> A quick article to learn how to loop a list or a map by using Java 8 forEach() method.

In this quick article, you'll learn how to use the `forEach()` method to loop a `List` or a `Map` object in Java 8 and higher.

## Map Example

The following example demonstrates how you can use `forEach()` with lambda expression to loop a `Map` object:

```java
// create a map
Map<String, Integer> salaries = new HashMap<>();
salaries.put("John", 4000);
salaries.put("Alex", 5550);
salaries.put("Emma", 3850);
salaries.put("Tom", 6000);
salaries.put("Bena", 4500);

// print map elements
salaries.forEach((k, v) -> System.out.println(k + " salary is " + v));
```

The above code will output the following:

```bash
Alex salary is 5550
Tom salary is 6000
John salary is 4000
Bena salary is 4500
Emma salary is 3850
```

## List Example

Just like a `Map`, you can also use the `forEach()` method to loop a `List` object in Java 8 and higher:

```java
// create a list
List<String> users = Arrays.asList("John", "Alex", "Emma", "Tom", "Bena");

// print list elements
users.forEach(u -> System.out.println("Hey, " + u));
```

Here is the output of the above program:

```bash
Hey, John
Hey, Alex
Hey, Emma
Hey, Tom
Hey, Bena
```
