371. The continuing Revolution of java
By: aathishankaran : 2007-02-01
Description: The initial release of java was nothing short of revolutionary, but it did not mark the end of java's era of rapid innovation. Unlike most other software systems that usually settle into a pattern of small, incremental improvements, java continued to evolve at an explosive ace. Soon after the release of java1.0, the designers of java had already created java1.1. The features added by java 1.1 were more significant and substantial than the increase in the minor revision number would have you think. Java 1.1 added many new library elements, redefined the way events are handled by applets, and reconfigured may features of the 1.0 library. It also deprecated (rendered obsolete) several features originally defined by java 1.0. Thus, java 1.1 both added and subtracted attributes from its original specification.
372. Polymorphism, Encapsulation, and Inheritance work together
By: aathishankaran : 2007-02-01
Description: When properly applied, polymorphism, encapsulation, and inheritance combine to produce a programming environment that supports the development of far more robust and scalable programs than does the process-oriented model. A well-designed hierarchy of classes is the basis for reusing the code in which you have invested time and effort developing and testing. Encapsulation allows you to migrate your implementations over time without breaking the code that depends on the public interface of your classes. Polymorphism allows you to create clean, sensible, readable, and resilient code.

379. Read from a COM port using Java program
By: Steven Lim : 2006-12-11
Description: Most projects that deal with hardware and devices, needs to communicate with them using the COM port of the PC or Server. For example if there is a modem that is connected to a server via its COM port and the Java program has to read the output of the modem then the Java program has to read the COM port for any incoming data.
380. Connect to a password protected URL from Java program
By: Mike Cooper : 2006-12-11
Description: It is quite common for a Java program to connect to an URL and process its data or post data to it. Some URLs are password protected and can be connected to it only with a username and password. While manually accessing such sites, the browser will popup a login screen automatically for the user to key in username and password. But if you are connecting from a Java program then how can you do this login programmatically.
