windows - How to get output and give input from/to batch file using java -

-

How can I get output from a batch file, but input the batch file as well? My question is self-explanatory. As I created a small code to run a batch file: process process = runtime.gettime (). Exec ("(My file)"); . But what will happen now?

You can get input and output streams from the process by using the respective recipient methods. / P>

Edit:

getInputStream ()

and 

  getOutputStream ()
