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");
      // Trim Array List
      arrlist1.trimToSize();

    }
  }
}

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");

// Trim Array List

arrlist1.trimToSize();

// Print Array List

for (String value : arrlist1) {

System.out.println("List Element : " + value);

}

List Element : A
List Element : B
List Element : C
