13 to 15 Java Questions

I have noticed that multiple times in a week I wake up and check my phone for the time and it is 04:47 AM. Given that I live in the Twin Cities of Minneapolis and St. Paul, there is some day light at that time. I recall a few years ago when I would get up around 05:00 AM to walk the dogs.

I do have an alarm set for 05:00 AM 7 days a week. In addition I have set an appointment in my Google calendar for the same time. Today after waking up at 04:47 AM I checked the calendar to see if there was a message or notification set for 15 minutes before (04:45 AM). Both notification and email are set for 05:00 AM.

I am aware that the brain is able to keep time (to some extent) and let us know that we should go to sleep and also when should we wake up. I just find it interesting how the mechanism works. The main drawback is that it lacks consistency. Sometimes I wake up earlier and a few times it is the sound of the alarm in my phone. Go figure.

Let’s continue with some more questions and answers from the freeCodeCamp article Review these 50 questions to crack your Java programming interview.

Following is the source code for the main() for this post:

package com.canessa.listsandsets;

/*
 * 
 */
public class Solution {

	// **** ****
	public static void main(String[] args) {

		// **** experiment with lists ****
		MyLists myLists = new MyLists();
		
		myLists.arrayLists();
		System.out.println();
		
		myLists.linkedLists();
		System.out.println();
		
		myLists.stacks();
		System.out.println();
		
		myLists.vectors();
		System.out.println();
		
		
		// **** experiment with sets ****
		MySets mySets = new MySets();
		
		mySets.hashSets();
		System.out.println();
		
		mySets.linkedHashSets();
		System.out.println();
		
		mySets.treeSets();
		System.out.println();
		
		
		// **** experiment with vectors and array lists ****
		MyVectorsAndArrays va = new MyVectorsAndArrays();

		va.vectors();
		System.out.println();
		
		va.arrayLists();
		System.out.println();
		
		
		// **** experiment with Hashtable and ConcurrentHashMap ****
		MyHashTableAndHashMap htm = new MyHashTableAndHashMap();
		
		htm.hashTable();
		System.out.println();
		
		htm.concurrentHashMap();
		System.out.println();
	}

}

Q13. Difference between List and Set in Java?

A list is ordered and allows duplicates. A set is unordered and does not allow duplicate elements.

The code for the class that deals with Lists follows:

Q14. Difference between ArrayList and Vector in Java?

There are many differences, but most important is that an ArrayList is not synchronized and fast while Vector is synchronized and slow. A vector is also a legacy class similar to Hashtable.

The code that deals with Vectors and ArrayList classes follows:

package com.canessa.listsandsets;

import java.util.ArrayList;
import java.util.Iterator;
import java.util.Vector;

/*
 * 
 */
public class MyVectorsAndArrays {

	// **** ****
	final int MAX_ELEMENTS = 13;
	
	// **** constructor ****
	public MyVectorsAndArrays() {
	}

	// **** vectors ****
	public void vectors() {
		
		// **** ****
		Vector&lt;Integer&gt; v = new Vector&lt;Integer&gt;();
		System.out.println("vectors &lt;&lt;&lt; capacity: " + v.capacity());
		
		// **** ****
		for (int i = 0; i &lt; MAX_ELEMENTS; i++) {
			v.add(i);
			System.out.println("vectors &lt;&lt;&lt;        v: " + v.toString());
			System.out.println("vectors &lt;&lt;&lt; capacity: " + v.capacity()); } // **** **** while (v.size() &gt; 0) {
			int x = v.remove(0);
			System.out.println("vectors &lt;&lt;&lt;        x: " + x);
			System.out.println("vectors &lt;&lt;&lt;        v: " + v.toString());
			System.out.println("vectors &lt;&lt;&lt; capacity: " + v.capacity());
		}
	}
	
	// **** array list ****
	public void arrayLists() {
		
		// **** ****
		ArrayList&lt;Integer&gt; al = new ArrayList&lt;Integer&gt;();
		
		// **** ****
		for (int i = 0; i &lt; MAX_ELEMENTS; i++)
			al.add(i);
		
		// **** ****
		System.out.println("arrayLists &lt;&lt;&lt; al: " + al.toString());
		
		// **** ****
		al.remove(4);
		
		// **** ****
		System.out.println("arrayLists &lt;&lt;&lt; al: " + al.toString());
		
		// **** ****
		al.add(4, MAX_ELEMENTS);
	
		// **** ****
		System.out.println("arrayLists &lt;&lt;&lt; al: " + al.toString());

		// **** iterate through the array list ****
		Iterator&lt;Integer&gt; it = al.iterator();
		System.out.print("arrayLists &lt;&lt;&lt; al: [");
		while (it.hasNext()) {
			int i = it.next();
			if (it.hasNext())
				System.out.print(i + ", ");
			else
				System.out.println(i + "]");
		}
	}
}

Q15. Difference between Hashtable and ConcurrentHashMap in Java?

