Program: How to copy vector to array?


Description:

You can copy all elements of a vector object to an array. By passing an array object to copyInto() method, you can copy content of a vector object to an array.


Code:
package com.java2novice.vector;

import java.util.Vector;

public class MyVectorArrayCopy {

	public static void main(String a[]){
		Vector<String> vct = new Vector<String>();
		vct.add("First");
		vct.add("Second");
		vct.add("Third");
		vct.add("Random");
		System.out.println("Actual vector:"+vct);
		String[] copyArr = new String[vct.size()];
		vct.copyInto(copyArr);
		System.out.println("Copied Array content:");
		for(String str:copyArr){
			System.out.println(str);
		}
	}
}

Output:
Actual vector:[First, Second, Third, Random]
Copied Array content:
First
Second
Third
Random

What is fail-fast in java?
A fail-fast system is nothing but immediately report any failure that is likely to lead to failure. When a problem occurs, a fail-fast system fails immediately. In Java, we can find this behavior with iterators. Incase, you have called iterator on a collection object, and another thread tries to modify the collection object, then concurrent modification exception will be thrown. This is called fail-fast.
Famous Quotations
Never argue with a fool, onlookers may not be able to tell the difference.
