Java可见命令行

Question

I just tried to execute a java command using runtime like this:

Runtime.getRuntime().exec("shutdown -s");

to shutdown the computer, but I am training on a project that will get both my electronics and computer skills so I want to execute an avrdude command to program the mcu from Java and make a GUI program. So I want the cmd window to be visible when I run the command. I just made it visible by:

Runtime.getRuntime().exec("cmd.exe /c start");

but I cant write on the window I just created, any help pls????

thanks all

Answer 1

Following would do it for you.

CMD.EXE /K your_command

Answer 2

I got an idea but still need some help! What about making a .bat file and running it using java File class but still when I make a bat file and try to run I get the command multiple times like this:

but all I did was only write avrdude in the bat file:

I just looked it up in the internet and figured out a solution which is making a .cmd file instead of a .bat file and that worked great without looping thanks for all the repliers..!! :)
