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


Description:

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.


Code:
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));
	}
}

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

Exception Vs Error
An error is an irrecoverable condition occurring at runtime like out of memory error. These kind of jvm errors cannot be handled at runtime. Exceptions are because of condition failures, which can be handled easily at runtime.
Famous Quotations
I don’t know the key to success, but the key to failure is trying to please everybody.
