Collections = Provides utility methods for manipulating collections, such as sorting, shuffling, and searching Arrays = Contains utility methods for working with arrays, such as sorting and searching Iterators = An interface that provides methods to iterate over a collection ListIterator = An interface that extends Iterator and provides additional methods to iterate bidirectionally and modify the list during iteration

Generics = Introduced in Java 5, allows you to write classes and methods that can work with any data type Concurrency Collection Classes = Introduced in Java 5, provides thread-safe collection classes, such as ConcurrentHashMap and CopyOnWriteArrayList Comparator = An interface for comparing objects.
