How to clear the console?

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.

I have a java program and I want it to be able to print out its location on the computer. For example, if I were to place the program in the Downloads folder, and run it, it would print out the path to the file.
new File(MyClass.class.getProtectionDomain().getCodeSource().getLocation()
.toURI()).getPath();
make sure to change the Myclass.class stuff
then system.out.println(File)

You should check whether your getClass().getResource() call actually returns a non-null value. I assume your css-file is not in the right place.

How Do I Eject a Volume in 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.
