Remove Explicit Call To super()

Description

If a constructor does not explicitly invoke a superclass constructor, the Java compiler automatically inserts a call to the no-argument constructor of the superclass. Hence, there is no need to explicitly call the default constructor of the super class.

Benefits

Improves the readability by removing unnecessary lines of code.
