Program: How to delete all elements from my LinkedList?


Description:

Here we can see example for deleting all objects from LinkedList at one method call. We can do this by calling clear() method on LinkedList, it will delete all objects.


Code:
package com.java2novice.linkedlist;

import java.util.LinkedList;

public class ClearMyLinkedList {

	public static void main(String a[]){
		
		LinkedList<String> arrl = new LinkedList<String>();
		//adding elements to the end
		arrl.add("First");
		arrl.add("Second");
		arrl.add("Third");
		arrl.add("Random");
		System.out.println("Actual LinkedList:"+arrl);
		arrl.clear();
		System.out.println("After clear LinkedList:"+arrl);
	}
}

Output:
Actual LinkedList:[First, Second, Third, Random]
After clear LinkedList:[]

Stream and types of Streams
A Stream is an abstraction that either produces or consumes information. There are two types of Streams and they are:

Byte Streams: Provide a convenient means for handling input and output of bytes. Byte Streams classes are defined by using two abstract classes, namely InputStream and OutputStream.

Character Streams: Provide a convenient means for handling input & output of characters. Character Streams classes are defined by using two abstract classes, namely Reader and Writer.
Famous Quotations
There is a great difference between worry and concern. A worried person sees a problem, and a concerned person solves a problem.
