What are different ways to iterate over a list?

We can iterate over a list in two different ways – using iterator and using for-each loop.

	List<String> strList = new ArrayList<>();
	//using for-each loop

	for(String obj : strList){
	System.out.println(obj);

	}
	//using iterator

	Iterator<String> it = strList.iterator();
	while(it.hasNext()){

	String obj = it.next();
	System.out.println(obj);

}
