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:
Java
Java
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:
Program 2:
AbstractList: [Geeks, for, Geeks, 10, 20] Final AbstractList: [Geeks, for, Geeks, 20]
// 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]
