Whether the list record in Java exactly matches the method

Today I want to talk about grouping the list and then encapsulating it with map. Maybe you still have some ambiguity after reading it.

Let's take a look at the project structure chart:

The user class is a VO class, and the main logic is on maptestbak.

Operation effect:

schematic diagram:

1. There are two groups of three people in the starslist

2. There is a group of two people in dollist

3. After the marched operation, a group of people are matched to the result. The first group.

The principle is simple.
