add element at specific index in arraylist java code example

Example 1: arraylist insert at position

//Insert a value by using arrayName.add(index, value)
//Will not remove current element at index. Will simply move all elements to
//the right.
import java.util.ArrayList;
public class main{
  public static void main(String[] args){
   ArrayList<Integer> list = new ArrayList<Integer>();
   	list.add(0);
    list.add(1);
    list.add(2);
    list.add(3);
    list.add(4);
    list.add(5);
    list.add(0, 100);
    
    //enhanced for loop will print all elements of the ArrayList
    for(int element : list){
    System.out.print(list + ", ");
      }
    //Expected output: "100, 0, 1, 2, 3, 4, 5, "
  }
  
}

Example 2: arraylist adding at index

public void add(int index, E element)
// adding element 25 at third position
arrlist.add(2,25);

Example 3: arraylist add at index

arrlist.add(2,25);
