As you may have worked out, it&#39;s not necessary to specify the `l` flag. According to [the docs][1], a decimal integer is specified by `d` just like in C++.  So the answer is just `%d`.

Use `%d` for decimals (long, int).  It works OK.  E.g.: 

    System.err.println(String.format(&quot;%d&quot;, 193874120937489387L));

...will print just fine.  Read up on [`java.util.Formatter`][1] for more details.  `%d` will take a `long`, no problem.

I often have to design XML schemas for different XML-bases import routines. It is clear that XML schemas will evolve over time or they could contain bugs to be fixed, so it is important to capture the schema&#39;s version and to have some mechanism to bind against a specific version.

Currently I have two scenarios:

 1. The bug is found within the schema and all schema instances must comply with the fixed version.

 2. The schema upgraded and should be considered as preferable but an old one should be also supported.

Finally I came up with storing version information within the namespace of schema:

    targetNamespace=&quot;http://schemas.company.com/Geodesy/2010/River.xsd&quot;

When fixing a bug I fix it in the same namespace but if I&#39;m about to upgrade a schema then I need to create a new namespace but with upgrade month added:

    targetNamespace=&quot;http://schemas.company.com/Geodesy/2010/01/River.xsd&quot;

And if I have more than one upgrade in a month then just append a day too:

    targetNamespace=&quot;http://schemas.company.com/Geodesy/2010/01/17/River.xsd&quot;

Do you know any better approach?

How do I express the condition &quot;if value is not empty&quot; in the VBA language? Is it something like this?
                               
    &quot;if value is not empty then...&quot;

For instance, `%11.2lf` in C++ becomes `%11.2f` in Java.
How about for long format?

Take the following:

	public Class&lt;List&lt;String&gt;&gt; getObjectType() {
		// what can I return here?
	}

What class literal expression can I return from this method which will satisfy the generics and compile? `List.class` won&#39;t compile, and neither will `List.&lt;String&gt;class`.

If you&#39;re wondering &quot;why&quot;, I&#39;m writing an implementation of Spring&#39;s `FactoryBean&lt;List&lt;String&gt;&gt;`, which requires me to implement `Class&lt;List&lt;String&gt;&gt; getObjectType()`. However, this is *not* a Spring question.

**edit:** My plaintive cries have been heard by the powers that be at SpringSource, and so Spring 3.0.1 will have the return type of `getObjectType()` changed to `Class&lt;?&gt;`, which neatly avoids the problem.

Is there an easier way to setup the http client for preemptive basic authentication than what described [here][1]?  
In previous version (3.x) it used to be a simple method call (eg, `httpClient.getParams().setAuthenticationPreemptive(true)`).  
The main thing I want to avoid is adding the BasicHttpContext to each method I execute.

For c# developers that are staring out to learn Java, are there any big underlying differences between the two languages that should be pointed out?

Maybe some people may assume things to be the same, but there are some import aspects that shouldn&#39;t be overlooked? (or you can really screw up!)

Maybe in terms of OOP constructs, the way GC works, references, deployment related, etc.

Is there any reason why Java booleans take only `true` or `false` why not `1` or `0` also?

Why would anyone use `String.Format` in C# and VB .NET as opposed to the concatenation operators (`&amp;` in VB, and `+` in C#)?

What is the main difference? Why are everyone so interested in using `String.Format`? I am very curious.

Why use String.Format?

I&#39;m using String.format() in Java trying to emulate the printf() control channel available in C. I understand how to specify that a string should be placed in a field which takes 20 characters, 5, 2 ... with 3 decimals, 2, etc.  However, the strings are printed right-aligned in their field.

How do I left-align the strings?

Here&#39;s an example of a possible output which I would like to modify to left-align `EXECUTING` and `CREATED` in their fields.

    Process PID: 25    Status: -----------       EXECUTING
    Process PID: 36    Status: READY-SUSPENDED
    Process PID:  4    Status: ----------------        CREATED

*note: consider &#39;-&#39; as an empty space

How can I left-align strings using String.format()?

In the following code below, why do the two `string.Format` calls not behave the same way? In the first one, no exception is thrown, but in the second one an `ArgumentNullException` is thrown.


    static void Main(string[] args)
    {
        Exception e = null;
        string msgOne = string.Format(&quot;An exception occurred: {0}&quot;, e);
        string msgTwo = string.Format(&quot;Another exception occurred: {0}&quot;, null);
    }

Could someone please help me understand the difference between the two?
