Description of PR

According to the documentation of ToStringBuilder the method setDefaultStyle() should only be called once since it sets a Singleton value.
Fixed by passing ToStringStyle as an parameter to ToStringBuilder constructor directly.

The primary branch is now main, so if you can update the additional class and change the destination branch, this looks good to move forward.
