Differences between simple factories and factory methods: Simple factories and factory method patterns look very similar, especially specific factories in simple factories and factory methods.

It has a total of 13,000 species in the world, most of which are herbs, as well as some woody plants and lianas. When we look at their flowers, they look like a flower, but they are actually dozens of small flowers that are tightly together. They chose to gather together to attract the attention of insects. Because if each small flower grows independently, they do not have much attraction to insects, but when they gather together in inflorescence like this, they will form a bright yellow flag that insects cannot refuse.
