A Vector can be converted into an Array using the java.util.Vector.toArray() method. This method requires no parameters and it returns an Array that contains all the elements of the Vector in the correct order.A program that demonstrates this is given as follows −Example Live Demoimport java.util.Vector; public class Demo {    public static void main(String args[]) {       Vector vec = new Vector();       vec.add(7);       vec.add(3);       vec.add(5);       vec.add(2);       vec.add(8);       Object[] arr = vec.toArray();       System.out.println("The Array elements are: ");   ...

The minimum element of a Vector can be obtained using the java.util.Collections.min() method. This method contains a single parameter i.e. the Vector whose minimum element is determined and it returns the minimum element from the Vector.A program that demonstrates this is given as follows −Example Live Demoimport java.util.Collections; import java.util.Vector; public class Demo {    public static void main(String args[]) {       Vector vec = new Vector();       vec.add(7);       vec.add(3);       vec.add(9);       vec.add(5);       vec.add(8);       System.out.println("The Vector elements are: " + vec);     ...

The maximum element of a Vector can be obtained using the java.util.Collections.max() method. This method contains a single parameter i.e. the Vector whose maximum element is determined and it returns the maximum element from the Vector.A program that demonstrates this is given as follows −Example Live Demoimport java.util.Collections; import java.util.Vector; public class Demo {    public static void main(String args[]) {       Vector vec = new Vector();       vec.add(7);       vec.add(3);       vec.add(9);       vec.add(5);       vec.add(8);       System.out.println("The Vector elements are: " + vec);     ...

A ListIterator can be used to traverse the elements in the forward direction as well as the reverse direction in a Vector. The method hasNext( ) in ListIterator returns true if there are more elements in the Vector while traversing in the forward direction and false otherwise. The method next( ) returns the next element in the Vector and advances the cursor position.A program that demonstrates this is given as follows −Exampleimport java.util.ListIterator; import java.util.Vector; public class Demo {    public static void main(String args[]) {       Vector vec = new Vector();       vec.add(3);     ...

An Iterator can be used to loop through the Vector elements. The method hasNext( ) returns true if there are more elements in the Vector and false otherwise. The method next( ) returns the next element in the Vector and throws the exception NoSuchElementException if there is no next element.A program that demonstrates this is given as follows −Example Live Demoimport java.util.Iterator; import java.util.Vector; public class Demo {    public static void main(String args[]) {       Vector vec = new Vector();       vec.add(4);       vec.add(1);       vec.add(3);       vec.add(9);     ...

The Vector elements can be traversed using the Enumeration interface. The method hasMoreElements( ) returns true if there are more elements to be enumerated and false if there are no more elements to be enumerated. The method nextElement( ) returns the next object in the enumeration.A program that demonstrates this is given as follows −Example Live Demoimport java.util.Enumeration; import java.util.Vector; public class Demo {    public static void main(String args[]) {       Vector vec = new Vector();       vec.add(7);       vec.add(3);       vec.add(5);       vec.add(9);       vec.add(2);     ...

The first element in the Vector can be obtained using the java.util.Vector.firstElement() method. The last element in the Vector can be obtained using the java.util.Vector.lastElement() method. Neither of these methods requires any parameters.A program that demonstrates this is given as follows:Example Live Demoimport java.util.Vector; public class Demo { public static void main(String args[]) { Vector vec = new Vector(); vec.add(4); vec.add(7); vec.add(2); vec.add(8); ...

The java.util.Vector.setSize() method can be used to set the size of a Vector in Java. If the new size that is set is greater than the old size of the Vector, then null values are added to the positions created. If the new size that is set is lesser than the old size of the Vector, then the elements at positions more than the new size are discarded.A program that demonstrates this is given as follows:Example Live Demoimport java.util.Vector; public class Demo { public static void main(String args[]) { Vector vec = ...

All the elements of a vector can be replaced by a specific element using java.util.Collections.fill() method. This method requires two parameters i.e. the Vector and the element that replaces all the elements in the Vector. No value is returned by the Collections.fill() method.A program that demonstrates this is given as follows:Example Live Demoimport java.util.Collections; import java.util.Vector; public class Demo { public static void main(String args[]) { Vector vec = new Vector(5); vec.add(7); vec.add(4); vec.add(1); ...

An element of a Vector can be searched using the method java.util.ArrayList.indexOf(). This method returns the index of the first occurrence of the element that is specified. If the element is not available in the Vector, then this method returns -1.A program that demonstrates this is given as follows:Example Live Demoimport java.util.Vector; public class Demo { public static void main(String args[]) { Vector vec = new Vector(5); vec.add(4); vec.add(1); vec.add(7); ...
