Java Program to Iterate over ArrayList using Lambda Expression

To understand this example, you should have the knowledge of the following Java programming topics:

Example: Pass ArrayList as Function Parameter

import java.util.ArrayList;

class Main {
  public static void main(String[] args) {
    // create an ArrayList
    ArrayList<String> languages = new ArrayList<>();

    // add elements to the ArrayList

    // print arraylist
    System.out.print("ArrayList: ");

    // iterate over each element of arraylist
    // using forEach() method
    languages.forEach((e) -> {
      System.out.print(e + ", ");


ArrayList: Java, Python, JavaScript,

In the above example, we have created an arraylist named languages. Notice the code,

languages.forEach((e) -> {
  System.out.print(e + ", ");

Here, we are passing the lambda expression as an argument to ArrayList forEach().
