Add all collections in ArrayList

In the previous post, we have seen how to add an element at a particular position. In this post, we will see how to add a collection of element to an arrayList.

For this, we use the addall() method to add the collection.

Syntax:

public boolean addAll(Collection c)

Example:

import java.util.ArrayList;

public class ArrayListEx {

	public static void main(String[] args) {
		ArrayList<String> fruits = new ArrayList<String>();
		fruits.add("Apple");
		fruits.add("Orange");
		fruits.add("Mango");
		fruits.add("Grapes");

		System.out.println("Fruits list : "+fruits);
		
		ArrayList<String> vegitables = new ArrayList<String>();
		vegitables.add("carrot");
		vegitables.add("potato");
		vegitables.addAll(fruits);
		System.out.println("Vegitables + Fruits : "+vegitables);
	}
}

Output:
