Here you go:

    InputStream is = new ByteArrayInputStream( myString.getBytes() );


**Update** For multi-byte support use (thanks to **Aaron Waibel**&#39;s comment):

    InputStream is = new ByteArrayInputStream(Charset.forName(&quot;UTF-16&quot;).encode(myString).array());

Please see [ByteArrayInputStream][1] manual. 

It is safe to use a charset argument in [String#getBytes(charset)][2] method above.

After JDK 7+ you can use

    java.nio.charset.StandardCharsets.UTF_16

instead of hardcoded encoding string:

    InputStream is = new ByteArrayInputStream(StandardCharsets.UTF_16.encode(myString).array());

  [2]: http://download.oracle.com/javase/1.5.0/docs/api/java/lang/String.html#getBytes%28java.lang.String%29



You could do this:

    InputStream in = new ByteArrayInputStream(string.getBytes(&quot;UTF-8&quot;));

Note the `UTF-8` encoding. You should specify the character set that you want the bytes encoded into. It&#39;s common to choose `UTF-8` if you don&#39;t specifically need anything else. Otherwise if you select nothing you&#39;ll get the default encoding that can vary between systems. From the [JavaDoc][1]:

&gt; The behavior of this method when this string cannot be encoded in the default charset is unspecified. The CharsetEncoder class should be used when more control over the encoding process is required.


  [1]: http://download.oracle.com/javase/6/docs/api/java/lang/String.html#getBytes%28%29

    InputStream in = new ByteArrayInputStream(yourstring.getBytes());

**Java 7+**

It&#39;s possible to take advantage of the `StandardCharsets` JDK class:

    String str=...
    InputStream is = new ByteArrayInputStream(StandardCharsets.UTF_16.encode(str).array());

Beginning with Java 7, you can use the following idiom:

    String someString = &quot;...&quot;;
    InputStream is = new ByteArrayInputStream( someString.getBytes(StandardCharsets.UTF_8) );
        

Instead of CharSet.forName, using com.google.common.base.Charsets from Google&#39;s Guava (http://code.google.com/p/guava-libraries/wiki/StringsExplained#Charsets) is is slightly nicer:

    InputStream is = new ByteArrayInputStream( myString.getBytes(Charsets.UTF_8) );

Which CharSet you use depends entirely on what you&#39;re going to do with the InputStream, of course.

In Scala, is there any difference at all between `Nil` and `List()`?

If not, which one is more idiomatic Scala style? Both for creating new empty lists and pattern matching on empty lists.

Scala: Nil vs List()

I&#39;m using CMake to build my project. I have added a unit test binary which is using the Boost unit testing framework. This one binary contains all of the unit tests. I&#39;ve added that binary to be run by CTest:

    ADD_EXECUTABLE( tftest test-main.cpp )
    ENABLE_TESTING()
    ADD_TEST( UnitTests tftest)

But the build output in Visual Studio only shows the result of running CTest:

          Start 1: UnitTests
      1/1 Test #1: UnitTests ................***Failed    0.05 sec

      0% tests passed, 1 tests failed out of 1

This is not very helpful, because I can&#39;t see which test failed. If I run ctest manually from the command line with `--verbose` I get the output from a Boost unit test which tells what actually failed:

    1: Test command: tftest.exe
    1: Test timeout computed to be: 9.99988e+006
    1: Running 4 test cases...
    1: test-main.cpp(20): error in &quot;sanity_check3&quot;: check 1 == 2 failed
    1:
    1: *** 1 failure detected in test suite &quot;Master Test Suite&quot;
    1/1 Test #1: UnitTests ................***Failed    0.00 sec

So, what do I need to change in the CMakeLists.txt to have CTest run with `--verbose` at all times? Is there a better way to use Boost unit tests with CMake/CTest?

A service class has a `@GET` operation that accepts multiple parameters. These parameters are passed in as query parameters to the `@GET` service call.

	@GET
	@Path(&quot;find&quot;)
	@Produces(MediaType.APPLICATION_XML)
	public FindResponse find(@QueryParam(&quot;prop1&quot;) String prop1, 
                             @QueryParam(&quot;prop2&quot;) String prop2, 
                             @QueryParam(&quot;prop3&quot;) String prop3, 
                             @QueryParam(&quot;prop4&quot;) String prop4, ...) 

The list of these parameters are growing, so I would like to place them into a single bean that contains all these parameters.

    @GET
    @Path(&quot;find&quot;)
    @Produces(MediaType.APPLICATION_XML)
    public FindResponse find(ParameterBean paramBean) 
    {
        String prop1 = paramBean.getProp1();
        String prop2 = paramBean.getProp2();
        String prop3 = paramBean.getProp3();
        String prop4 = paramBean.getProp4();
    }

How would you do this?  Is this even possible?

