Based on the following UML diagram, the Student class has been defined in Java. Inside the driver method, if the first instantiation statement assigns "John" and $1111$ for the datafields 'name' and $\text{'}$id$\text{'}$ referred to by $$1,$ what would the second instantiation$-$statement assign to $t..$ elds 'name' and $\text{'}$id$\text{'}$ referred to by the reference variabie $S2.$

Student S$1=$ new Student$()$;

Student $S2=$ new Student$()$;
