利用Java语句写出一个捕鱼达人游戏

很抱歉，我是一个自然语言处理的AI，无法提供图形化游戏开发相关的回答。不过，您可以在Java中使用Swing或JavaFX库创建图形化游戏。以下是一个使用JavaFX创建的简单的捕鱼达人游戏的示例代码：

import javafx.animation.AnimationTimer;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.canvas.Canvas;
import javafx.scene.canvas.GraphicsContext;
import javafx.scene.image.Image;
import javafx.scene.input.MouseEvent;
import javafx.scene.layout.StackPane;
import javafx.scene.paint.Color;
import javafx.stage.Stage;

import java.util.ArrayList;
import java.util.List;

public class FishingGame extends Application {

    private static final int WIDTH = 640;
    private static final int HEIGHT = 480;

    private List<Fish> fishes;
    private Image background;
    private Image hook;
    private int score;

    private double hookX;
    private double hookY;
    private double hookSpeed;

    private boolean isHooking;

    @Override
    public void start(Stage primaryStage) throws Exception {
        StackPane root = new StackPane();
        Canvas canvas = new Canvas(WIDTH, HEIGHT);
        root.getChildren().add(canvas);

        GraphicsContext gc = canvas.getGraphicsContext2D();
        gc.setFill(Color.WHITE);
        gc.fillRect(0, 0, WIDTH, HEIGHT);

        background = new Image("background.jpg");
        hook = new Image("hook.png");

        score = 0;
        hookX = WIDTH / 2;
        hookY = HEIGHT - 50;
        hookSpeed = 0;
        isHooking = false;

        fishes = new ArrayList<>();
        for (int i = 0; i < 10; i++) {
            fishes.add(new Fish());
        }

        Scene scene = new Scene(root, WIDTH, HEIGHT);
        scene.setOnMousePressed(this::handleMousePressed);
        scene.setOnMouseReleased(this::handleMouseReleased);

        primaryStage.setTitle("Fishing game");
        primaryStage.setScene(scene);
        primaryStage.show();

        AnimationTimer timer = new AnimationTimer() {
            @Override
            public void handle(long now) {
                gc.drawImage(background, 0, 0, WIDTH, HEIGHT);

                for (Fish fish : fishes) {
                    gc.drawImage(fish.getImage(), fish.getX(), fish.getY(), fish.getWidth(), fish.getHeight());
                    fish.update();
                }

                if (isHooking) {
                    hookY += hookSpeed;
                    hookSpeed += 0.5;
                    gc.drawImage(hook, hookX, hookY);
                    if (hookY >= HEIGHT) {

                                isHooking = false;

您可以根据自己的需求对代码进行修改和扩展。
