how to copy vector to array in java?


The java.util.Vector class implements a growable array of objects. Like an array, it contains components that can be accessed using an integer index. However, the size of a Vector can grow or shrink as needed to accommodate adding and removing items after the Vector has been created. It extends AbstractList and implements List interfaces.

The copyInto() method is used to copy vector to array in java.

Example:

package com.codesjava;
 
import java.util.Vector;
 
public class Test {
  public static void main(String args[]){
	Vector<String> vector = new Vector<String>();
        //adding elements to the end
	vector.add("Jai");
	vector.add("Mahesh");
	vector.add("Hemant");
	vector.add("Vishal");
	System.out.println("Actual vector:"+vector);
	String[] copyArray = new String[vector.size()];
	vector.copyInto(copyArray);
        System.out.println("Copied Array content:");
        for(String string:copyArray){
            System.out.println(string);
        }
  }
}

Output

Actual vector:[Jai, Mahesh, Hemant, Vishal]
Copied Array content:
Jai
Mahesh
Hemant
Vishal
