In Java we can achieve the dynamic array using arraylist.
ArrayList class available on util package, so we don’t need to import any extra packages, In below example 

• created new arraylist
• added value to arraylist
• printing the array list value by using for loop 

Example

import java.util.ArrayList;
import java.util.List;

public class ArrayListExample {
	  public static void main(String[] args) {
      List arrayList = new ArrayList();
      arrayList.add("Java");
      arrayList.add("Java 8");
      arrayList.add("Java 11");
      for (int i = 0; i < arrayList.size(); i++) {
    System.out.println("Value at the index of " + i + " "+arrayList.get(i));
     }
   }
}

Output

Value at the index of 0 Java
Value at the index of 1 Java 8
Value at the index of 2 Java 11
