The remove(int index) method of java.util.AbstractList class is used to remove an element from an abstract list from a specific position or index.
Syntax:
AbstractList.remove(int index)
Parameters: The parameter index is of integer data type and specifies the position of the element to be removed from the AbstractList.
Return Value: This method returns the element that has just been removed from the list.
Below programs illustrate the AbstractList.remove(int index) method:
Program 1:
// Java code to illustrate remove() method import java.util.*;
import java.util.LinkedList;
public class AbstractListDemo {
public static void main(String args[])
{
// Creating an empty AbstractList
AbstractList<String>
list = new LinkedList<String>();
// Using add() method to add elements in the list
list.add( "Geeks" );
list.add( "for" );
list.add( "Geeks" );
list.add( "10" );
list.add( "20" );
// Output the list
System.out.println( "AbstractList: " + list);
// Remove the head using remove()
list.remove( 3 );
// Print the final list
System.out.println( "Final AbstractList: " + list);
}
} |
Output:
AbstractList: [Geeks, for, Geeks, 10, 20] Final AbstractList: [Geeks, for, Geeks, 20]
Program 2:
// Java code to illustrate remove() when position of // element is passed as parameter import java.util.*;
import java.util.LinkedList;
public class AbstractListDemo {
public static void main(String args[])
{
// Creating an empty AbstractList
AbstractList<String> list = new LinkedList<String>();
// Use add() method to add elements in the list
list.add( "Geeks" );
list.add( "for" );
list.add( "Geeks" );
list.add( "10" );
list.add( "20" );
// Output the list
System.out.println( "AbstractList:" + list);
// Remove the head using remove()
list.remove( 0 );
// Print the final list
System.out.println( "Final AbstractList:" + list);
}
} |
Output:
AbstractList:[Geeks, for, Geeks, 10, 20] Final AbstractList:[for, Geeks, 10, 20]
