Chapter: Data Structures Last Updated: 11-08-2017 09:26:15 UTC

Program:

            /* ............... START ............... */
                
import java.util.ArrayList;
import java.util.List;

public class JavaListArrayList {
	public static void main(String a[]) {
		ArrayList<String> arrl = new ArrayList<String>();
		// adding elements to the end
		arrl.add("Java");
		arrl.add("Scan");

		System.out.println("Actual ArrayList:" + arrl);
		List<String> list = new ArrayList<String>();
		list.add("one");
		list.add("two");
		arrl.addAll(list);
		System.out.println("After Copy: " + arrl);
	}
}
                /* ............... END ............... */
        

Output

Actual ArrayList:[Java, Scan]
After Copy: [Java, Scan, one, two]

Notes:

  • If you have another list that contains all the items you would like to add you can do arrl.addAll(list).
