Answer 1

If you want to make the window remain for a while, there are 3 ways:

• Run that command javac MyProgram.java java MyProgram in a Command Prompt window (fire up a new one, navigate to your working directory, execute it)
• Get a char ( Scanner a; ... ; a.nextLine() ) at the end of your program, you can then enter something or simply press a to make the program complete.
• Make the current thread sleep for some time so that you can see the output. Try: try { Thread.Sleep(1000); } catch (Exception e) {} try { Thread.Sleep(1000); } catch (Exception e) {}

It happens because at the end of the day it is a program. And it terminates once it is done with its execution..in your case, printing stuff.

You can manually open a command prompt and then drag and drop the .bat file onto this command prompt and run it. This way, you would still have the window open.
