Given an ArrayList and we have to remove some specific record from it in Java.

Here, we are creating an ArrayList and adding 5 elements in it (100, 200, 300, 400 and 500) and further, we are removing 2 elements from index 1 and 3.

To remove an element from ArrayList, we use arrList.remove(index)

Here,

• arrList is an object of "ArrayList" class
• remove is the method of "ArrayList" class, it returns elements from given index.

Consider the program

import java.util.ArrayList;
 
public class ExArrayList {
 
  public static void main(String[] args) {
    ////Creating object of ArrayList
    ArrayList arrList = new ArrayList();
   
    //adding data to the list
    arrList.add("100");
    arrList.add("200");
    arrList.add("300");
    arrList.add("400");
    arrList.add("500");
   
    System.out.println("Array List elements: ");
    //display elements of ArrayList
    for(int iLoop=0; iLoop < arrList.size(); iLoop++)
      System.out.println(arrList.get(iLoop));
   
    //removing some of the elements
    //removing two elements from index 1 and 3
    arrList.remove(1);
    arrList.remove(3);
    
    
    System.out.println("Array List elements: ");
    //display elements of ArrayList after removing 
    for(int iLoop=0; iLoop < arrList.size(); iLoop++)
      System.out.println(arrList.get(iLoop));
  
  }
}

Output

Array List elements: 
100
200
300
400
500
Array List elements: 
100
300
400
