从Arraylist中删除重复数据(机型名称和价格)，并在android中使用Price(添加)添加机型

ArrayList<String> models = new ArrayList<>();
ArrayList<Double> prices = new ArrayList<>();

models.add("机型1");
prices.add(1000.0);
models.add("机型2");
prices.add(1500.0);
models.add("机型3");
prices.add(2000.0);

HashSet<String> uniqueModels = new HashSet<>();
HashSet<Double> uniquePrices = new HashSet<>();

for (int i = 0; i < models.size(); i++) {
    String model = models.get(i);
    double price = prices.get(i);
    
    if (!uniqueModels.contains(model)) {
        uniqueModels.add(model);
        uniquePrices.add(price);
    }
}

models.clear();
prices.clear();

models.addAll(uniqueModels);
prices.addAll(uniquePrices);

public class Price {
    private String model;
    private double price;
    
    public Price(String model, double price) {
        this.model = model;
        this.price = price;
    }
    
    // 添加getter和setter方法
}

ArrayList<Price> prices = new ArrayList<>();

Price price1 = new Price("机型1", 1000.0);
prices.add(price1);

Price price2 = new Price("机型2", 1500.0);
prices.add(price2);

Price price3 = new Price("机型3", 2000.0);
prices.add(price3);
