Program: How to copy LinkedList to array?


Description:

Here we can see example for copying all content of LinkedList to an array. You can get this done by calling toArray() method.


Code:
package com.java2novice.linkedlist;

import java.util.LinkedList;

public class MyLinkedListArray {

	public static void main(String a[]){
		
		LinkedList<String> arrl = new LinkedList<String>();
		arrl.add("First");
		arrl.add("Second");
		arrl.add("Third");
		arrl.add("Random");
		System.out.println("Actual LinkedList:"+arrl);
		String[] strArr = new String[arrl.size()];
		arrl.toArray(strArr);
		System.out.println("Created Array content:");
		for(String str:strArr){
			System.out.println(str);
		}
	}
}

Output:
Actual LinkedList:[First, Second, Third, Random]
Created Array content:
First
Second
Third
Random

Inner class and Anonymous class
Inner class: classes defined in other classes, including those defined in methods are called inner classes. An inner class can have any accessibility including private.

Anonymous class: Anonymous class is a class defined inside a method without a name and is instantiated and declared in the same place and cannot have explicit constructors.
Famous Quotations
