this() is used to invoke a constructor of the same class

super() is used to invoke a super class constructor and

Example of using this():
public Pet(int id) {
this.id = id; // “this” means this object
}
public Pet (int id, String type) {
this(id); // calls constructor public Pet(int id)
this.type = type; // ”this” means this object
}

Example of using super():

If a class called “SpecialPet” extends your “Pet” class then
you can
use the keyword “super” to invoke the superclass’s
constructor. E.g.
public SpecialPet(int id) {
super(id); //must be the very first statement in the
constructor.
}

To call a regular method in the super class use:
“super.myMethod( );”. This can be called at any line.
