Program: How to find does ArrayList contains all list elements or not?

Here we can see example for finding whether the instance of an ArrayList contains all objects of another Collection instance. Here we are checking with another List instance.

package com.java2novice.arraylist;

import java.util.ArrayList;
import java.util.List;

public class MyElementCheck {

	public static void main(String a[]){
		ArrayList<String> arrl = new ArrayList<String>();
		arrl.add("First");
		arrl.add("Second");
		arrl.add("Third");
		arrl.add("Random");
		List<String> list = new ArrayList<String>();
		list.add("Second");
		list.add("Random");
		System.out.println("Does ArrayList contains all list elements?: "
					+arrl.containsAll(list));
		list.add("one");
		System.out.println("Does ArrayList contains all list elements?: "
					+arrl.containsAll(list));
	}
}

Does ArrayList contains all list elements?: true
Does ArrayList contains all list elements?: false
