what should we do in the catch block?

/*what should we do in the catch block?
 * first, we need to print the stack trace by using e.printStackTrace();
 * second, we need to print out the runtime variables to help us determine what caused this exception
 * third, this is not must, but you need to ask yourself a question, do you need to terminate the program when the exception happens?
