Java Execution Time Measurement Library – JETM

Java Execution Time Measurement Library – JETM

The first part of analyzing the applications with bad performance is to identify the code fragments which are causing the issue. In order to identify them, we will need to find out the execution timings across different pieces of the application. ……………

Comparison of Enhancements in Java 1.4, Java 1.5 and Java 6.0

What is Java?

Java is a programming language expressly designed for use in the distributed environment of the Internet. It was designed to have the “look and feel” of the C++ language, but it is simpler to use than C++ and enforces an object-oriented programming model. Java can be used to create complete applications that may run on a single computer or be distributed among servers and clients in a network. It can also be used to build a small application module or applet for use as part of a Web page. Applets make it possible for a Web page user to interact with the page.

The Java Programming Language is a general-purpose, concurrent, strongly typed, class-based object-oriented language. It is normally compiled to the bytecode instruction set and binary format defined in the Java Virtual Machine Specification.

Java Reports – Comparitive Study

One of the important goals that applications must be designed for is to be able to convey complex data to the end-user in the simplest, attractive and most understandable form and ‘Reports and Charts’ go a long way in achieving this goal. Java and JEE applications being one of the leaders in the enterprise application space commonly require to display complex data in the form of Charts (such as Pie charts, bar charts etc), Documents (PDF, MS Excel etc) or Reports that are customized specifically for an application . There are a number of tools available to the Java developer that can be utilized to generate reports. This document covers some of the important aspects of the most commonly used, freely available and Open-Source Reporting tools used in the Java world.

How to handle Memory Leaks in Java/J2EE Applications ?

In this article, I have tried to analyze the various causes which may lead to Memory Exception.

OutOfMemoryException is thrown when there is not sufficient available memory to carry out a requested activity. In this article, I have tried to illustrate the different methods by which memory leaks can be handled in Web Applications.
