class - Inheritance functions in java -

-

this question has answer here:

duplicate of disabling inherited method on derived class

this class codes:

class parent{     public bool sum(int a){return true;}      public int mul(int a){return a*a;}  }

and 2 classes extends parent class: 

class derived extend parent{     //here child can see 2 methods of parent class ,     //i want see sum method in here , don't see mul method } class derivedb extend parent{ //here child can see 2 methods of parent class , //i want here see mul method. }

you can making mul private method in parent class. mul method has visibility inside parent class

class parent{     public bool sum(int a){return true;}      private int mul(int a){return a*a;}  }
