Abstract Data Type and Interface

Question

I am new to Java. What is the difference between Abstract data type and Interface.

For Example We have a ListADT

interface MyListADT {
    void          


        

Answer 1

The combination of data with its methods is called an Abstract Data Type (ADT).

A Java Interface is a way to specify an Abstract Data Type (ADT).

You can declare a class as abstract when it contains zero or more abstract methods or When an interface is implemented to a class where not all methods are not implemented.
