I need a Java developer

In this we will create a Data Structure that represents a Generic Magic Cup. In our lab we should create a generic interface for Magic items and it should be called Magic, as well as creating a generic class called Magic Cup that implements magic. All magical items should give you the ability to show whats in the item, to empty the item, place an item inside of it, or compare the magic item to another item. A magic cup should be able to hold any item of any type. We should be able to check a cup to see if it is currently empty or if it contains an item. Imagine the cup trick that is commonly done by street artist. To test your work, in a main method you should create a methodology that implements three cups of different type, ie. ints, strings, booleans and even magic cups. Then you should be able to use the method to see if you can find the filed cup or search through all cups to see if magic happened. (In Java and C++)
