Java's Arraylist can provide you this feature. Java program to iterate through an arraylist of objects with Java 8 stream API. Java provides a way to use the “for” loop that will iterate through each element of the array. The constant factor is low compared to that for the LinkedList implementation. forEach() method in the List has been inherited from java.lang.Iterable and removeIf() method has been inherited from java.util.Collection. Here is the code for the array that we had declared earlier- for (String strTemp : arrData){ System.out.println(strTemp); } You can see the difference between the loops. As elements are added to an ArrayList, its capacity grows automatically. There are 7 ways you can iterate through List.
