Below program illustrate the remove[int index] method of List in Java:
Program 1:
|
// Program to illustrate the
// remove[int index] method
import java.util.*;
public class GFG {
public static void main[String[] args]
{
// Declare an empty List of size 5
List list = new ArrayList[5];
// Add elements to the list
list.add[5];
list.add[10];
list.add[15];
list.add[20];
list.add[25];
// Index from which you want to remove element
int index = 2;
// Initial list
System.out.println["Initial List: " + list];
// remove element
list.remove[index];
// Final list
System.out.println["Final List: " + list];
}
}

Program 2:
|
// Program to illustrate the
// remove[int index] method
import java.util.*;
public class GFG {
public static void main[String[] args]
{
// Declare an empty List of size 5
List list = new ArrayList[5];
// Add elements to the list
list.add["Welcome"];
list.add["to"];
list.add["Geeks"];
list.add["for"];
list.add["Geeks"];
// Index from which you want
// to remove element
int index = 2;
// Initial list
System.out.println["Initial List: " + list];
// remove element
list.remove[index];
// Final list
System.out.println["Final List: " + list];
}
