Example of remove (int index) method 

In this example we will show you how does remove (int index) method works in List interface. This example will help you to understand how can you remove an element at the specific index position of a list. Through this example we will show you adding of element to the list, show the element with their position, size of list,  and deletion of an element at the specified position in a list. 

Example:-

package Devmanuals.com;
import java.util.List;
import java.util.ArrayList;
public class ListRemoveIndex {
public static void main(String args[]){
ArrayList al = new ArrayList ();
al.add("Ram");
al.add("Shyam");
al.add("Ghanshyam");
al.add("Sohan");
al.add("Mohan");
System.out.println("Initial size of list is : "+al.size());
for(int i=0;i<al.size();i++)
System.out.println("Element at the position " +i+"=" +al.get(i));
Object obj=al.remove(2);
System.out.println("The removed element at position 2 is "+obj); 
System.out.println("The new list with their index values are : " );
for(int i=0;i<al.size();i++)
System.out.println("At position " +i + " element is " +al.get(i));
System.out.println("Size of list after removing element i : "+al.size());
}
}
