Both this and super keywords are non static and cannot be used in static context

From within a constructor, you can also use the this keyword to call another constructor in the same class . Doing so is called an explicit constructor invocation.

super keyword is used to access methods of the parent class while this is used to access methods of the current class . this is a reserved keyword in java i.e, we can’t use it as an identifier. this is used to refer current-class’s instance as well as static members.

super can be used to call parent class’ variables and methods . super() can be used to call parent class’ constructors only.
