How to clear the console?
(14 answers)
Closed 2 years ago.
I want to know that how can I clear console screen in java.
The IDE I am using is IntelliJ IDEA.
For example: In C language we use to write: clrscr();
That is not possible in IntelliJ as the console is not a real terminal.
There are however different console plugins where this is possible. One of which is the Grep Console.

Probably not. For Windows, you need to deal with the registry. Writing to the Windows registry in Java is discussed in read/write to Windows Registry using Java.

Is there any simple way to eject the D drive in Windows 7 using Java? I don't particularly care about cross-platform compatibility at the moment. I've done some research andRuntime.getRuntime().exec(); has shown up most... but I have no idea what to put as the string parameter, I've tried a few things but it just throws up on me!
You can pass the vbscript code to eject the cd as an argument in the exec() function.

Can we read the OS environment variables in Java?
(2 answers)
Closed 9 years ago.
This may be a very simple problem, but I couldn't find an answer googleing and I'm in a rush - so I'd appreciate fast code examples.
I have an environment variable on the OS I would like to read using Java code. I've tried System.getProperty, but that only seems to work for the -D variables supplied directly for the JVM.
How can my Java code read OS variables?
Try System.getenv(String name)
