I'd like to get all nodes in a JSoup doc. What's the best way to do this (in Java or Scala?)
Thanks
You can use * selector:
Elements elements = document.select("*");
document.getAllElements() works, and produces the same results as document.select("*")

I am writing a program with IPOPT in Java and due to the nature of the problem, it is rather difficult to provide a Jacobian matrix.
The question is basically the title:
Is it possible to use IPOPT without Jacobian matrix and if so how?
i couldn't find anything in the documentation, but maybe i am just blind.

So the question is basically if to have
getDriver().findElement(by).clear();
or to have
String text = getDriver().findElement(by).getText();
if (!text.equals(""))
getDriver().findElement(by).clear();
and after that a sendKeys.
Note: Most of the times, the field is empty.
This is simple math
getDriver().findElement(by).clear();
Costs as
getDriver().findElement(by).getText();
To the second line you add an if check and maybe getDriver().findElement(by).clear(); anyway.
So just call clear() without a check.

I have this code in Python:
if word[x:x+2] in twowords:
(twowords is a list). I can't figure out how to write in twowords in Java.
It looks like Python uses [x:y] to create a substring. You can use the substring method for that purpose, with the same parameters.
There is no in syntax in Java, but all Lists in Java support the contains method.
Try
if (twowords.contains(word.substring(x, x+2)))

I'm thinking on possibility of making a Huffman code without "node".
It's based on the nodes then my question seems a bit ambiguous.
I know,maybe we have to use string's abilites ...
Is it possible ? and if "YES" how Is it possible in java?
Thanks.
You can use indices instead of nodes but you need somewhere nodes and/or vertices.

getJSON("sample.json") is not working when invoking from html in D:" { "name" : "blah" } getJSON("D:/data/sample_json.json",fun
You won't be able to request JSON by using a path to a file on your system. Its hard to say if this is the only thing you'll need to change though.
