Java Programming call an exe from Java and passing parameters

Question

I m figuring out a mechanism to call an exe from Java and passing in specific parameters  How can I do   Process process   new ProcessBuilder  C   PathToExe  MyExe exe   start    InputStream is   process getInputStream    InputStreamReader isr   new InputStreamReader is   BufferedReader br   new BufferedReader isr   String line   System out printf  Output of running  s is    Arrays toString args     while   line   br readLine       null      System out println line       The previous code works  But I m not able to pass parameters in  MyExe exe accepts parameters  An other problem is when PathToExe has blank spaces  ProcessBuilder seems not working  For example   C   User  My applications  MyExe exe   Thank you

You re on the right track  The two constructors accept arguments  or you can specify them post-construction with ProcessBuilder command java util List  and ProcessBuilder command String

Below works for me if your exe depend on some dll or certain dependency then you need to set directory path   As mention below exePath mean folder where exe placed along with it s references files   Exe application creating any temporaray file so it will create in folder mention in processBuilder directory            ProcessBuilder processBuilder   new ProcessBuilder arguments   processBuilder redirectOutput Redirect PIPE   processBuilder directory new File exePath    process   processBuilder start    int waitFlag   process waitFor      Wait to finish application execution  if  waitFlag    0         int returnVal   process exitValue
