Execute commands in cmd using Java

I am using the following code to run the cmd.exe and the cmd window appears which is fine.

Runtime runtime = Runtime.getRuntime();
    try {
        Process p = runtime.exec("cmd.exe /c start");
    } catch (IOException ex) {
        Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
    }

My question is that how can I run the following command on the cmd before it appears using java 

ghci test.hs

my target is to make the command line looks like the following image once it appears

run 

Runtime runtime = Runtime.getRuntime();      
try { 
    Process p = runtime.exec("start cmd.exe /k \"ghci.exe test.hs\""); 

} catch (IOException ex) {
 Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex); 
}
