  Use Memory Analyzer Tool in Eclipse


When developing applications, we often encounter memory issues of an application. To analyze how much memory each class takes, we need to have some specific tools to assist us. One of them is Memory Analyzer Tool on Eclipse. The Eclipse Memory Analyzer is a fast and feature-rich Java heap analyzer that helps you find memory leaks and reduce memory consumption. To use the Memory Analyzer Tool, you first need to install it on Eclipse. You can go to Help -> Install New Software.... Paste  h...

  Haxe: Another multiplatform language


There are two kinds of programmers: One is using different languages to solve problems, the other is inventing languages to solve problems. Haxe is an emerging open source programming language which is universal, powerful and easy-to-use. Some languages claimed they were multiplatform languages, such as Java, C# and ActionScript. They all are based on some platforms, Java has JVM, C# has .Net and ActionScript has Flash Player. While Haxe is a trule multiplatform language, it can be used to devel...

  Are frameworks making developers dumb?


Last week I got to take interviews to hire senior java developers with around 5 years of experience. But after the interview process is over I felt like the frameworks makes developers life easier but at the same time making them dumb.Everyone puts almost all the new frameworks on their resume claiming they have "Strong, working experience on Spring, Hibernate, Web Services etc".Here is how the interviews went on.Me: You have used Spring in your latest project. What are the advant...

  Command Line Arguments


Our Hello program still isn’t very general. We can’t change the name we say hello to without editing and recompiling the source code. This may be fine for the programmers, but what if the secretaries want their computers to say Hello to them? (I know. This is a little far-fetched but bear with me. I’m making a point.)What we need is a way to change the name at runtime rather than at compile time. (Runtime is when we type java HelloRusty. Compile time is when we type jav...

  Difference between Enumeration and Iterator in java interview question and answer


This tutorial explains about what are the differences between Iterators and Enumeration and similarity of both interface which may be asked in a core java interview. Functionalities of both Iterator & Enumeration interfaces are similar that means both generates a series of all elements of the object which is to have its values iterated that can be traversed one at a time using next() method incase of Iterator and nextElement() method incase of Enumeration. The more powe...

  Why 0.1+0.2 != 0.3


In programming languages such as JavaScript, c/c++, Java and Matlab, you will find that you will get unexpected result when doing float point calculation. For example, when calculating 0.1 + 0.1, you will not get 0.3: > 0.1 + 0.2 == 0.3 false > 0.1 + 0.2 0.30000000000000004 Don't be surprised of this result, this is the end result of IEEE 754 standard, float point number cannot be accurately represented according to IEEE 754 because: No enough memory is allocated for representing the num...

  TIOBE : No news today


TIOBE released the programming index for September 2012. There is no big change for this month compared to last month, the top 3 are still C, Java and Objective-C. In top 20, only Transact-SQL exchanged the position with VB.NET. Java shows trend of drop, will it be worse because of the ignorance of Java's vulnerabilities by Oracle. This index shows that the programing lnaguage market is quite normal, no big events. Except Objective-C, in recent years there are no other new languages which have b...

  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...

  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 easier than learning Java! There...
