}
}

SubExample() {
FixVariable( 201 );
}

Which modifier should used in place of ****, so that it's subclass 'SubExample' saved in other package can access 'FixVariable()'  method of  it's  super class ?

1.private

2.public

3.protected

4.default(blank)

Answer :

2 & 3

Explanation :

 The protected modifier allows access by derived classes as well as classes in the same package. 

The private prevents any access from another class. 

The default access allows only access within the same package.
