Q$1$ MyArrayList class implements ArrayListInterface which specifies only a void method addElement that accepts an integer value to be added as an input parameter. MyArrayList operates similar to the array lists.

a$)$ Write the ArrayListInterface.

b$)$ Write the MyArrayList class with the following data fields: Integer values should be stored in an array named storage. capacity data field stores the capacity of the storage array $($initially it is $2).$ numE lements data field stores the number of elements in the array $($initially it is $0).$ All data fields should be private.

c$)$ Write a default constructor which creates the storage array with the default capacity.

d$)$ Write addElement method which places the input integer at the last available position. If the capacity of the array is not sufficient, it calls resize$()$ method to double the size of storage array before addition operation.

e$)$ Write the private void resize method. Do not use any for & for$-$each loops inside the resize method.

f$)$ Draw UML class diagrams and their relationships for all classes & interfaces.
