A good variable name is one that is clear, related to the data it stores. Also, you should try to avoid confusions with other variables.
try making yourself..hope it will be useful ofr you!
The Finally block in java is used along with the try-catch statements. The usual structure is try { ..... } catch(Exception e){ .... } finally { ..... } In the finally block we usually have code that is used to perform clean up activities corresponding to the code in the try block. When an exception occurs in the try block control comes to the catch block and the rest of the code in the try block would not execute. In such cases we may need to have some code that cleans up the objects that we created/used in the try block. No matter what happens, the code inside the finally block would definitely execute. The best use of finally block is when we are connecting to the database. In the try block we would have the statements that instantiate the connection, prepared statement, result set etc. If the query fails then all these objects would be left open and the code would continue. So in the finally block we usually nullify these statements so that even in case of an error the unused objects are cleared. Example: Connection con; PreparedStatment PS; ResultSet rs; try{ con = ConnectionManager.getConnection(); PS = con.prepareStatement(query); rs = PS.executyQuery(); ...... } catch (Exception e){ e.printStackTrace(); } finally { con.close(); PS.close(); } In case of an error the connection & prepared statement objects would remain open if we do not have the finally block. Tip: Whatever code we have inside the finally block would be run definitely if the try block is invoked. We can even use the finally block to check if the try block was reached and executed. If the try executes then we can rest assured that the finally would also get executed.
If you have an exception you should fix mistake in your try block. If you want to run some code even after exception was thrown you can use full form of try block:try{...}catch (...){...}finally{...}Where the statement finally is what you need. Make sure that the code you run within this statement is not able to trow exceptions.
You can't, you have to come up with variables to calculate grades
You cannot 'install' programming languages. Instead, you can try to install a compiler or an IDE.
OOP means "object oriented programming" this means that you can make objects instead of C where you use procedural programming (it's advance try to google it :) )
LISP is designed for AI programming, give that a try.
Genaerally every try block maintain the one finally block or atleast one catch block or both. It mean try { try{ try{ } or } or } finally { catch(....) { catch(...){ } } } catch(.....) { : } finally{ : } Hear whenever we declar the try block without catch or finally bocks it show the compile time error like ' try without catch or finally' and also it is not possible to declare the any statements in between the try ,catch and finally blocks. ex: try{ } System.out.println("statement"); finally { } The above example show the compile time error 'try without catch or finally'. " Hear the finally block must be execute after excuting the try or catch block. Hence the finally block is used to release the resources like closing the streams and closing the jdbc connections." Hence in exception handling we use one finally block for one try block to release the resources.

Start learning 2d game programming. (SDL, Allegro, SFML or something simuler) Then you can try some 3d programming (DirectX or OpenGL are the most known libaries) OpenGL is cross platform and open source so it should be easier to find tutorials to.
No, if you try than Oh noes will pop up. This will happen because Google programming is not the same as Khan Academy plus, Google is copyrighted material.
You don't need computer programming for physics. Try it out; you might like it.

HYPOTHESIS: a hypothesis is what you think will happen. You should try starting it off with my hypothesis is... next it will.... then it will... finally it will...
well .. talking about in general terms (like making some newbie to understand, what the computer programming is about) so we must say that computer programming is like ..Programming a computer to do some task. in programming we create a sequence of instructions that enables the computer to do something.like we try to make the computer understand what we want to do so that it can help us to do that work. or even sometimes the computer can do that task itself and give the desired output.sourabh882008@yahoo.com
