Special keywords are required to access certain members. In case the method you use happens to override the superclass’s method, you can always abort the overridden method by the strategic use of keywords. These keywords are called keywords super. Moreover, the keyword super is also used to access hidden fields.
However, accessing hidden fields is often discouraged. With the super class are special subclasses with specific names. In order to override the command you need to incorporate the keyword super in the right context to allow override of the right class to get the needed result. Hence, the keyword super can be used to access the different variables from the super class.
