Detect operating system in java In the following article, there is a short Java snippet that can be used to read the operating system of the computer running the Java program.
In addition, it is the first Java snippet at all here in the blog. Although I have been writing a few lines of Java code again and again for a couple of years, I really couldn’t befriend myself (especially with regard to my C # passion) with Java so far yet. But since I have to deal more and more with Java on the job, however, this will soon be reflected in the blog. But let’s come to the Snippet now…

Press Win-Taste + R key

Recently, I bought a netbook for my workshop to control a laser engraver (the DK-8 from Neje). Unfortunately, I had overlooked a small detail. The display of the netbook has only a native resolution of 1,024 x 600 pixels. However, the window of the control software requires at least 800 pixels in height, so that some of the software is not visible and thus can not be operated.
But remedy could be created by a small adjustment to the operating system. (In my case Windows 7 Starter.) By changing a key in the registry, the resolution can be increased beyond the native resolution. That’s how it works…
Increase maximum resolution in Windows
In order to support higher resolutions than the display’s native resolution, a registry key must be adjusted. Therefore open the Registry. (Either via the search in the start menu with the term “regedit” […]
