Runtime and Commands for Mac

[switch]

I would like to know if anyone knows how to execute, command + option + Q using Runtime.getRuntime().exec("//code here"); this is for mac os x lion. I have a problem with the preview app. There is no com.apple.Preview.savedState folder... believe me, I've looked everywhere it could or should be and its not there and have changed the system preferences to stop it but Preview still shows previous images after reopening. I could just use the command + option + Q keys to close the last opened image in preview, but this is a program and it should be automatic. I've solved the problem by writing a different program using JInternalFrames, but I like using the simpler and smaller program. Right now I'm using Runtime.getRuntime().exec("killall Preview"); but that command only closes the Preview.app. When the program needs to open another image, it opens the new image plus the previous image and or images. killall Preview is a mac terminal command, but I don't know how to execute command + option + Q in the terminal. If I did I could get this to work. any suggestions?

switch(i) {
case 0: execute this;
break;
}

What's the preview (or maybe Preview) app?

Preview is a built in application that come pre installed with mac os x. It is an imaging application kind of like mspaint, except a little more advanced. To open with java you can use
Runtime.getRuntime().exec("open -a Preview.app"); -a is mac terminal command for the applications folder. As for windows you could use Runtime.getRuntime().exec("cmd /c start mspaint.exe " + imagepath); imagepath being a user defined string that includes the path, filename and filename extension to the file.