I have a multi-module maven project. We intend to version all these modules together. But as of now I am ending up hard-coding version in each of the module pom.xml as below

&lt;!-- language-all: lang-xml --&gt;

    &lt;parent&gt;
		&lt;artifactId&gt;xyz-application&lt;/artifactId&gt;

	&lt;artifactId&gt;xyz-Library&lt;/artifactId&gt;
	&lt;version&gt;2.50.0.g&lt;/version&gt;
 
and the main parent module has the below configuration

    &lt;modelVersion&gt;4.0.0&lt;/modelVersion&gt;

I have a list of objects and I need to save that somewhere in my computer. I have read some forums and I know that the object has to be `Serializable`. But it would be nice if I can get an example. For example if I have the following:

    [Serializable]
    public class SomeClass
    {
         public string someProperty { get; set; }
    }

    SomeClass object1 = new SomeClass { someProperty = &quot;someString&quot; };
    
But how can I store `object1` somewhere in my computer and later retrieve?

Say I have a function, for example the old favourite

    def factorial(n:Int) = (BigInt(1) /: (1 to n)) (_*_)

Now I want to find the biggest value of `n` for which `factorial(n)` fits in a Long. I could do 

    (1 to 100) takeWhile (factorial(_) &lt;= Long.MaxValue) last

This works, but the 100 is an arbitrary large number; what I really want on the left hand side is an infinite stream that keeps generating higher numbers until the `takeWhile` condition is met.

I&#39;ve come up with 

    val s = Stream.continually(1).zipWithIndex.map(p =&gt; p._1 + p._2)

but is there a better way?

(I&#39;m also aware I could get a solution recursively but that&#39;s not what I&#39;m looking for.)

Infinite streams in Scala

Let&#39;s say I have the following WCF implementation:

    public Stream Download(string path)
    {
        FileStream stream = new FileStream(path, FileMode.Open, FileAccess.Read);
        return stream;
    }

Who&#39;s responsible for disposing the returned value? After all, a network failure might occur, hence the consumer might not be able to dispose it.

Stream as a return value in WCF - who disposes it?

The (now defunct) page http://stream.twitter.com/1/statuses/sample.json used to return a continuous and endless stream of JSON data.

I&#39;d like to process it using jQuery (or JavaScript, but preferably jQuery) inside my own web page to be able to display visual effects based on the live feed of tweets.

Since as far as I know the jQuery `parseJSON` function will only execute the callback function after all the data has been sent by the server, but this is actually a continuous stream of data. How can I process the data &quot;as it happens&quot; but still keep the connection running?

Process a continuous stream of JSON

I have a program that frequently uses an external program and reads its outputs.
It works pretty well using your usual process redirect output, but one specific argument for some reason hangs when I try to read it, no error message - no exception, it just &#39;stops&#39; when it reaches that line.
I of course use a centralized function to call and read output from the program, which is this:

    public string ADBShell(string adbInput)
    {
        try
        {
            //Create Empty values
            string result = string.Empty;
            string error = string.Empty;
            string output = string.Empty;
            System.Diagnostics.ProcessStartInfo procStartInfo 
                = new System.Diagnostics.ProcessStartInfo(toolPath + &quot;adb.exe&quot;);

            procStartInfo.Arguments = adbInput;
            procStartInfo.RedirectStandardOutput = true;
            procStartInfo.RedirectStandardError = true;
            procStartInfo.UseShellExecute = false;
            procStartInfo.CreateNoWindow = true;
            procStartInfo.WorkingDirectory = toolPath;
            System.Diagnostics.Process proc = new System.Diagnostics.Process();
            proc.StartInfo = procStartInfo;
            proc.Start();
            // Get the output into a string
            proc.WaitForExit();
            result = proc.StandardOutput.ReadToEnd();
            error = proc.StandardError.ReadToEnd();  //Some ADB outputs use this
            if (result.Length &gt; 1)
            {
                output += result;
            }
            if (error.Length &gt; 1)
            {
                output += error;
            }
            Return output;
        }
        catch (Exception objException)
        {
            throw objException;
        }
    }
The line that hangs is `result = proc.StandardOutput.ReadToEnd();`, but again, not every time, only when sent a specific argument (&quot;start-server&quot;). All other arguments work just fine - it reads the value and returns it.
It&#39;s also strange the way it hangs. It doesn&#39;t freeze or give an error or anything, it just stops processing. As if it was a &#39;return&#39; command, except it doesn&#39;t even return to the calling function, it just stops everything with the interface still up and running.
Anyone experienced this before? Anyone have any idea what I should try? I&#39;m assuming it&#39;s something unexpected within the stream itself, but is there a way I can handle/ignore this so that it reads it anyway?
