Math in Java. What a struggle. Help. Please. Fast.

You can definitely use package java.util.Math it provides many math methods, for example if you want to do power of numbers, you can use Math.pow(a, b) where b is the power

ResponseEntity incorrectly maps values

Not sure when to use LAZY and EAGER yet, but as far as I know EAGER mean the beans will be loaded together (product -- variant loaded together)? And then what would be the implication of using LAZY on both entities?

ResponseEntity incorrectly maps values

You are right, I even removed the overridden toString and it still works perfectly fine. Problem has probably resolved without my knowledge after switching to DTOs

Though I will admit, it didn't work that well. The problem disappears when I do:

    @Override
    public String toString() {
        return "Variant{" +
            "variantId=" + variantId +
            ", price=" + price +
            ", type='" + type + "'" +
            ", minQuantity=" + minQuantity +
            ", maxQuantity=" + maxQuantity +
            ", version=" + version +
            ", productId=" + (product != null ? product.getProductId() : null) +
            '}';
    }

    @Override
    public String toString() {
        return "Variant{" +
            "variantId=" + variantId +
            ", price=" + price +
            ", type='" + type + "'" +
            ", minQuantity=" + minQuantity +
            ", maxQuantity=" + maxQuantity +
            ", version=" + version +
            ", productId=" + (product != null ? product.getProductId() : null) +
            '}';
    }

Basically overriding the representation

This is the generated mapper by Mapstruct. But as far as I understand my own code, the problem should not be during the logical process I wrote, it's not on the response pre-flight, but is on the flight/post-flight
