As others said, you may run your external program without xterm. However, if you want to run it in a terminal window, e.g. to let the user interact with it, xterm allows you to specify the program to run as parameter.

xterm -e any command

In Java code this becomes:

String[] command = { "xterm", "-e", "my", "command", "with", "parameters" };
Runtime.getRuntime().exec(command);

Or, using ProcessBuilder:

String[] command = { "xterm", "-e", "my", "command", "with", "parameters" };
Process proc = new ProcessBuilder(command).start();
