Arraylist Remove Java Element Code Example

Example 1: How to remove element from arraylist in java

// Java.util.ArrayList.remove(Object) method example import java.util.ArrayList; import java.util.List; public class ArrayListRemoveObjectMethod {    public static void main(String[] args)    {       List<Integer> al = new ArrayList<>();       al.add(56);       al.add(28);       al.add(39);       al.add(59);       al.add(82);       System.out.println("Before using ArrayList.remove(Object) method size of ArrayList: " + al);       // removes element 56       al.remove(new Integer(56));       // removes element 28       al.remove(new Integer(28));       System.out.println("After using ArrayList.remove(Object) method size of ArrayList: " + al);    } }

Example 2: how to remove an element from an arraylist java

// Java program to demonstrate working of remove  // on an integer arraylist  import java.util.List;  import java.util.ArrayList;     public class GFG  {      public static void main(String[] args)      {          List<Integer> al = new ArrayList<>();          al.add(10);          al.add(30);          al.add(1);          al.add(2);             // This makes a call to remove(int) and           // removes element 20.          al.remove(1);                     // Now element 30 is moved one position back          // So element 30 is removed this time          al.remove(1);             System.out.println("Modified ArrayList : " + al);      }  }
