I need to pass two Objects as parameters while creating Hash Map.One Object as Key and Other as Value.Is it possible using Hash Map?

What I have tried:

Map m=new HashMap();
Employee e=new Employee(1,"Rajesh");
Department d=new Department(10,1);//1 is employee id here 


What is the wrong Iam doing

I think you need to declare the types used in the map. something like:
Map m = new HashMap<Employee, Department>();