All methods of Hashtable are synchronized which makes them quite slow due to contention if a number of thread increases.

On the other hand, ConcurrentHashMap is specially designed for concurrent use i.e. more than one thread. By default it simultaneously allows 16 threads to read and write from Map without any external synchronization.

ConcurrentHashMap only locks certain portion of the ConcurrentHashMap while Hashtable locks the full Hashtable while iterations.

The code I used to experiment with Hashtable and ConcurrentHashMap classes follows:

package com.canessa.listsandsets;

import java.util.Hashtable;
import java.util.concurrent.ConcurrentHashMap;
import java.util.concurrent.CountDownLatch;

/*
 * 
 */
public class MyHashTableAndHashMap {

	// **** ****
	final int MAX_ELEMENTS = 7;
	
	// **** constructor ****
	public MyHashTableAndHashMap() {
	}

	// **** hash table ****
	public void hashTable() {
		
		// **** ****
		Hashtable&lt;Integer, Integer&gt; ht = new Hashtable&lt;Integer, Integer&gt;();
		
		// **** ****
		CountDownLatch latch = new CountDownLatch(3);

		// **** create and start threads ****
		new Thread(new HashTableThread(ht,    0, 1000, latch)).start();
		new Thread(new HashTableThread(ht, 1000, 2000, latch)).start();
		new Thread(new HashTableThread(ht, 2000, 3000, latch)).start();

		// **** wait for all threads to finish ****
		try {
			latch.await();
		} catch (InterruptedException e) {
			System.err.println("hashTable &lt;&lt;&lt; EXCEPTION " + e.getMessage());
			e.printStackTrace();
		}
		
		// **** ****
		System.out.println("hashTable &lt;&lt;&lt;        ht: " + ht.toString());
		System.out.println("hashTable &lt;&lt;&lt; ht.size(): " + ht.size());
	}
	
	// **** concurrent hash map ****
	public void concurrentHashMap() {
		
		// **** ****
		ConcurrentHashMap&lt;Integer, Integer&gt; chm = new ConcurrentHashMap&lt;Integer, Integer&gt;();
		
		// **** ****
		CountDownLatch latch = new CountDownLatch(3);
		
		// **** create and start threads ****
		new Thread(new HashMapThread(chm,    0, 1000, latch)).start();
		new Thread(new HashMapThread(chm, 1000, 2000, latch)).start();
		new Thread(new HashMapThread(chm, 2000, 3000, latch)).start();
		
		// **** wait for all threads to finish ****
		try {
			latch.await();
		} catch (InterruptedException e) {
			System.err.println("concurrentHashMap &lt;&lt;&lt; EXCEPTION " + e.getMessage());
			e.printStackTrace();
		}
		
		// **** ****
		System.out.println("concurrentHashMap &lt;&lt;&lt;        chm: " + chm.toString());
		System.out.println("concurrentHashMap &lt;&lt;&lt; chm.size(): " + chm.size());
	
	}
}

In order to verify that the Hashtable class supports concurrency a thread was invoked three times with different values as illustrated in this code:

package com.canessa.listsandsets;

import java.util.Hashtable;
import java.util.concurrent.*;

/*
 * 
 */
public class HashTableThread implements Runnable {

	// **** members ****
	Hashtable&lt;Integer, Integer&gt;	ht;
	int 						begin;
	int 						end;
	CountDownLatch 				latch;
	
	// **** constructor ****
	public HashTableThread(Hashtable&lt;Integer, Integer&gt; ht, int begin, int end, CountDownLatch latch) {
		this.ht 	= ht;
		this.begin	= begin;
		this.end	= end;
		this.latch 	= latch;
	}

	// **** ****
	@Override
	public void run() {
		
		// **** do some work ****
		for (int i = begin; i &lt; end; i++) {
			ht.put(i, i * 2);
		}
		
		// **** flag that this thread is done ****
		latch.countDown();
	}
}

A similar implementation for threads was use to verify the operation of the ConcurrentHashMap class:

package com.canessa.listsandsets;

import java.util.concurrent.*;

/*
 * 
 */
public class HashMapThread implements Runnable {

	// **** members ****
	ConcurrentHashMap&lt;Integer, Integer&gt;	ht;
	int 								begin;
	int 								end;
	CountDownLatch 						latch;
	
	// **** constructor ****
	public HashMapThread(ConcurrentHashMap&lt;Integer, Integer&gt; ht, int begin, int end, CountDownLatch latch) {
		this.ht 	= ht;
		this.begin	= begin;
		this.end	= end;
		this.latch 	= latch;
	}

	// **** ****
	@Override
	public void run() {
		
		// **** do some work ****
		for (int i = begin; i &lt; end; i++) {
			ht.put(i, i * 2);
		}
		
		// **** flag that this thread is done ****
		latch.countDown();
	}
	
}
