# Sub-dependencies { #sub-dependencies }

You can create dependencies that have **sub-dependencies**.

They can be as **deep** as you need them to be.

**FastAPI** will take care of solving them.

## First dependency "dependable" { #first-dependency-dependable }

You could create a first dependency ("dependable") like:

   * <p>The overall principle is to continue to treat every checked exception as a checked

   * new stack trace matches that of the current thread.

   * <p>Instances of {@code exceptionClass} are created by choosing an arbitrary public constructor
