Siccors, how cutting edge!");
    System.out.println(player2.checkWinner(choice));
    score =player2.getScore();
    break;
   }
   case 0:{
    System.out.println("Thanks for playing");
    break;
   }
   default:{
    System.out.println("That is not a choice!");
    break;
   }
    }
   player2.newChoice();
  }while(choice!=0);
}
   public static void menu(){
    System.out.println("Please select a choice: 1-Rock 2-Paper 3-Sissors 0-End");
   }
}

PRSGame.java

public class PRSGame
{
int score;
int p2choice;

PRSGame()
{
  setScore(0);
  p2choice = (int) (Math.random() * 3 + 1);
}

public void setScore(int s) {
  if (s <= 0)
   score = 0;
  else
   score = s;

}

public int getScore() {
  return score;
}

public void print()
{
  if(p2choice ==1)
   System.out.println("Rock");
   if(p2choice ==2)
   System.out.println("Paper");
   if(p2choice ==3)
   System.out.println("Sissors");
}
public String checkWinner(int c) {

  print();
  if (p2choice == c) {
   
   return "Draw";
  }
  if (p2choice < c) {
   score++;   
   return "Win";
  }
  if (p2choice > c) {
   score--;   
   return "Lost";
  }

  return "";
}

public void newChoice() {
  p2choice = (int) (Math.random() * 3 + 1);
}

}
