Java随机数猜测游戏商店的最低尝试次数

Question

我基本上已经完成了所有工作，只是我不知道如何使该程序记录每个会话的最佳成绩，而且我也不知道如何使该程序将播放器的信息每次都保存到.txt文件中。会话”结束。 .txt文件的格式应为用户名，运行次数，成功运行次数和最佳成绩。 到目前为止，我的代码是

        import java.util.Random;
import java.util.Scanner;
import java.util.Writer;
import java.util.File; 

public class GuessingGame3 {

    public static void main(String[] args)
    {

        Random generator = new Random(); //This is were the computer selects the Target

        int guess;
        int count = 0;
        int Target;
        String userName;
        String playagain;
        boolean play = true;
        int session = 0;
        int sessions = 0;

        Scanner consoleIn = new Scanner(System.in); 
        Scanner name = new Scanner(System.in); 

        System.out.println("Hello! Please enter your name:\n"); //This is were the user enters his/her name
        userName= name.nextLine();

        System.out.println("Hello "+ userName + " :) Welcome to the game!\n");


        while (play = true)
        {
            session++;
            Target = generator.nextInt(100) + 1;
            System.out.println("Can you guess the number i'm thinking off? You will have 6 attempts to guess the correct number"); //This is where the computer asks the user to guess the number and how many guesses they will have

            do {
                guess = consoleIn.nextInt();
                count++;

                if (guess > Target)
                System.out.println("Sorry! Your guess was too high! Guess again :)"); //This is to help the player get to the answer 
                else 
                if (guess < Target)
                System.out.println("Sorry! Your guess was too low! Guess again :)"); //This is to help the player get to the answer 
               }        
                while(guess != Target && count <6);

                if(guess == Target) {
                System.out.println("Congratulations "+  userName + ", it took you "+ count +" attempts to guess correctly!"); //This tells the player that they got the correct answer and how many attempts it took
                    sessions++;
                        }

                else 
                {
                System.out.println("Sorry "+ userName + ", You've used up all of your guesses! The correct answer was "+ Target + "!");  //This tells the player that they failed to find the number and then tells them what the correct answer  
                }
                {
                Scanner answer = new Scanner(System.in);
                System.out.println("Would you like to play again "+ userName +"? [Y/N]");//This asks the player if they would like to play again
                playagain = answer.nextLine();
               if(playagain.equalsIgnoreCase("Y"))//This is what happens if the player opts to play again
                {
                play = true;
                count = 0;
                count++;

                } else if(playagain.equalsIgnoreCase("N"))//This is what happens if the player opts to exit the game
                {
                    play = false;
                    System.out.println("Thanks for playing "+ userName +"! :) Please come back soon!");

                    System.out.println("The number of goes you had: "+ session +"");
                    System.out.println("The number of times you guessed correctly: "+ sessions +"");
                    PrinterWriter writer = PrinterWriter("Record");
                    writer.println(userName, session, sessions);
                    break;
                }

             }
        }
    }
}

要确定每个会话的最佳分数，您需要做的就是首先保存会话中的计数并与上一个会话进行比较。

所以在你做..while ..之后，它看起来像

int lowestScore = 6;// or max number of guesses

...

while(play == true)
{
    ...

    do...while...
    if(count < lowestScore)
    {
         lowestScore = count;
    }

    ...
}

每当用户开始新的会话时，这会将最低分数与当前分数进行比较。 另外，请注意while语句中的双等号。
