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


Description:

Below example shows how to find whether a vector contains list of objects or not. The method containsAll() helps us to find the match.


Code:
package com.java2novice.vector;

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

public class MyElementCheck {

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

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

Prevent a method from being overridden
By specifying final keyword to the method you can avoid overriding in a subcalss. Similarlly one can use final at class level to prevent creating subclasses.
