How can I read wireless signal strength In C++ and Java ?
Please provide a code snippet, a link to a library, or anything else that might show me how to accomplish this?
I want to refer to a static Java variable in my styles.xml, is that possible? Here's a pseudo-xml example:
<style name="Artwork">
<item name="android:background">@drawable/border_{Constants.MY_COLOR}</item>
</style>
I asked a question about Garbage Collection in Java in this topic.
But the answer I got, gave me another question.
Someone mentioned that classes can be collected by the garbage collector to.
Is this true?
And if it is true, how does this work?
By using java reflection, we can easily know if an object is an array. What's the easiest way to tell if an object is a collection(Set,List,Map,Vector...)?
Hi All,
How can I measure the speed of code written in Java?
I planning to develop software which will solve Sudoku using all presently available AI and ML algorithms and compare time against simple brute-force method. I need to measure time of each algorithm, I would like to ask for suggestions on what is the best way of doing that? Very important, program must be useful on any machine regardless to CPU power/memory.
Thank you.
Hi,
I need a Java way to find a running Win process from which I know to name of the executable. I want to look whether it is running right now and I need a way to kill the process if I found it.
Thank you! Greetz, GHad
Here's an excerpt from Sun's Java tutorials:
A switch works with the byte, short, char, and int primitive data types. It also works with enumerated types (discussed in Classes and Inheritance) and a few special classes that "wrap" certain primitive types: Character, Byte, Short, and Integer (discussed in Simple Data Objects ).
There must be a good reason why the long primitive data type is not allowed. Anyone know what it is?

I'm working on an upgrade project and build management is done in Maven 1.0.2. Java version will change to J2SE 5.
Please include in your answer if you have first hand experience on that particular combination (Maven 1.0.2 and J2SE 5)
Thanks

new Class[]{type},
innerProxy);
How can I extract the innerProxy object from proxy?
Hi,
Today I got this question for which I think I answered very bad. I said stream is a data that flows and reader is a technique where we read from that is a static data. I know this is an awful answer, so please provide me the crisp difference and definitions between these two with example in Java.
Thanks.
I write an application in Java. I get form a database a table (clients) which contains fields like:
name | surname | adress
What is the best solution to store this data in my app? Should I create an object for each client and store these objects in a list or set?
The table contains about 100 records and it's already sorted.
Thanks in advance.
Is there any good reason to avoid unused import statements in Java? As I understand it, they are there for the compiler, so lots of unused imports won't have any impacts on the compiled code. Is it just to reduce clutter and to avoid naming conflicts down the line?
(I ask because Eclipse gives a warning about unused imports, which is kind of annoying when I'm developing code because I don't want to remove the imports until I'm pretty sure I'm done designing the class.)
I need to convert XML data to Java objects. What would be best practice to convert this XML data to object?
Idea is to fetch data via a web service (it doesn't use WSDL, just HTTP GET queries, so I cannot use any framework) and answers are in XML. What would be best practice to handle this situation?

Can you do the following with a Java ResourceBundle?
In the properties file...
example.dynamicresource=You currently have {0} accounts.
At runtime...
int accountAcount = 3;
bundle.get("example.dynamicresource",accountCount,param2,...);
To give a result of
"You currently have 3 accounts."
I have a grails app (v 1.1.2) the logging is working fine from the groovy classes, but I can't get it to work from within a java source...
I have a class in package com.mforms.devices., it imports apache log4j, defines the logger as follows
private final org.apache.log4j.Logger loggy = Logger.getLogger(this.getClass());
then refer to it later by doing loggy.error("...")
my Config.groovy has the following
log4j = {
error 'com.mforms'
root {
error 'stdout', 'file'
additivity = true
}
}
What am I doing wrong?!?!
Hi All,
I was just wondering if anyone knew whether the Java Native Access API will locally save the native libraries into a temporary location before or when loading and using native libraries?
We are using Java and Javascript to try to display a huge sheet with freeze panes, but it is being very difficult. Does someone know about a library, method, script or something, either free or commercial, to do this?
Thanks.
Is there a default timeout for threads waiting on a synchronised method in Java? Some threads in my app are not completing as expected. Is there anyway to check whether threads have died as a result of timeouts?
