Diagnosing Java code: The case for static types Java / Getting Started
Still, static type checking can be one of the key weapons in a powerful arsenal against introducing and for detecting bugs. In this article, Eric Allen makes a case for static type checking, explains why we should be glad that the Java language supports it, and discusses how it can be made even better.
Interfaces in Java Java / General Development
In Java, a class can have at the most one immediate superclass. Multiple inheritance, where a class has more than one superclass, is not allowed in Java. However, one cannot ignore the importance of multiple inheritance because a large number of real-life applications require the use of multiple inheritance. Java provides an alternative approach to support multiple inheritance by introducing a new data type known as interfaces. Although a class cannot inherit multiple classes, it can implement more than one interface.
Reading and Parsing XML Files with Enterprise JavaBeans Java / General Development
In this tutorial you will learn how to read XML files using Java. We will then apply this knowledge to create a Session bean ( EJB ) with ability to read given XML file and return a Java object containing values read from the XML file.
JT-Java Trainer Java / General Development
Java Trainer (JT) is for students who intend to learn Java , C#(or C++ for that matter). It is a simple programming system in a web page (no install), with a language close to C and Java, but cut-down.
Beginner Java Tutorial Java / Getting Started
Java programming language (object-oriented) is developed by Sun Microsystems. Java is a simple, scalable, general purpose object oriented programming language. This is a beginner java tutorial website covering java basics along with java source code.
Java/Introduction to Java Java / Getting Started
This section introduces you with JAVA. Java is an Object Oriented Programming similar to C++ and Smalltalk. But JAVA is platform independent and follows the principle of WORA ( Write Once and Run Anywhere). It is unlike C, C++ which means that you write a JAVA program and compile it only once and run it on any operation system be it Windows, Linux, Solaris etc. If we talk about C++ then it is not all platform independent because needs to be compiled on each operation system in order to execute the program on different operation system. We will discuss this in detail in section Java Virtual Machine that how it achieve such a platform independence where as C, C++, FORTRAN, VB, VC++ and many others.
Taking Screenshots in Java Java / Swing
Have you ever wanted to grab a screenshot from your Java application? Here's a quick tutorial on how to grab a screenshot and save it to a JPEG and PNG file. This shows how to use the Robot class to capture the screen image and the ImageIO API to save it as a JPG and PNG.
The Java Game Development Tutorial Java / Miscellaneous
You should be already able to program in Java, although you don't have to be a expert! The tutorial will give you a very detailed introduction into the development of online games using Java. We will talk about Java Applets because everyone has a Internet browser, so everyone is able to play these games without installing the JDK!.
Weighing in on Java native compilation Java / Getting Started
Java native compilation would surely topple the JVM, taking with it the Java platform's hard-fought platform independence. But even with its growing popularity and the increasing number of native compilers on the market, native compilation has a way to go before it poses a real threat to Java code's portability.
