Filsystem. Java Threads Tutorial Java Tutor J2EE Training Web Services Axis EJB Design patterns UML Personal Threads. Introduction Thread: A thread is a line of execution of code. Lets understand what is a line of execution of code. A Java program when executed has at least one thread called main thread. The main thread executes the code in the public static void main method of the java program. The execution of lines of code in the main method in a step by step way, by the main thread is in other words the line of execution of code. JVM creates the main thread. The main thread executes the code in the main method(public static void main(String args[])).

Using Thread Class Subclass the Thread class. At times we need threads in Single Processor(with single core) machines too. Tutorial: Java Collections - CodeCall Programming Forum. Collections Collections are an interface in the java.util package, and as its name suggests, it is used to define a collection of objects. There are many different classes which implement the collections interface. Each one has its unique features, some add elements in a sorted manner, others in a binary fashion.

But there are two basic structures, a map and a list and most others extended these interfaces. Here is how you do it 1) Declare any object you wish to insert into a Map. Now note that a map stores value in a <KEY><VALUE> pair. Say we want to store an object of DummyClass DummyClass1 dm2 = new DummyClass1(); 2) Now you declare a HashMap which will store the key value pair. Map m = new HashMap(); //Old method Map<DummyClass> m = new HashMap<DummyClass>(); //New method as per Java 1.5 and above 3) To add the object to a map you need to use the put function.

M.put("KEY1", dm1); 4) To retrieve this object use the get method and use KEY1 to identify the object to retrieve it. Code Output. Top 10 things that annoy programmers | delimitdesign.com.

In this case, let's call out to Jim Weaver's JavaFX Calculator demo: Here we go, here's all that's needed, via the Scripting API, which is included in the JavaFX SDK: 01.package calc; 03.import java.io.InputStreamReader; 04.import javax.script.ScriptEngine; 05.import javax.script.ScriptEngineManager; 06.import javax.script.ScriptException; 08.public class CalculatorLauncher { 10. public static void main(String[] args) { 11. try { 12. 13. 14. 15. engine.eval(reader); 16. } catch (ScriptException ex) { And so, here's my whole application, calling Jim Weaver's Calculator demo: Nice.

Guice - Chart Porn: Create Your Own Original Star Trek Story. OOP Spelprogrammering. Dataspel Många dataspel kan liknas vid simuleringar av en verklig eller påhittad värld. T.ex bilspel, äventyrsspel, eller spel som SimCity och Sims. Simulera betyder efterlikna. Följande är typiskt för spel-liknande simuleringar: Det finns en värld med objekt Det finns ett tidsflöde (realtid, nedsaktad tid, uppsnabbad tid) Objekten i världen är aktiva och kan ha varierande grad av AI Världen visualiseras på bildskärmen Spelaren kan interagera med objekten i världen på olika sätt Spelprogrammering Centrala delar i ett spelprogram: Grafik ("Sprites") Uppdateringsloop (Timer) Inmatning (mus och tangentbord) Nedan diskuteras dessa.

Sprite-animeringar Sprite betyder "älva". Sprites i Java Det finns två grundläggande sätt att programmera sprites i Java: Som komponenter i ett fönster (där spriteklasserna är subklasser till t.ex JComponent eller JLabel) Som egna objekt som ritas upp i via paintComponent.

Navigation: Språket Nu har vi lekt runt lite med applets och ritat lite enkla saker. Klasser Nu har jag nämnt ordet klasser ganska många gånger, och du har troligtvis inte så bra koll på vad det är ändå. Metoder Vi har även skrivit ett par metoder. Datatyper En datatyp är en typ utav data. Returvärden Nu ska vi tillbaka till metoderna en liten stund. Konkreta tillämpningar Nu har jag svammlat massor om datatyper, variabler, objekt och så vidare. Så kan en mycket enkel klass se ut. Nu ska jag visa hur man gör ett objekt utav en klass. public class HuvudKlass { public void HuvudKlass() { NyKlass Objekt = new NyKlass();}}public class NyKlass {} Nu uppstår ju en annan intressant fråga.

15 Exercises for Learning a new Programming Language. By: Prashant N Mhatre I’ve working knowledge of a bunch of programming languages but job demands to learn a new language frequently in a short time. Instead of reading hundreds manual/book pages, I quickly read 10-15 pages of tutorial or primer. (As you know google is the best search engine to look for such stuff). I keep printed copy of the language syntax reference card handy. (There are many reference cards available over internet. Type in ’language to learn’ + ’reference card’ in google.) First of all, get familiar with Compiler, compiler option, editor shortcuts or integrated development environment (IDE).

To grasp basics of a new language quickly, here are the exercises I use. . (1) Display series of numbers (1,2,3,4, 5....etc) in an infinite loop. . (2) Fibonacci series, swapping two variables, finding maximum/minimum among a list of numbers. (3) Accepting series of numbers, strings from keyboard and sorting them ascending, descending order. While running the program give value mu = 0. Java Methods: PowerPoints. Lesson: Object-Oriented Programming Concepts (The Java™ Tutorials > Learning the Java Language)

If you've never used an object-oriented programming language before, you'll need to learn a few basic concepts before you can begin writing any code. This lesson will introduce you to objects, classes, inheritance, interfaces, and packages. Each discussion focuses on how these concepts relate to the real world, while simultaneously providing an introduction to the syntax of the Java programming language. What Is an Object? An object is a software bundle of related state and behavior. What Is a Class? A class is a blueprint or prototype from which objects are created. What Is Inheritance? Inheritance provides a powerful and natural mechanism for organizing and structuring your software.

What Is an Interface? An interface is a contract between a class and the outside world. What Is a Package? A package is a namespace for organizing classes and interfaces in a logical manner.

Several whitespace users have sent in their contributions as examples of use of the language. Please get in touch if you have a program that you'd like to be added to this list. Multi language Written by Jeremy James, this program is both valid whitespace and valid C, and does approximately the same no matter which language you choose to execute it in.

A practical use for whitespace might be to embed this in a rot13ed text file. Written by Chris Morris. Quine Every language needs to have a quine, which is a program that outputs its own source code.
