How many ways to iterate the elements of the collection in java

There are various ways to traverse the collection elements:

1. By Iterator interface.
2. By for-each loop.
3. By ListIterator interface.
4. By for loop.
5. By forEach() method.
6. By forEachRemaining() method.

Iterating Collection through Iterator interface

Let's see an example to traverse ArrayList elements using the Iterator interface.

import java.util.*;  

class ArrayList2{  

 public static void main(String args[]){  

  ArrayList<String> list=new ArrayList<String>();//Creating arraylist  

  list.add("Ravi");//Adding object in arraylist  

  list.add("Vijay");  

  list.add("Ravi");  

  list.add("Ajay");  

  //Traversing list through Iterator  

  Iterator itr=list.iterator();  

  while(itr.hasNext()){  

   System.out.println(itr.next());  

  }  

 }  

}
