Java钓鱼游戏中的不等式、循环和计分失败

Question

我正在尝试编写一个钓鱼游戏的代码。但我正在为寻找代码中的失败而苦苦挣扎。其中一个问题是如何进行循环。即使我选Y或Y，游戏也结束了。但是我想要在输入“y”或“y”时对程序进行限制。

另一个问题是：计分是错误的。我该怎么修好它？

import java.util.Random;
import java.util.Scanner;

public class fishinggame {

    public static void main(String[] args) {
        Random dice = new Random();
        Scanner kenny = new Scanner(System.in);
        int randomGuess;
        String choice = "sj";
        int score = 0;
        int points = 0;
        int counter = 0;

        //Opening statement
        System.out.println("Let's go fishing!!!");
        System.out.println();

        System.out.println("Would you like to fish?");
        System.out.println("Type Y or y for yes");
        System.out.println("Type anything for no");

        //Variables set

        // 

        while (choice == "Y" ||choice =="y");{
            randomGuess = dice.nextInt(7);
            choice = kenny.next();

            if (randomGuess == 1){
                System.out.println("You caught an old shoe.");
            points += 1;}

            if (randomGuess == 2){
                System.out.println("You caught a huge fish!");
            points += 100;}

            if (randomGuess == 3){
                System.out.println("You caught a leaf ");
            points += 2;}

            if (randomGuess == 4){
                System.out.println("You caught a small fish ");
            points += 50;}

            if (randomGuess == 5){
                System.out.println("You caught a rock ");
            points += 3;}

            if (randomGuess == 6){
                System.out.println("You caught a garbage ");
                points += 0;}

            System.out.println();

            if (randomGuess == 5)
                System.out.println("You caught: Iggy Azalea's newest album. Burn it. Now. -20");
            points -= 20;

            System.out.println("Would you like to fish?");
            System.out.println("Type 1 for yes");
            System.out.println("Type 2 for no");

            counter++;

        }

        if (!"Y".equals(choice) ||!"y".equals(choice) ) {

            System.out.println("Game Over");
            System.out.println();
            System.out.println("Your final score is: " + (points));

            if (points > 0)
                System.out.println("Yay! you won!");
            if (points < 0)
                System.out.println("Oh no! You lost :(");
            System.out.println("Thanks for playing!");
        }
    }
}

您的语句始终为假:choice==“y”choice==“y”

请阅读如何比较2个字符串在Java：我如何比较字符串在Java？

此外，在您的代码中，选项始终是“sj”。因此choice.equals（“y”）choice.equals（“y”）将始终为false。
