I have a file which has a many random integers(around a million) each seperated by a white space. I need to find the top 10 most frequently occurring numbers in that file. What is the most efficient way of doing this in java? I can think of 1. Create a hash map, key is the integer from the file and the value is the count. For every numb...
In my Java application I have been passed in a string that looks like this: "\u00a5123" When printing that string into the console, I get the same string as the output (as expected). However, I want to print that out by having the unicode converted into the actual yen symbol (\u00a5 -> yen symbol) - how would I go about doing this? i...
Hi, I am using ASM in order to do bytecode instrumentation for Java programs. What I'm doing is simple - When instrumenting a method, if the instruction is a PUTFIELD, simply do a DUP_X1 right before the instruction, then visit the PUTFIELD and inject a function call with an argument that includes the DUP'ed stack entry. ...
I have a series of concurrent tasks to run. If any one of them fails, I want to interrupt them all and await termination. But assuming none of them fail, I want to wait for all of them to finish. ExecutorCompletionService seems like almost what I want here, but there doesn't appear to be a way to tell if all of my tasks are done, exce...

Hi, I'd like to read the Sun Java Swing tutorials for Java version 5. It's easy to find Sun's tutorials for SDK 6. My searches of Sun's site and using Google didn't turn up any links (yet) to the older tutorial. Even the tutorial link on the SDK 5 page pointed to the current tutorials. Are the older tutorials still available? If so...

When I use some datastore features, I'm getting an error message: Object with id "edvaltt.Teacher@64064b" is managed by a different Object Manager I don't know what this means or how to fix it or where to look for documentation on this error. Can anyone help me? The code I'm using is: @P...
Hi, I have a pretty basic vc++/vs question, but the googles are failing me. I've seen this question posed before, but none of the proposed solutions work for me. I come from a very high-level language background (java/c#), so these pesky linking issues are alien to me. I appreciate your patience... My problem is that when I send my e...
What does the CascadeType.REFRESH actually do? The definition for it is "When we refresh an entity all the entities held in this field refresh too", but what does this mean in practice? Could someone please give me a simple example? ...

EDIT: I'm now sure that the problem is related to the while (true) loop holding all other commands as I've commented it out and the application deploys without the attached exception. I'm not sure how much it is important but my ServletContextListener implementation looks like this: public class BidPushService implements ...
I would like a Java program to have different default settings (verbosity, possibly colored output where supported) depending on its use. In C, there is an isatty() function which will return 1 if a file descriptor is connected to a terminal, and 0 otherwise. Is there an equivalent for this in Java? I haven't seen anything in the JavaDoc...
Hi, I'm looking for a simple way to translate long to String and back in a way that will "hide" the long value. I'd prefer to avoid adding another .jar to the project for this feature. It does not have to be a hard-to-crack encryption, just to look random to the inexperienced eye. Addition: My purpose here is to attach a counter val...

I have a Java app while parses input from a spreadsheet. I've added the ability to run just the parser part standalone from an ant task. However the normal log4j pattern I'm using can make the output hard to read, I'd like to set a simple pattern at runtime. So something like log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd ...
I notice that there is getWebApplicationContext in org.springframework.web.servlet.mvc.AbstractController. This means that spring programmers can use getWebApplicationContext to access beans in the spring IoC container. However, I never see people use this way to get beans in all the spring MVC tutorials. So here comes my question, in ...
With a third party API I observed the following. Instead of using, public static string getString(){ return "Hello World"; } it uses something like public static void getString(String output){ } and I am getting the "output" string assigned. I am curious about the reason of implementing such functionality. What are the advant...
As far as I know, memcached runs in-memory and does not have a persistent backing-store. Currently my team is not ready yet to use memcached. So, I plan to write a simple database backed alternative. My question is pretty much in similar vein to this other question http://stackoverflow.com/questions/33619/concurrent-logins-in-a-web-f...
