I have created a game in java and now I just need to add a timer that allow the user to play under 60s. I have searched on internet and found the timer for swing and util packages. could you please just give me a method to be able to use it in my game???
I have a closed source Java application for which vendor has provided APIs for customization. As I have no other documents, i rely completely on the API's javadoc.
I want to trace what methods are actually called in different classes for a particular use case. Is there any way to do that with eclipse?
I have a Java Swing project for my class. I would like put it on my website so people can use it. However I'm not sure if there is a way to turn it into a servlet. Or do I need to know JavaScript? I'm confused. Is there a way to make my swing application into a servlet automatically?
I need to write a custom batch File renamer. I've got the bulk of it done except I can't figure out how to check if a file is already open. I'm just using the java.io.File package and there is a canWrite() method but that doesn't seem to test if the file is in use by another program. Any ideas on how I can make this work?
Are there exists an simple AMPQ server/broker implementation written in Java?
I need it only for local integration tests, starting it from ant/maven, and i don't need any features like a clustering, persistence, performance and so on. Just a fake RabbitMQ-like instance, without installation (just as a dependency at maven pom) and configuration.
Java's jar file format builds off of the zip file format, and supports compression of the class files inside it. When and how does the JVM decide which class files to uncompress and pull out of the jars on its classpath? Is the process dynamic and done at runtime as classes are needed, or are they all uncompressed up front before the program actually runs?
I am just starting with JAVA serialization, I have one exercise to do and I need to lock serialization on any class, it is suppose to throw an exception when I attempt to serialize that class. Does anyone know how to do it?
Thank you
as we "No keyword should be used as an Identifier in java". But there will be some words like asser or enum or any other which have been added as keyword in version 1.4, 1.5 resp. So if any older version code is used to compile with new javac, what happens if that code contains these words as an identifier?
From what time I've spent with threads in Java, I've found these two ways to write threads.
public class ThreadA implements Runnable {
public void run() {
//Code
}
}
//with a "new Thread(threadA).start()" call
public class ThreadB extends Thread {
public ThreadB() {
super("ThreadB");
}
public void run() {
//Code
}
}
//with a "threadB.start()" call
Is there any significant difference in these two blocks of code?
I need to implement a cache solution in java for a cluster of 9 servers with web applications. I saw apache JCS, seems old, do you know another open source solution ?
thanks
Is it possible to reliably determine the compilation time stamp of a given class for both java applications running locally and as applets and/or JNLP webapps ?
When I use the annotation:
@XmlRootElement(name="RootElement", namespace="namespace")
class RootElement {
to create xml file from java, it creates the root element as:
<ns2:RootElement xmlns:ns2="namespace">
but I wanted to create without the "ns2", like:
<RootElement xmlns="namespace">
Any idea how to fix it?

I need encrypt data using exactly the PKCS#1 V2.0 encryption method (defined in item 7.2.1 of the PKCS#1V2 specification).
Is it already implemented for Java?
I'm thinking in something like just pass a parameter to javax.crypto.Cipher specifying "PKCS#1V2", I wonder if there is something like this?
I have a java primitive type at hand:
Class c = int.class; // or long.class, or boolean.class
I'd like to get a 'default value' for this class - specifically the value is assigned to fields of this type if they are not initialized. E.g., '0' for a number, 'false' for a boolean.
Is there a generic way to do this? I tried
c.newInstance()
But I'm getting an InstantiationException, and not a default instance.
