Enhanced for loop:
for (String element : array) {
// rest of code handling current element
}
Traditional for loop equivalent:
for (int i=0; i < array.length; i++) {
String element = array[i];
// rest of code handling current element
}

Java for loop vs Enhanced for loop - GeeksforGeeks
July 23, 2025 - The enhanced for loop, also known as the for-each loop, is a streamlined way to iterate over collections and arrays. It eliminates the need for managing the loop's counter or bounds manually.

An enhanced for loop is just limiting the number of parameters inside the parenthesis.
for (int i = 0; i < myArray.length; i++) {
System.out.println(myArray[i]);
}
Can be written as:
for (int myValue : myArray) {
System.out.println(myValue);
}
Can someone explain the enhanced for-loop ? as simple as possible ?
Sure. Say you have an array list of strings (ArrayList list), and you wanted to print out each of the elements in the list. You could do it one of two ways: for (int i = 0; i < list.size(); i++) { System.out.println(list.get(i)); } or method 2: for (String s : list) { System.out.println(s); } This second function is the enhanced for loop. So basically if you're iterating over a list or set, you don't have to write out the full old for loop syntax, you can just write the much more readable enhanced for-loop syntax. Its much more readable because the bounds of the for-loop are very clear (you're iterating over each element of the for loop from start to end) and you immediately have access to each element without calling .get(index). The downsides of the enhanced for-loop is that you don't have access to the index you're at without explicitly keeping track of it, and that it only works on objects that extend the Collections interface, so really only lists and sets. So no enhanced for loops on hashmaps or iterators. More on reddit.com

What's the purpose of using a for-each/enhanced for-loop?
It makes the code easier to read, allows the use of lambdas (in the case of stream()) and eliminates the need for an index variable and a get() operation required by the classic for loop. If, say, you wanted to print the contents of an ArrayList list using a classic for loop, it would look like this: for (int i = 0; i < list.size(); i++) { System.out.println(list.get(i)); } Using an enhanced for loop, it would look like this: for(String s: list) { System.out.println(s); } There is now no need to use an index variable or a get() operation.

April 26, 2019Uses of Enhanced For Loop in Java?
It's not used just to display arrays. It can be used for a variety of things (finding max in an array, finding number of elements that satisfy a criteria, etc). You sound like you are preparing for an exam or something. If so, the teacher using the phrase "enhanced" seems wrong. Should be called a foreach loop (even though each does not appear in the syntax). More on reddit.com

February 13, 2025 - We don't have to keep track of an index or worry about the length of the array. The enhanced for loop takes care of all of this for us. We can also use the enhanced for loop to iterate over a collection. Let's take a look at an example of iterating over an ArrayList of Strings. // Here is the example of an enhanced for loop to iterate over a collection import java.util.ArrayList; public class EnhancedForLoop { public static void main(String[] args) { // use the enhanced for loop to iterate over the `names` ArrayList ArrayList<String> names = new ArrayList<String>(); names.add("Alice"); names.add("Bob"); names.add("Charlie"); for (String name : names) { System.out.println(name); } } }

There is a special kind of loop that can be used with arrays called an enhanced for loop or a for each loop. This loop is much easier to write because it does not involve an index variable or the use of the []. It just sets up a variable that is set to each value in the array successively.

Using enhanced for loop to iterate in reverse order ? (Java in General forum at Coderanch)
Amandeep: You'd have to go through the steps of creating another List/Array, copying the elements in reverse order to the new List/Array, then using the for each loop on that. It should be relatively easy to do. John. ... Or you could use Collections.reverse() to reverse the order of the existing list. But offhand, it's probably easier to just use the old-fashioned for loop. Enhanced for isn't designed to handle everything - it just handles the most common case, and handles it very well.

3 weeks ago - Explanation: In the above example, we use the for-each loop to iterate the list of integer to find the largest or maximum value in the list. Here, we use the Integer.MIN_VALUE which is the minimum value of integer and compare it the element of list and check if the element is greater than the max then update the max value. While the for-each loop is convenient, there are some important limitations to consider:
