There are two ways to match any one lowercase vowel in python using Regular Expression. One is the general method and other is using the regular expression. Using the general method In the following code, we have matched all the lowercase vowels from the string 'TutRoIals POinT Is A GreAt PlaTfOrm to lEarN '. Here, we did not use regular expression to match. We used the general method to match the lowercase vowels. Example The following example is a program which shows the matching of any one lowercase vowel in python using the general method. string='TutRoIals POinT Is A GreAt ... Read More

The removeLast() method of the java.util.LinkedList class removes and returns the last element of this list.Example:import java.util.*; public class LinkedListDemo {    public static void main(String[] args) {       LinkedList list = new LinkedList();       list.add("Hello");       list.add(2);       list.add("Chocolate");       list.add("10");       System.out.println("LinkedList:" + list);       System.out.println("Last element:" + list.removeLast());       System.out.println("LinkedList:" + list);    } }Output:LinkedList:[Hello, 2, Chocolate, 10] Last element:10 LinkedList:[Hello, 2, Chocolate]

The removeFirst() method of the java.util.LinkedList class removes and returns the first element from this list.Example:import java.util.*; public class LinkedListDemo {    public static void main(String[] args) {       LinkedList list = new LinkedList();       list.add("Hello");       list.add(2);       list.add("Chocolate");       list.add("10");       System.out.println("LinkedList:" + list);       System.out.println("First element:" + list.removeFirst());       System.out.println("LinkedList:" + list);    } }Output:LinkedList:[Hello, 2, Chocolate, 10] First element:Hello LinkedList:[2, Chocolate, 10]

The getLast() method of the class java.util.LinkedList returns the last element in this list.Example:import java.util.*; public class LinkedListDemo {    public static void main(String[] args) {       LinkedList list = new LinkedList();       list.add("Hello");       list.add(2);       list.add("Chocolate");       list.add("10");       System.out.println("LinkedList:" + list);       System.out.println("Last Element :" + list.getLast());    } }Output:LinkedList:[Hello, 2, Chocolate, 10] Last Element :10

The getFirst() method of the class java.util.LinkedList returns the first element of the current list. Example Live Demo import java.util.*; public class LinkedListDemo { public static void main(String[] args) { LinkedList list = new LinkedList(); list.add("Hello"); list.add(2); list.add("Chocolate"); list.add("10"); System.out.println("LinkedList:" + list); System.out.println("First Element :" + list.getFirst()); } } Output LinkedList:[Hello, 2, Chocolate, 10] First Element :Hello

The addLast(E e) method of the java.util.LinkedList class inserts the specified element at the end of this list.Example:import java.util.*; public class LinkedListDemo {    public static void main(String[] args) {       LinkedList list = new LinkedList();       list.add("Hello");       list.add(2);       list.add("Chocolate");       list.add("10");       System.out.println("LinkedList:" + list);       list.addLast("Element");       System.out.println("LinkedList:" + list);    } }Output:LinkedList:[Hello, 2, Chocolate, 10] LinkedList:[Hello, 2, Chocolate, 10, Element]

The addFirst(E e) method of the class java.util.LinkedList inserts the specified element at the beginning of this list.Example:public class LinkedListDemo {    public static void main(String[] args) {       LinkedList list = new LinkedList();       list.add("Hello");       list.add(2);       list.add("Chocolate");       list.add("10");       System.out.println("LinkedList:" + list);       list.addFirst("Element");       System.out.println("LinkedList:" + list);    } }Output:LinkedList:[Hello, 2, Chocolate, 10] LinkedList:[Element, Hello, 2, Chocolate, 10]

The add(int index, E element) method of the java.util.ArrayList class inserts the specified element E at the specified position in this list. It shifts the element currently at that position (if any) and any subsequent elements to the right (will add one to their indices).Exampleimport java.util.ArrayList; public class ArrayListDemo {    public static void main(String[] args) {       ArrayList arrlist = new ArrayList(5);       arrlist.add(15);       arrlist.add(22);       arrlist.add(30);       arrlist.add(40);       arrlist.add(2,25);       for (Integer number : arrlist) {          System.out.println("Number = " + number);       }    } }OutputNumber = 15 Number = 22 Number = 25 Number = 30 Number = 40

The add(E e) method of the java.util.ArrayList class appends the specified element E to the end of the list.Example:import java.util.ArrayList; public class ArrayListDemo {    public static void main(String[] args) {       ArrayList arrlist = new ArrayList(5);       arrlist.add(15);       arrlist.add(20);       arrlist.add(25);       for (Integer number : arrlist) {          System.out.println("Number = " + number);       }    } }Output:Number = 15 Number = 20 Number = 25

The removeRange() method of the ArrayList class removes all of the elements from this List whose index is between fromIndex and toIndex.Exampleimport java.util.*; public class ArrayListDemo extends ArrayList{    public static void main(String[] args) {       ArrayListDemo arrlist = new ArrayListDemo();       arrlist.add(10);       arrlist.add(12);       arrlist.add(31);       System.out.println("The list:" + arrlist);       arrlist.removeRange(0,2);       System.out.println("The list after using removeRange:" + arrlist);    } }OutputThe list:[10, 12, 31] The list after using removeRange:[31]
