TreeSet subSet Example TreeSet class subSet example. public NavigableSet subSet(Object fromElement, boolean fromInclusive, Object toElement, boolean toInclusive) Returns a view of the portion of this set whose elements range from fromElement to toElement. If fromElement and toElement are equal, the returned set is empty unless fromExclusive and toExclusive are both true.

TreeSet size Example TreeSet class size example.public int size() Returns the number of elements in this set (its cardinality).

TreeSet remove Example TreeSet class remove example.public boolean remove(Object o) Removes the specified element from this set if it is present. More formally, removes an element e such that (o==null ? e==null : o.equals(e)), if this set contains such an element

TreeSet pollLast Example TreeSet class pollLast example. public Object pollLast() Retrieves and removes the last (highest) element, or returns null if this set is empty.

TreeSet pollFirst Example TreeSet class pollFirst example. public Object pollFirst() Retrieves and removes the first (lowest) element, or returns null if this set is empty.

TreeSet lower Example TreeSet class lower example. public Object lower(Object e) Returns the greatest element in this set strictly less than the given element, or null if there is no such element.

TreeSet last Example TreeSet class last example.public Object last() Returns the last (highest) element currently in this set.

TreeSet iterator Example TreeSet class iterator example.public Iterator iterator() Returns an iterator over the elements in this set in ascending order.

TreeSet isEmpty Example TreeSet class isEmpty example. public boolean isEmpty() Returns true if this set contains no elements.

TreeSet higher Example TreeSet class higher example.Object higher(Object) Returns the least element in this set strictly greater than the given element, or null if there is no such element.

TreeSet headSet Example TreeSet class headSet example.Returns a view of the portion of this set whose elements are less than (or equal to, if inclusive is true) toElement. The returned set is backed by this set, so changes in the returned set are reflected in this set, and vice-versa. The returned set supports all optional set operations that this set supports.

TreeSet headSet Example TreeSet class headSet example.public SortedSet headSet(Object) Returns a view of the portion of this set whose elements are strictly less than toElement. The returned set is backed by this set, so changes in the returned set are reflected in this set, and vice-versa. The returned set supports all optional set operations that this set supports.

TreeSet floor Example TreeSet class floor example.public Object floor(Object) Returns the greatest element in this set less than or equal to the given element, or null if there is no such element.

TreeSet first Example TreeSet class first example. Object first() Returns the first (lowest) element currently in this set.

TreeSet descendingSet Example TreeSet class descendingSet example.public NavigableSet descendingSet() Returns a reverse order view of the elements contained in this set. The descending set is backed by this set, so changes to the set are reflected in the descending set, and vice-versa.

TreeSet descendingIterator Example TreeSet class descendingIterator example.descendingIterator public Iterator descendingIterator() Returns an iterator over the elements in this set in descending order.

TreeSet contains Example TreeSet class contains example.public boolean contains(Object o) Returns true if this set contains the specified element. More formally, returns true if and only if this set contains an element e such that (o==null ? e==null : o.equals(e)).

TreeSet clone Example TreeSet class clone example.public Object clone() Returns a shallow copy of this TreeSet instance. (The elements themselves are not cloned.)

TreeSet clear Example TreeSet class clear example.public void clear() Removes all of the elements from this set. The set will be empty after this call returns.

Hashtable ceiling Example Hashtable class ceiling example.public Object ceiling(Object) Returns the least element in this set greater than or equal to the given element, or null if there is no such element.

TreeSet addAll Example TreeSet class addAll example. public boolean addAll(Collection c) Adds all of the elements in the specified collection to this set.

Vector class ensureCapacity(int minCapacity)method example Vector class ensureCapacity(int minCapacity)method example. This example shows you how to use ensureCapacity(int minCapacity)method.This method Increases the capacity of this vector, if necessary, to ensure that it can hold at least the number of components specified by the minimum capacity argument.

Vector class elements() method example Vector class elements()method example. This example shows you how to use elements()method.This method Returns an enumeration of the components of this vector.

Vector class copyInto(Object[] anArray)method example Vector class copyInto(Object[] anArray)method example. This example shows you how to use copyInto(Object[] anArray)method.This method Copies the components of this vector into the specified array.

Vector class containsAll(Collection c)method example Vector class containsAll(Collection c)method example. This example shows you how to use containsAll(Collection c)method.This method Returns true if this Vector contains all of the elements in the specified Collection

Vector class contains(Object o)method example Vector class contains(Object o)method example. This example shows you how to use contains(Object o) method.This method Returns true if this vector contains the specified element.

Vector class clone()method example Vector class clone()method example. This example shows you how to use clone()method.This method Returns a clone of this vector.

Vector class clear()method example Vector class clear()method example. This example shows you how to use clear()method.This method Removes all of the elements from this Vector.

Vector class capacity()method example Vector class capacity()method example. This example shows you how to use capacity()method.This method Returns the current capacity of this vector.

Vector class addElement(E obj)method example Vector class addElement(E obj)method example. This example shows you how to use addElement(E obj) method.This method Adds the specified component to the end of this vector, increasing its size by one.
