You need to specify the minimum width of the field.

    String.format(&quot;%&quot; + numberOfSpaces + &quot;s&quot;, &quot;&quot;); 

Why do you want to generate a String of spaces of a certain length.

If you want a column of this length with values then you can do:

    String.format(&quot;%&quot; + numberOfSpaces + &quot;s&quot;, &quot;Hello&quot;); 

which gives you numberOfSpaces-5 spaces followed by Hello. If you want Hello to appear on the left then add a minus sign in before numberOfSpaces.

    int numberOfSpaces = 3;
    String space = String.format(&quot;%&quot;+ numberOfSpaces +&quot;s&quot;, &quot; &quot;);

How to get difference between two dates in Year/Month/Week/Day in an efficient way?

eg. difference between two dates is 1 Year, 2 Months, 3 Weeks, 4 Days.

Difference represents count of year(s), month(s), week(s) and day(s) between two dates.

I have this library called [BASS][1] which is an audio library which I&#39;m going to use to record with the microphone. I have all the files needed to use it, but I don&#39;t know how to install the library. I tried taking the example files and putting them in the same directory as the bass.h file. But I got a bunch of errors saying there are function calls that doesn&#39;t exist. 

So my question is, how do I install it to be able to use it?

how I can rewrite this:

    for (int i = 0; i &lt; numberOfSpaces; i++) {
        System.out.print(&quot; &quot;);
    }

using `String.format()`?

I&#39;m pretty sure that this is possible but the [javadoc is a bit confusing][1].

How do I convert `int[]` into `List&lt;Integer&gt;` in Java?

Of course, I&#39;m interested in any other answer than doing it in a loop, item by item. But if there&#39;s no other answer, I&#39;ll pick that one as the best to show the fact that this functionality is not part of Java.

I have two user Objects and while I try to save the object using 

    session.save(userObj);

I am getting the following error:

    Caused by: org.hibernate.NonUniqueObjectException: a different object with the same identifier value was already associated with the session:
    [com.pojo.rtrequests.User#com.pojo.rtrequests.User@d079b40b]

I am creating the session using 

    BaseHibernateDAO dao = new BaseHibernateDAO(); 			

    rtsession = dao.getSession(userData.getRegion(),
                               BaseHibernateDAO.RTREQUESTS_DATABASE_NAME);

    rttrans = rtsession.beginTransaction();
    rttrans.begin();
    
    rtsession.save(userObj1);
    rtsession.save(userObj2);
    
    rtsession.flush();
    rttrans.commit();
    
    rtsession.close(); // in finally block

I also tried doing the `session.clear()` before saving, still no luck.

This is for the first I am getting the session object when a user request comes, so I am getting why is saying that object is present in session.

Any suggestions?

I want to add the oracle jdbc driver to my project as dependency (runtime scope) - ojdbc14.
In MVNrepository site the dependency to put in the POM is:

&lt;!-- language: xml --&gt;

    &lt;dependency&gt;
        &lt;groupId&gt;com.oracle&lt;/groupId&gt;
        &lt;artifactId&gt;ojdbc14&lt;/artifactId&gt;
        &lt;version&gt;10.2.0.3.0&lt;/version&gt;
    &lt;/dependency&gt;

of course this does&#39;t work as it is not in the central repository used by maven.
2 questions:

1. How do I find a repository (if any) that contains this artifact?

2. How do I add it so that Maven will use it?

I can write an assertion message one of two ways.  Stating success:

    assertEquals( &quot;objects should be identical&quot;, expected, actual );

Or stating the condition of being broken:

    assertEquals( &quot;objects aren&#39;t identical&quot;, expected, actual );

Is there a standard for this in JUnit specifically?  If not, what are the arguments for each side?

P.S. I&#39;ve seen articles on the web demonstrating both of these without explanation, so just saying &quot;search Google&quot; is not an answer!

**[UPDATE]**

Everyone is getting hung up on the fact that I used `assertEquals` and therefore the message is probably useless.  But of course that&#39;s just because I wanted to illustrate the question simply.

So imagine instead it&#39;s:

    assertTrue( ... big long multi-line expression ... );

Where a message is useful.

Should the JUnit message state the condition of success or failure?

I am trying to create an array of strings in C.  If I use this code:

    char (*a[2])[14];
    a[0]=&quot;blah&quot;;
    a[1]=&quot;hmm&quot;;

gcc gives me &quot;warning: assignment from incompatible pointer type&quot;.  What is the correct way to do this?

edit: I am curious why this should give a compiler warning since if I do `printf(a[1]);`, it correctly prints &quot;hmm&quot;.

The Javadoc about [`String.intern()`][1] doesn&#39;t give much detail. (In a nutshell: It returns a canonical representation of the string, allowing interned strings to be compared using `==`)

* When would I use this function in favor to `String.equals()`?
* Are there side effects not mentioned in the Javadoc, i.e. more or less optimization by the JIT compiler?
* Are there further uses of `String.intern()`?

How do you get the text of a `TextView` to be Justified (with text flush on the left- and right- hand sides)?

I&#39;ve seen that some PHP functions are commented at the top, using a format that is unknown to me:

    /**
     *
     * Convert an object to an array
     *
     * @param    object  $object The object to convert
     * @return      array
     *
     */

My IDE gives me a dropdown selection for the things such as @param and @return, so it must be documented somewhere. I&#39;ve tried searching google but it won&#39;t include the @ symbol in its search.

What is this format of commenting and where can I find some information on it?

Is there a simple way to convert one date format into another date format in PHP?

I have this:

    $old_date = date(&#39;y-m-d-h-i-s&#39;);            // works

    $middle = strtotime($old_date);             // returns bool(false)
    
    $new_date = date(&#39;Y-m-d H:i:s&#39;, $middle);   // returns 1970-01-01 00:00:00

But I&#39;d of course like it to return a current date rather than the crack &#39;o dawn. What am I doing wrong?
