f(x) is a Method wich throws the Exception of F_Exception type.

try {
f(x);
} catch (F_Exception e)
{
e. ...
}

It's just that:
If f(x) produces the exception, the program will stop the execution of the code inside the try-catch block and go to the catch-block.
There also exists a "finally" option, but you won't need it most of the time.
You should read about that in a Java book.
