  C++ 11 Memory Management

Enterprise development and networking specialist Stephen B. Morris illustrates how to handle a classic C/C++ problem by using the new features in C++ 11 in conjunction with more established techniques.Memory management has always been one of the most error-prone areas of C++. The same is true of C. One of the strengths of managed languages, such as Java and C#, is their support for automatic garbage collection. Garbage collection still isn't a feature of C++ 11, so we must still be caref...

  Address of a Java Object

In conventional java programming, you will never need address or location of a java object from memory. When you discuss about this in forums, the first question raised is why do you need to know the address of a java object? Its a valid question. But always, we reserve the right to experiment. Nothing is wrong in exploring uncharted areas.I thought of experimenting using a little known class from sun package. Unsafe is a class that belongs to sun.misc package. For some of you the package might ...

  Stream API in Java 8

Overview In this lesson on Stream API in Java, we will study how we can put Streams to use to write efficient and much more maintainable code. We will also write code with and without Streams so that we are able to compare the two versions. Before doing all this, we must know how to create a Stream and process it and that is what we will get started with. Introduction to Streams We will be starting with creating Streams. Let us get started with the Stream<T> API which enables us to play w...

  Benefits and Drawback of a Layered Architecture

Most enterprises today are application centric. But the problem with the application is that their database schemas, user interfaces, programming interfaces and object models are tightly coupled and difficult to change. If you want to add a new field to a database table and you’re lucky, the change will reflect through the entire system. But often the change needs to be replicated manually across the entire system. And as applications are difficult to change, adding business rules or proce...

  Language Complexity?

Some languages are complex, others are simple … right?  C++ versus just about anything else is a good example here.  But, it begs the question: what makes a language complex? So, I’ve just been reading Bruce Eckel’s Artima article on Scala.  It’s actually a nice article, and I enjoyed it.  But, one thing bugged me — and, it’s nicely summarised in this quote: But you can see from the code above that learning Scala should be a lot eas...

  Moving from Java to C++: An Interview with Rogers Cadenhead

In this interview, co-author of Sams Teach Yourself C++ in 24 Hours, 5th Edition Rogers Cadenhead discusses moving from Java to C++, what brought him to C++, and the best tactics for learning C++.Danny Kalev: For how long were you a Java programmer? Can you tell us a bit about the nature of the projects in which you took part at that time?Rogers Cadenhead: I've been a Java programmer since the language was launched by Sun Microsystems in 1995. I was doing website develop...

  try { return } finally {}

Do you know what value will be printed when following program is ran? class Test { public int aaa() { int x = 1; try { return ++x; } catch (Exception e) { } finally { ++x; } return x; } public static void main(String[] args) { Test t = new Test(); int y = t.aaa(); System.out.println(y); } } And before answering the above question, do you have answers to following questions? If ther...

  Why I love Common Lisp and hate Java

“Common what?” is a common reply I get when I mention Common Lisp. Perhaps rightly so, since Common Lisp is not all that common these days. Developed in the sixties, it is one of the oldest programming languages out there. In its heydays it was used mostly for Artificial Intelligence research at MIT, Stanford, Carnegie Mellon and the like, and therefore has a lingering association with AI. People not in AI shy away from Lisp. Common Lisp is a powerful and versatile program...

  Java Doesn't Need to Be So Bad

I do a lot of Java coding and I enjoy it. I admit that there is a lot of typing, often a lot of boilerplate and getting even simple tasks done can involve too much work. Most of the tools that try to fix these problems trade one moment saved for another lost. Maven's XML based configuration file is a good example: Thank you for making my project easier to manage and I won't forget that you made me edit XML to do so. These are the things that you live with, these are the things you trade for ...

  Java Concurrency Basics: CountDownLatch and CyclicBarrier

CountDownLatch CountDownLatch can be used in synchronizing behavior among threads, it makes one or more threads wait for some actions in other threads to be completed. It has a property count which defines how many countDown() need to be called before other threads which called await() to be waked up.  When a thread calls CountDownLatch.await(), the thread will be blocked until the value of count becomes 0. The initial value of count can be specified when creating the CountDownLatch instanc...
