问题 My Java program builds some files (.html and .txt-files) in one directory. To finish a project I'd like to "pack" these files for example to send it to another person. But the other person should not be able to simple "unpack" the file and manipulate the html/txt-Files. Only open the packed file with my Java program. My idea was, to zip the directory with a master password (set in the Java program) protection. After that I can send the zip-file via eMail and the other person will only be able

问题 How do I open another app in a split screen in the android N (SDK 24)? In the documentation I found this: Launch New Activities in Multi-Window Mode When you launch a new activity, you can hint to the system that the new activity should be displayed adjacent to the current one, if possible. To do this, use the flag Intent.FLAG_ACTIVITY_LAUNCH_TO_ADJACENT. Passing this flag requests the following behaviour: If the device is in split-screen mode, the system attempts to create the new activity

问题 I need to write a web application which receives a lot of HTTP requests and takes a long time (30s to 2min) to process each request (in turn making other network requests) before returning a response. Because there would be a lot of requests coming in and those connections are held open I'm thinking of going down an event driven route, which leads me to think Netty is appropriate. If each request takes a long time to process, is that going to block netty's processing? Or can I receive a

问题 I am drawing some objects on a JFrame such as circles, rectangles and arcs between them. I was wondering how I can implement an Undo button bearing in mind that the ones I found are targeted at text fields and writing in them. I don't have code to show and I wish to receive advice on how to implement it. Is it possible to 'register' the last event that occurred and then delete it? I have a very simple code about deleting the circles for instance. It works only for them and I know that it is
