Second: Consider using the builder when you encounter multiple constructor parameters

When you encounter objects that require multiple parameters (parameters can be divided into required and non-required parameters) in order to instantiate an object of a class, there are generally three methods:

1. Overlapping constructors

It is possible to overlap the constructor, but when there are many parameters, the client's code is difficult to write and the container is faulted.

Class of 2.JavaBean type

The setter method is used to set the value of field for the instance object.

3. Using the Builder
