Dynamically adding elements to ArrayList in Groovy

Dynamically adding elements to ArrayList in Groovy

In Groovy, you can dynamically add elements to an ArrayList using its add() method or by using the << operator. Here's how you can do it:

Using the add() method:

// Create an ArrayList def list = new ArrayList<String>() // Add elements dynamically list.add("Item 1") list.add("Item 2") list.add("Item 3") // Display the ArrayList println(list)

Using the << operator:

// Create an ArrayList def list = new ArrayList<String>() // Add elements dynamically list << "Item 1" list << "Item 2" list << "Item 3" // Display the ArrayList println(list)

Both methods achieve the same result, which is adding elements to the ArrayList. You can use the one that you find more concise and readable. The << operator is often preferred for its brevity.

You can also add elements of different types to an ArrayList since Groovy is a dynamically typed language.
