non-static method add(e) cannot be referenced from a static context

Помогите решить проблему. Не могу понять, в чем моя ошибка. class ProductSearchSrvice находиться в отдельном классе.

import java.util.List;
import java.util.ArrayList;
public class Lab10 {
    public static void main(String[] args){
        List<ProductSearchSrvice> list = new ArrayList<>();
        ProductSearchSrvice shop_1 = new ProductSearchSrvice("Rozetka");
        ProductSearchSrvice shop_2 = new ProductSearchSrvice("OLX");
        ProductSearchSrvice shop_3 = new ProductSearchSrvice("HIKVISION");
        List.add(shop_1);
        List.add(shop_2);
        List.add(shop_3);
    }
}
class ProductSearchSrvice {
    private String name;
    public ProductSearchSrvice(String name) {
        this.name = name;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    @Override
    public String toString() {
        return "ProductSearchSrvice{" +
                "name='" + name + '\'' +
                '}';
    }
}
