这段代码是使用 Python 编写的，如果你需要用 Java 实现类似的功能，可以使用 JavaFX 框架来创建 GUI 界面。以下是 JavaFX 实现类似的代码：

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.layout.StackPane;
import javafx.scene.paint.Color;
import javafx.scene.text.Font;
import javafx.stage.Stage;

import java.util.Random;

public class Love extends Application {

    private final Random random = new Random();

    @Override
    public void start(Stage primaryStage) {
        // 创建心形标签
        Label heartLabel = new Label("❤");
        heartLabel.setFont(Font.font("Comic Sans MS", 500));
        heartLabel.setTextFill(Color.PINK);

        // 创建场景
        StackPane heartPane = new StackPane();
        heartPane.getChildren().add(heartLabel);
        Scene heartScene = new Scene(heartPane, primaryStage.getWidth(), primaryStage.getHeight());

        // 创建小心心标签
        Label loveLabel = new Label("I LOVE YOU!");
        loveLabel.setFont(Font.font("Comic Sans MS", 15));
        loveLabel.setTextFill(Color.WHITE);
        loveLabel.setStyle("-fx-background-color: pink;");
        loveLabel.setPrefWidth(200);
        loveLabel.setPrefHeight(50);

        // 循环创建窗口显示小心心
        for (int i = 0; i < 50; i++) {
            Stage loveStage = new Stage();
            loveStage.setTitle("❤");
            loveStage.setX(random.nextInt((int) (primaryStage.getWidth() - loveLabel.getPrefWidth())));
            loveStage.setY(random.nextInt((int) (primaryStage.getHeight() - loveLabel.getPrefHeight())));
            loveStage.setScene(new Scene(new StackPane(loveLabel)));
            loveStage.show();
        }

        // 显示心形窗口
        primaryStage.setTitle("❤");
        primaryStage.setScene(heartScene);
        primaryStage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}

需要注意的是，JavaFX 库需要 JDK 8 以上版本才能使用。
