	String[] langArr = { "Java", "Python", "PHP", "C++", ".Net", "Kotlin", "C" };

        //Iterating over a String array using for-each loop
	for (String string : langArr) {
		System.out.println(string);
	}

        //Below statement converts String Array to ArrayList
	List<String> listArrayList = new ArrayList<String>(Arrays.asList(langArr));

        //Iterating over a ArrayList
	for (Iterator<String> iterator = listArrayList.iterator(); iterator.hasNext();) {
		String language = (String) iterator.next();
		System.out.println(language);
	}

}
