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

Transient and Volatile Modifiers
Transient: The transient modifier applies to variables only and it is not stored as part of its object's Persistent state. Transient variables are not serialized.

Volatile: Volatile modifier applies to variables only and it tells the compiler that the variable modified by volatile can be changed unexpectedly by other parts of the program.
