JAVA: September 2008
http://java89.blogspot.com/2008_09_01_archive.html
Saturday, September 13, 2008. A Java Virtual Machine (JVM) is a set of computer software programs and data structures which use a virtual machine model for the execution of other computer programs and scripts. The model used by a JVM accepts a form of computer intermediate language commonly referred to as Java bytecode. This language conceptually represents the instruction set of a stack-oriented, capability architecture. The JVM runtime executes .class or .jar files, emulating the JVM instructio...The J...

JAVA: August 2008
http://java89.blogspot.com/2008_08_01_archive.html
Sunday, August 31, 2008. JAVA AND C SHARP COMPARISON. Both C# and Java are designed from the ground up as VMT-based object oriented languages, with a syntax similar to C . (C in turn is derived from C.) Neither language is a superset of C or C , however. Both use garbage collection as a means of reclaiming memory resources, rather than explicit deallocation of memory. Both include thread synchronization mechanisms as part of their language syntax. Links to this post. Thursday, August 28, 2008.

JAVA: October 2008
http://java89.blogspot.com/2008_10_01_archive.html
Tuesday, October 7, 2008. Mainframes (often colloquially referred to as Big Iron are computers used mainly by large organizations for critical applications, typically bulk data processing such as census, industry and consumer statistics, ERP, and financial transaction processing. The term probably originated from the early mainframes, as they were housed in enormous, room-sized metal boxes or frames. Later the term was used to distinguish high-end commercial machines from less powerful units. Modern main...

computer program: June 2008
http://computerprogram89.blogspot.com/2008_06_01_archive.html
Saturday, June 7, 2008. Computer programs (also software programs, or just programs) are instructions for a computer. A computer requires programs to function, and a computer program does nothing unless its instructions are executed by a central processor. Computer programs are either executable programs or the source code from which executable programs are derived (e.g., compiled). The form in which a program is created may be textual or visual. In a visual language program, elements are graphically...

JAVA: JAVA IDE
http://java89.blogspot.com/2008/10/java-ide.html
Tuesday, October 7, 2008. A Java IDE (Integrated Development Environment) is a software which enables the users to write and debug Java programmes easily. Some of them highlights keywords, some have popup menus for methods and attributes and thus help the users to do the stuff easily. JCreator is a simple and light weight JAVA IDE - it runs only on Windows platforms. It is very easy to install and starts quickly, as it is a native application. This is a good choice for beginners. Among Other JAVA IDEs are.

JAVA: JAVA PROGRAMMING REFLECTION
http://java89.blogspot.com/2008/10/java-programming-reflection.html
Tuesday, October 7, 2008. Reflection is a new concept in Java, and did not exist in classical compiled languages like C, and C . The idea is to discover an object's attributes and its methods progrematically. You can use these reflection objects to access fields, invoke methods, or instantiate instances, all without having compile time dependencies on those features. The Java runtime provides the corresponding classes for reflection. Most of the Java classes which support reflection are in the ja...Refle...

JAVA: JPHTHON
http://java89.blogspot.com/2008/10/jphthon.html
Tuesday, October 7, 2008. Jython, successor of JPython, is an implementation of the Python programming language written in java. Jython also includes jythonc, a compiler that converts Python source code into Java bytecode. This allows Python programmers to write classes which can be fully utilized by a Java program. Developments are going steady and an alpha version of the corresponding Jython 2.5 release has been available since July 2008. Jython is one of two scripting languages (with Jacl) used in Web...

JAVA: JAVA PROGRAMMING/EXCEPTIONS
http://java89.blogspot.com/2008/10/java-programmingexceptions.html
Tuesday, October 7, 2008. In Java, there are two main flow of code executions. Normal main sequential code execution, the program doing what it meant to accomplish. Exception handling code execution, the main program flow was interrupted by an error or some other condition that prevent the continuation of the normal main sequential code execution. A thrown exception object can be caught by the catch keyword and specifying the exception object's class or its super-class. Subscribe to: Post Comments (Atom).
