import java.util.ArrayList;
public class ArrayListExamples {
  public static void main(String args[]) {
    // Create ArrayList 1
    ArrayList<String> arrlist1 = new ArrayList<String>(5);
    // Fill Elements in ArrayList 1
    arrlist1.add("A");
    arrlist1.add("B");
    arrlist1.add("C");
    arrlist1.add("D");
    arrlist1.add("E");
    arrlist1.add("F");
    // Remove Element 
    boolean ele = arrlist1.remove("B");
    // Print Array List
    System.out.println("Array List : " + arrlist1);
  }
}

package com.c4learn.arraylist;

import java.util.ArrayList;

public class ArrayListExamples {

public static void main(String args[]) {

// Create ArrayList 1

ArrayList<String> arrlist1 = new ArrayList<String>(5);

// Fill Elements in ArrayList 1

arrlist1.add("A");

arrlist1.add("B");

arrlist1.add("C");

arrlist1.add("D");

arrlist1.add("E");

arrlist1.add("F");

// Remove Element

boolean ele = arrlist1.remove("B");

// Print Array List

System.out.println("Array List : " + arrlist1);

}

Output :

Array List : [A, C, D, E, F]

1	Array List : [A, C, D, E, F]
