 | Make `scan` a private static variable and initialize it in the main() method. In that case, you'd be able to use `scan` in all your static methods. In case you decide to clean up stuff, just remove the static modifier from the scan declaration and all the methods and it …  |
 | To add to the above posts, make sure you quote your keywords if you are looking for an exact match. For e.g. if you are looking for sessions word in PHP code snippets, your query should be: site:daniweb.com/web-development/php/code "sessions". Without quoting session, you'll get code snippets containing both the words, …  |
| | What exactly is the problem here? You want to test out your binary tree? Also, is it required that you create one and not use the set data structure present in the Java standard library? |
 | > can any one tell me how to find unique values in array list? Assuming your items of the `List' implement an appropriate equals/hashCode() method or the Comparable interface, converting it to a `Set' would be the simplest way to get the unique elements. |

| | Another solution would be to use the DecimalFormat class. [code] public static void main(String[] args) throws Exception { double[] doubles = {5.300000000000001, 123231.600000000000001, 88.695555555 }; final DecimalFormat fmt = new DecimalFormat(".00"); for (double d : doubles) { System.out.println(fmt.format(d)); } }[/code] |

| | Notepad is not a compiler, it's a text editor used for typing in Java code. If you are just starting out, I'd recommend grabbing any text editor which highlights the code for you along with smart indentation. There are a lot of options in there: Notepad++, Gedit, Scite etc. I've … |
 | > Adding to that, it might also be worthwhile using System.getProperty("file.separator") to ensure compatibility on as many systems as possible. Or better yet IMO, try not to mess with FS paths thinking of them as strings and use appropriate constructors:[code] final File homeDir = new File(System.getProperty("user.home")); final File defaultFileStore = … |

| | Unfortunately no easy way of doing this. There are two contenders in Java land (assuming you are talking about actually interacting with pages rather than just scraping the web page ignoring the JS part): HtmlUnit and Selenium. HtmlUnit works pretty good for simple and compliant web pages. I have successfully … |

| | AFAIK, you require "superuser" (also called as "root") privileges for binding to ports below 1024 and `sudo` does exactly that, run the program as a "superuser". From the sudo wikipedia entry: [quote]By default, sudo will prompt for a user password but it may be configured to require the root password, … |
| | Re: What's next? A few months back Google had acquired an organization which specialized in created UI builders for Swing / SWT (the toolkit which powers Eclipse) and open sourced it. Not sure how good it is [URL="http://code.google.com/javadevtools/wbpro/index.html"]but worth a try[/URL] if you are into creating drag-n-drop UI's. |
| | Depends on how good your preparations are. Kathy Sierra books are pretty good when it comes to certification preparation, for e.g. [URL="http://www.amazon.com/SCJP-Certified-Programmer-Java-310-065/dp/0071591060"]this one for SCJP 6[/URL](called something else now but doesn't matter AFAIK).

| | If you want to modify a `List` while iterating on it, the simplest solution would be to use a list iterator as opposed to a regular iterator. List iterators allow destructive updates on the list while iterating over it. [code]public static void main(String[] args) throws Exception { List<String> lst = … |
 | There is no "pure Java" way of doing that. There are a couple of "curses" bindings floating around for Java but that's it. The mess of outputting a bunch of line feeds is nothing compared to considering using a full fledged JNI-dependent third party library just for a better console … |
