Is Java pass-by-reference?

I always thought Java was pass-by-reference, however I've seen a couple of blog posts (e.g. this blog ) that claim it's not. I don't think I understand the distinction they're making.

PHP pass function as param then call the function?

I need to pass a function as a parameter to another function and then call the passed function from withing the function...This is probably easier for me to explain in code..I basically want to do something like this:

Passing parameters to a JQuery function

I'm creating HTML with a loop that has a column for Action. That column is a Hyperlink that when the user clicks calls a JavaScript function and passes the parameters...

example:

<a href="#" OnClick="DoAction(1,'Jose');" > Click </a>

<a href="#" OnClick="DoAction(2,'Juan');" > Click </a>

<a href="#" OnClick="DoAction(3,'Pedro');" > Click </a>

...

<a href="#" OnClick="DoAction(n,'xxx');" > Click </a>

I want that function to call an Ajax jQuery function with the correct parameters.

Any help?
