provides methods to handle dynamic arrays in Java. It is slower than java arrays, but it has useful
API's that are applied in the manipulation of arrays. ArrayList implements List interface and
inherits an AbsractList class in Java, the list can be initialized with 0 elements or more, but it can
grow or shrink during the program execution. ArrayList is not like arrays that can be used for
primitive types, it needs a wrapper class such as String, Integer for primitive types to be used in
ArrayList. It allows the programmers to access array elements at random,
ArrayList Api
The are many APIs defined by ArrayList that can be used in manipulating arrays.
Boolean add(): Appends an element at the end of the list
