Program: How to add all elements of a list to vector?


Description:

Below example shows how to copy or create a vector with another collection object. In the code we have created an ArrayList and by using addAll() method, we can copy another collection object.


Code:
package com.java2novice.vector;

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

public class MyVectorNewCollection {

	public static void main(String a[]){
		Vector<String> vct = new Vector<String>();
		//adding elements to the end
		vct.add("First");
		vct.add("Second");
		vct.add("Third");
		vct.add("Random");
		System.out.println("Actual vector:"+vct);
		List<String> list = new ArrayList<String>();
		list.add("one");
		list.add("two");
		vct.addAll(list);
		System.out.println("After Copy: "+vct);
	}
}

Output:
Actual vector:[First, Second, Third, Random]
After Copy: [First, Second, Third, Random, one, two]

Transient and Volatile Modifiers
Transient: The transient modifier applies to variables only and it is not stored as part of its object's Persistent state. Transient variables are not serialized.

Volatile: Volatile modifier applies to variables only and it tells the compiler that the variable modified by volatile can be changed unexpectedly by other parts of the program.
Famous Quotations
If you don’t make mistakes, you’re not working on hard enough problems. And that’s a big mistake.
