I am asking because if it is not, it can be abused as synchronizations mechanism. I am asking about Java.

This code should produce even and uneven output because there is no synchronized on any methods. Yet the output on my JVM is always even. I am really confused as this ... |

Is the non-blocking Java NIO still slower than your standard thread per connection asynchronous socket?
In addition, if you were to use threads per connection, would you just create new threads or ... |
I'm moving from C# to Java, and I need to implement a set of asynchronous tasks.
I have a good knowledge of Java threading, but I liked .NET's BeginInvoke and EndInvoke methods ... |
This is probably a very generic question but I will shoot anyway since I need honest advice. I have a very simple library which is mostly threadsafe due to most clases ... |
I have a scientific application which I usually run in parallel with xargs, but this scheme incurs repeated JVM start costs and neglects cached file I/O and the JIT compiler. ... |
I have just started working on a airline booking website where I request various 'providers' to provide flight data(duration, price, timings etc) based on the user's search parameters.
I would send ... |

Hi, I'm a rookie on the thread world, so please forgive me if its a silly question Let's say I have a web application (servlets/ejbs) with one functionality is to print huge reports. Each report take time to be constructed and to be printed. I don't want my client to be bound to the construct and print object. Instead of waiting ... |
Hi, I have a xml file and would like to read data from the xml file every 10 seconds. I want to run this process once in every 10 seconds as this file is updated freqently. please note that the daemon thread which reads the xml data should run continously for ever. Can I implement the process using java.util.Timer? Any sample ... |
Hi I am confused about asynchronous threading concept. If the synchronous thread is like a line which is divided at certain point to two lines of excution say a main and Thread-1. Then asynchronous thread will be like the above but Thread-1 line end is attached to the main thread line, i.e. it looks like a line and a circle on ... |
What is the correct pattern to use for user feedback when a service thread fails? Does each asynchronous sub thread typically throw the exceptions up or does one apply listeners? Take my example: I have a user interface which on an asynchronous thread creates a new multi cast connection, and then listens to the connection for incoming messages. The multi cast ... |
Sir, I'am reading multithreading and am unable to understand this point.it says "java uses threads to enable the environment to be asynchronous". this is quite contrary to what i basically understood. well the other term for threads is concurrency. any program is asynchronous. where each part of the code oocurs at different times or in a sequence. the only advantage is ... |
This is from:JAVA threads by orielly: 3.2 Reading Data Asynchronously Let's look at a complete example. One of the primary uses for threads within a Java program is to read data asynchronously. In this section, we'll develop a class to read a network socket asynchronously. Why is threading important for I/O? Whether you are reading from or writing to a file ... |
