JAXB stands for Java Architecture for XML Binding

Major components of JAXB are:

• Schema compiler

• Schema generator

• Binding runtime framework

The elements are ordered using their natural ordering, or by a Comparator

• Comparator can provided at set creation time through one of the overloaded constructors.

Provides guaranteed log(n) time cost for the basic operations like add, remove and contains.

Makes no order guarantees.

Permits the null element.

Offers constant time performance for the basic operations like add, remove, contains and size,

• assuming the hash function disperses the elements properly among the buckets.

Sets contain no pair of elements e1 and e2 such that e1.equals(e2), and at most one null element.

• Some implementations may prohibit null elements.

The Set interface places additional stipulations on:

Deque interface supports capacity-restricted deques as well as those with no fixed size limit.

Deque interface defines methods to access the elements at both ends of the deque.

Methods are provided to insert, remove, and examine the element.
