Java: Can't execute external exe with arguments

Question

I’m trying to run an external program with arguments. The program can take different types of arguments, for instance avl tip.avl or avl < test.ops<

Answer 1

Thank you both, the below works as expected.

File pipe = new File("test_0.ops");
ProcessBuilder pb = new ProcessBuilder("avl");
pb.redirectInput(pipe);
final Process p = pb.start();
