How I can use this site result in my android app? I want send math expression to this site get answer in my app and display result to user?
You can actually code the relevant site as the required function. But if you want to use it, you can use it as a WebView and capture data about jsoup.

I recently started coding with Apex and have been utilizing the 'system.debug()' method. It helps me keep track of variables in my code by printing the variable in the 'debug log'. Now I am studying Java, and I was wondering if an equivalent method exists in Java. I would like to see what my variables are in certain parts of my code.
You can use a PrintStream, like System.out to call print or println in order to display your debug. You can also redirect System.out to file using setOut.
However, if you use an IDE and a debugger, you can create a breakpoint to the line that you wish to debug and let a debugger run until it reaches your line.

I create a Hashmap xxx
store all Thread inside Hasmap
when Thread finish , will remove it
is it a good practise?
Here is my code : https://gist.github.com/extralam/756484718c9e0cd57ddb
The right way, since Java5, is the use of the ThreadPoolExecutor.

Sorry in advance if this was already answered but what i need is for an user to input a date in this format AAAA/MM/DD. But when the user puts the year (4 numbers) the token(/) automatically appears not giving the user user the option to put it himself.
And the next question is how do i make the user only to input numbers without thinking in the before checks.
This in advance
Try MaskFormatter:
MaskFormatter formatter = new MaskFormatter("####/##/##");
JFormattedTextField textField = new JFormattedTextField(formatter);
'#' stands for only number input
I think you cannot do that at least in a multiplatform standard.
More info here but I don't think it will help. http://docs.oracle.com/javase/6/docs/api/java/io/Console.html
Maybe there are JNI multiplatform consoles somewhere that support it.

I was developing an java swing application to add view and modify the list of medicines.While adding the medicines it should show the list from the database(like google search box).For example if we press "p" it should show 'paracetamol' from the database.
You should implement a change listener on the text input box, when the text is changed, run a query to the database with the contents of the input box.
