Program: How to iterate through LinkedHashSet?


Description:

Below example shows how to read all elements from LinkedHashSet object by using Iterator object.


Code:
package com.java2novice.linkedhashset;

import java.util.Iterator;
import java.util.LinkedHashSet;

public class MyLhsIterateEx {

	public static void main(String a[]){
		LinkedHashSet<String> lhs = new LinkedHashSet<String>();
		//add elements to HashSet
		lhs.add("first");
		lhs.add("second");
		lhs.add("third");
		Iterator<String> itr = lhs.iterator();
		while(itr.hasNext()){
			System.out.println(itr.next());
		}
	}
}

Output:
first
second
third

doPost Vs doGet methods
doGet() method is used to get information, while doPost() method is used for posting information. doGet() requests can't send large amount of information and is limited to 240-255 characters. However, doPost()requests passes all of its data, of unlimited length. A doGet() request is appended to the request URL in a query string and this allows the exchange is visible to the client, whereas a doPost() request passes directly over the socket connection as part of its HTTP request body and the exchange are invisible to the client.
