must be done in java

Question#1 In the GoF book, List interface is defined as follows interface List int countO; //return the current number of elements in the list Object get(int index); /return the object at the index in the list Object first0; /return the first object in the list Object lastO; /return the last object in the list boolean include(Object obj); /return true is the object in the list void append(Object obj); //append the object to the end of the list void prepend(Object obj); //insert the object to the front of the list void delete(Object obj); /remove the object from the list void deleteLast); /remove the last element of the list void deleteFirst); //remove the first element of the list void deleteAllO; /remove all elements of the list (a) Write a class adapter to adapt Java ArrayList to GoF List interface (b) Write a main program to test your adapters through List interface (c) Same requirement as (a) and (b), but write an object adapter to adapt Java ArrayList to GoF List interface
