In simple way you can do this pal.

Code:

                EmployeeClass[] collection = new EmployeeClass[] {new EmployeeClass(), 
                new EmployeeClass(), new EmployeeClass()};
                
                for(int i = 0; i < collection.length; i ++) {
                    collection[i].getdata();
                }
                for(int j = 0; j < collection.length; j++) {
                    collection[j].display();
                }

What is displayTotal() do. I can't see anything about it.
