When a method parameter or a constructor parameter has the same name as an instance variable, this can be used to differentiate between the instance variable and the parameter. this is used to access the current class members. Constructor Invocation. It can be used to invoke another constructor of the same class. this(arguments). The super keyword is used to refer to the immediate parent class of the current object. It is used to access methods and variables of the superclass. Constructor Invocation. It can be used to invoke a constructor of the superclass. This is useful when the superclass has a parameterized constructor that needs to be called from the subclass constructor.
