The trait Idable provides a method equalsId that in turn relies on the
method getId(). If this method does not exist on a class mixing in this
trait, the method will fail.
Adding the getId() as an abstract method to the trait will make sure it
is available.

This check looks for methods that are used by a trait but not required by it.
To illustrate, let’s look at the following code example
The trait

getId()as an abstract method to the trait will make sure it is available.
