This code would call all of the parents constructors or methods. Is that correct?

super() will call the conctructor of you extending class. Also if used it must be the first line in a contructor method.
For example:

// PARENT CLASS

// CHILD CLASS


Calling super is only neccessay if you have code in the constructor that needs initialising.
Else you can happy invoke its methods (assuming they are visible (public, protected etc)).
super.someParentMethod();
Hope that helps.

No. super() would only invode the superclass constructor that takes no arguments.
