printing

问题 I'm writing a command line program that makes use of println to display text in a very specific format. The problem I encounter is that every time I ask the user to enter something via Scanner.nextLine(), the console automatically echos their input in the console. Is there a way to disable the console from immediately displaying the user's entered text? In case it matters, I am running Linux. 回答1: You can use the Console class and readPassword() method that comes with Java since version 6.

问题 I need some advice with the Java Print API. I have a program that goes through a Vector and prints each item on its own line. I'm trying to make it so when the line count reaches a certain number, it starts a new page. I've been looking at a Java Tutorial example to figure it out, but it's still not working. In debug mode, everything appears to be working properly, but for some reason it's printing the second page on the first sheet of paper and leaving the second sheet blank. Does anyone

问题 Is there any easy way to print Flash Charts (Open Flash Charts 2) within a web page. Flash doesn't seem to print at all. I'm maintaining a health site for a client, and we use Open Flash Charts to draw multiple line charts for patients dynamic data.

Unfortunately I can't provide a link to the page as an example at the moment as the patient

问题 I have a WebBrowser control in a Windows Forms Host in a WPF application. I know that in order to print it's contents, I use simply WebBrowser.Print() , however, how can I tell the printer to print the contents in landscape rather than a portrait orientation? I've been searching the Internet on this and oddly enough, it seems to be actually something that is a bit hard to do -- is this really the case?

问题 Using latest fullcalendar.io, the number of weeks that are displayed in month view is appropriate for the first month that renders. When using the prev/next buttons, if the next/prev month has less weeks than the current month, it still renders the current month's number of weeks. Right now it's May 2015.
