Not necessarily if you have overloaded constructors.
If its not super(), what else you can have? Can you think of a class that is not an Object?

The rules of the Java language say that the parent class's constructor must complete before the child's constructor executes. The is enforced by requiring that the first statement in every constructor (except Object's) is a call to either a parent's constructor or to another constructor in the current class (which will eventually lead to a current class c'tor that invokes a parent c'tor).
