LinkedList size() Method in Java
The Java.util.LinkedList.size() method is used to get the size of the Linked list or the number of elements present in the linked list.
Syntax:
LinkedList.size()
Parameters: This method does not take any parameter.
Return Value: This method returns the size or the number of elements present in the LinkedList.
Below program illustrates the Java.util.LinkedList.size() method:
Example 1:
Java
import java.io.*;
import java.util.LinkedList;
public class LinkedListDemo {
public static void main(String args[])
{
LinkedList<String> list = new LinkedList<String>();
list.add( "Geeks" );
list.add( "for" );
list.add( "Geeks" );
list.add( "10" );
list.add( "20" );
System.out.println( "LinkedList:" + list);
System.out.println(
"The size of the linked list is: "
+ list.size());
}
}
|
In Java, the LinkedList class provides the size() method to get the number of elements in the list. The method returns an integer representing the number of elements in the list.
Example 2:
Java
import java.util.LinkedList;
public class Example {
public static void main(String[] args)
{
LinkedList<String> list = new LinkedList<>();
list.add( "apple" );
list.add( "banana" );
list.add( "orange" );
list.add( "grape" );
System.out.println( "Original list:" );
System.out.println(list);
int size = list.size();
System.out.println( "Size of list: " + size);
}
}
|
Output
Original list:
[apple, banana, orange, grape]
Size of list: 4
In this example, we first create a LinkedList object and add four elements to it. The System.out.println() statement prints the original list to the console.
We then use the size() method to get the number of elements in the list, and print the size to the console.
