Код:

public boolean runProgramAndWait(String runCommand){
            Process process;
            java.lang.Runtime runtime;
            try{
                runtime = Runtime.getRuntime();
                process = runtime.exec(runCommand);
                process.waitFor();
                return true;
            }catch (InterruptedException e){
                return false;
            }
            catch (Exception e){
                 return false;
            }
        }

Вот так должно работать.
