Problem in code

[madhoriya22]

Hi,
Here is the code snippet in which I have problem. When this part throws exception, request is sent to ErrorPage.jsp. Now the problem is, after forwarding the request to errorPage, the program should halt at this place and this value should not go in database...It takes hoursSpent value as 0......how should I halt flow at this point

double hoursSpent = 0;
        try {
            hoursSpent = Double.parseDouble(request.getParameter("hoursSpentInput"));
        }catch(NumberFormatException nfe) {
            System.out.println("not a number"+nfe);
            request.setAttribute("Message","Enter a number in 'Hours Spent'");
            request.getRequestDispatcher("ErrorPage.jsp").forward(request,response);
        }
.......//some code here

After the catch clause has executed control flow continues at your
'// some code here' where you most likely fiddle with your database again.
Don't do that, simply return at the end of your catch clause.

Those colour are pre-set; given the kind of code tag, the colours differ; I don't
know the reason behind this all; here are a few examples

for (int i= 0; i < n; i++) System.out.println("Hello world");
 

for (int i= 0; i < n; i++) printf("Hello world\n");
 

for (int i= 0; i < n; i++) cout << "Hello world" << eol;
 

I really have no idea why those colours should be different; and please don't ask
me about those line numbers either; I'm innocent ;-)
