i have auto class , 3 methods m1(),m2(),m3(). engineer can access m1() , m2()method ,driver can m1() , m3(),but engineer restrict m3()(should not provide accessing method) , driver restrict m2()(should not provide accessing method)method how implement scenario in java class car{

}

declare auto interface m3() method , create engineer interface extends auto interface , has m2() method , driver interface m3() method , extends auto interface.now write concreteengineer class implements engineer interface , concretedriver class implement driver interface.
