Can you guys give me some ideas for algorithm for 4x4 sudoku solver in java laugauge. I am currently having diffcultly in figuring out a agorithm. I have read wikipedia page for 9by9 solver, but maybe you guys can simplify the idea of it
Here's a page that explains this with a 4x4 grid. By the way, you really should try Googling before asking a question here. I just searched "sudoku solver example program" to find this.

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.

I need to know why Jump Point Search is better than A* for path finding?
As to why Jump Point Search is better than A*, it is because, Jump Point Search algorithm does not evaluate all nodes like A* but rather "jumps" or skips over few nodes in the tree/graph. This ensures that fewer nodes are expanded and hence quickening up your algorithm's running time.
A detailed paper on this can be found here:

how can I devide my main class and what criteria to choose fo dividing ?
Good evening,
if I understand your question well, I may advice you to read the "Clean Code " of Robert C.Martin. It is a great agile book, that can help your to divide your code.
Good luck

Hi am new to java is there any other way to find string length pixel without using awt and swing
No. The length depends on how the String is rendered, so obviously only libraries that know how to render a String will be able to tell how big it would be.
It's as if I asked you to tell me the required dimensions if I wrote my username on paper.

I am a very new programmer, it is part of my degree requirements and I am having a hard time with it. I am working on basically a three part GUI and I am wondering how I would create a JTextArea that will display each item that is entered.
Start by taking a look at Creating a GUI With JFC/Swing, this will give you a basic grounding in how to use Swing.
Take a closer look at How to Use Text Areas for specific details about how to use JTextArea
