Question

Is there any way to make a Java program (in Windows) that just acts as a wrapper around a PE
(.exe), passing all stdin input to the program and writing out to stdout everything that the PE writes out.

I need this because the interface for a program only allows Java classes, but I want it to run some code that I’ve put together in C++.

Thanks in advance.

edit: portability is 0% important. This only needs to work in Windows and will never be needed to work anywhere else.

Take a look at ProcessBuilder:

 ProcessBuilder pb = new ProcessBuilder("myCommand", "myArg1", "myArg2");
 Map<String, String> env = pb.environment();
 env.put("VAR1", "myValue");
 env.remove("OTHERVAR");
 env.put("VAR2", env.get("VAR1") + "suffix");
 pb.directory("myDir");
 Process p = pb.start();

and another example of it.
