Use [`copyOfRange`][1], available since Java 1.6:

    Arrays.copyOfRange(array, 1, array.length);

Alternatives include:

- [`ArrayUtils.subarray(array, 1, array.length)`](https://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/lang3/ArrayUtils.html#subarray-T:A-int-int-) from Apache [commons-lang][2]
- [`System.arraycopy(...)`][3] - rather unfriendly with the long param list.

  [3]: https://docs.oracle.com/javase/10/docs/api/java/lang/System.html#arraycopy(java.lang.Object,int,java.lang.Object,int,int)

    String[] subset = Arrays.copyOfRange(originalArray, 1, originalArray.length);

Stream API could be used too:

    String[] array = {&quot;A&quot;, &quot;B&quot;};
        
    Arrays.stream(array).skip(1).toArray(String[]::new);

However, the answer from Bozho should be preferred.

It seems like I have not clearly communicated my problem. I need to send a file (using AJAX) and I need to get the upload progress of the file using the [Nginx HttpUploadProgressModule][1]. I need a good solution to this problem. I have tried with the jquery.uploadprogress plugin, but I am finding myself having to rewrite much of it to get it to work in all browsers and to send the file using AJAX. 

All I need is the code to do this and it needs to work in all major browsers (Chrome, Safari, FireFox, and IE). It would be even better If I could get a solution that will handle multiple file uploads.

&lt;strike&gt;I am using the [jquery.uploadprogress plugin][2] to get the upload progress of a file from the NginxHttpUploadProgressModule. This is inside an iframe for a facebook application. It works in firefox, but it fails in chrome/safari.

When I open the console I get this.

    Uncaught ReferenceError: progressFrame is not defined
    jquery.uploadprogress.js:80

Any idea how I would fix that?

I would like to also send the file using AJAX when it is completed. How would I implement that?

I have a model, and I have a view that displays a form for creating a new object based on that model.  Let&#39;s call that form, `Form1`.

Once the user submits `Form1`, the object is created. I then want to display, on the following page, a second form `Form2`, which asks the user to check off various options before the object is saved to the database.

My problem is probably extremely basic. I don&#39;t know how to create `Form2`, given that it is not tied directly to the model. Because I am a `Rails` newbie, I have only created forms as following:

    form_for(@object) { |f| ... }

*`@object` is an object instantiated from the model*

**Problem**: I do not believe that kind of code will work for my purposes here. How do I create `Form2`, given that it must not be based on `@object` or `@object`&#39;s model?

**Some specifics from my app**:  

The site accepts values (`Form1`) before redirecting to an `OAuth` server. 

When the user verifies her credentials on the `OAuth` server, she is redirected back to my site. An `XML-RPC` request then retrieves information about the user&#39;s account on the `OAuth` server.  

The `XML` response may indicate that the user has only one account on the `OAuth` server. If so, some values are retrieved from the `XML` and added to the object--which is then (finally) saved in the database--and the user is redirected to a success page.  

However, if the `XML` response indicates that the user has multiple accounts on the `OAuth` server, I want to display a form (`Form2`) that allows the user to select which accounts on the OAuth server to associate with my site.  So `Form2` really asks the user *how many* objects to create, rather than about specific attributes of an object.

I have a `String[]` that has at least 2 elements.

I want to create a new `String[]` that has elements 1 through the rest of them. So.. basically, just skipping the first one.

Can this be done in one line? easily?

I wonder what the functionality of adding &lt;code&gt;@Override&lt;/code&gt; in front of the code we would like to override is. I have done with and without it, and it seemed that everything was just going well (at least, for me).

Do we really need @Override and so on when code Java?

I&#39;m following this [tutorial][1].

It works great but I would like it to return an array with all the strings instead of a single string with the last element.

Any ideas how to do this?

I have the following parametrised JPA, or Hibernate, query:

    SELECT entity FROM Entity entity WHERE name IN (?)

I want to pass the parameter as an ArrayList&amp;lt;String&gt;, is this possible? Hibernate current tells me, that

    java.lang.ClassCastException: java.util.ArrayList cannot be cast to java.lang.String

Is this possible at all?

**ANSWER**: Collections as parameters only work with named parameters like &quot;`:name`&quot;, not with JDBC style parameters like &quot;`?`&quot;.

In a post entitled [&quot;AOP Fundamentals&quot;](https://stackoverflow.com/questions/4819814/aop-fundamentals), I asked for a *King&#39;s English* explanation of what AOP is, and what it does.  I received some very helpful answers and links to articles that helped fill me in on all the theory.

But now AOP&#39;s got my full attention, and all these articles and chapter excerpts are fantastic, but in **every single case** they consist of lofty theory, vague UML models, and order of abstraction that are way too high-up for my liking.

Here is my understanding of AOP theory, just to clarify, so if you see something that looks wrong, let me know!:

1. Cross-cutting concerns such as Logging, Authenticating, Synchronizing, Validating, Exception Handling, etc. become highly-coupled in non-AOP systems as they are used universally by almost every component/module in the codebase.

2.  AOP defines **aspects** (classes/methods) that abstract these cross-cutting concerns with the use of **join points**, **advice**, and **pointcuts**.

  a. *Advice* - The actual code (method of an aspect, perhaps?) implementing the cross-cutting concern (i.e. doing the actual logging, validating, authenticating, etc.)

  b.  *Join Point* - An event that is triggered in non-AOP code that causes a particular aspect&#39;s advice to be executed (&quot;woven&quot; into the non-AOP code)

  c. *Pointcut* - Essentially, a mapping of join points (triggering events) to advice execution

3.  All aspects are modularized (LoggingAspect, AuthenticationAspect, ValidationAspect, etc.) into components and registered with an **AspectWeaver**.  When non-AOP/POJO code comes across a join point, AspectWeaver &quot;weaves&quot; (integrates) the mapped advice around the non-AOP code:

&lt;pre&gt;
public class LoggingAspect
{
    // ...

    public void log(String msg) { ... }
}

public class ExceptionHandlingAspect
{
    // ..

    public void handle(Exception exc) { ... }
}

public class NonAOPCode
{
    // ...

    @LoggingAspect @ExceptionHandlingAspect
    public void foo()
    {
        // do some stuff...
    }
}

// Now in the driver
public static int main void(String[] args)
{
    NonAOPCode nonAOP = new NonAOPCode();
    nonAOP.foo();
}

// The AspectWeaver *magically* might weave in method calls so main now becomes:
{
    NonAOPCode nonAOP = new NonAOPCode();

    log(someMsg);
    nonAOP.foo();
    handle(someExc);
}

&lt;/pre&gt;

**The $64,000 Question:** Is my understanding of Java-based AOP on target, or way off, and why? How could one **correctly** use annotations to implement aspects, advice, join points, pointcuts and this so-called aspect weaver?
