All of the above
Try block is followed by finally block as an alternative . But usually it is followed by a catch block. Both are equivalent.
A Catch block is part of the exception handling mechanism in Java. It is used along with the try block. Ex: try { ... } catch (Exception e) { ... } The catch block is used to catch & handle the exception that gets thrown in the try block.
A try block must have a corresponding catch or atleast a finally block. The purpose of a try block is to identify areas in the code where exceptions may be generated and handle them. So, if you dont have a catch block, the whole purpose of using the try block is defeated
No, unless your school didn't block the website. Schools mostly block uneducated websites. If you are lucky, try to not get caught by a teacher, but if you take my advice don't do it. Or you'll get in trouble. People of integrity tell the truth ALL the time.
Yes, a try-catch block can be nested. It is placed around the code that might generate an exception.
If the schools IT guy is worth anything you can't. But keep playing with things to try and figure it out, we love it when kids screw up the computers (note the sarcasm)
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.

try... catch is used for error handling. The "try" block simply contains an instruction, or a group of instructions, that might fail at runtime.
Because the exception, like any other declared object that needs visibility outside the block, must have scope outside the try block.
