The remove(int index) method of List interface in Java is used to remove an element from the specified index from a List container and returns the element after removing it. It also shifts the elements after the removed element by 1 position to the left in the List.
Syntax:
E remove(int index)
Where, E is the type of element maintained
by this List collection
Parameters: It accepts a single parameter index of integer type which represents the index of the element needed to be removed from the List.
Return Value: It returns the element present at the given index after removing it.
Below program illustrate the remove(int index) method of List in Java:
Program 1:
import java.util.*;
public class GFG {
public static void main(String[] args)
{
List<Integer> list = new ArrayList<Integer>( 5 );
list.add( 5 );
list.add( 10 );
list.add( 15 );
list.add( 20 );
list.add( 25 );
int index = 2 ;
System.out.println( "Initial List: " + list);
list.remove(index);
System.out.println( "Final List: " + list);
}
}
|
Output:
Initial List: [5, 10, 15, 20, 25]
Final List: [5, 10, 20, 25]
Program 2:
import java.util.*;
public class GFG {
public static void main(String[] args)
{
List<String> list = new ArrayList<String>( 5 );
list.add( "Welcome" );
list.add( "to" );
list.add( "Geeks" );
list.add( "for" );
list.add( "Geeks" );
int index = 2 ;
System.out.println( "Initial List: " + list);
list.remove(index);
System.out.println( "Final List: " + list);
}
}
|
Output:
Initial List: [Welcome, to, Geeks, for, Geeks]
Final List: [Welcome, to, for, Geeks]
