Maybe showing your father points that shows how computer programming will be important for the future will help. If he doesn't understand your point, give him some time and he might come around.

Like anyone else in this thread I recommend studying what you want, and not what your father would want. It's your choice, you have to live with the decisions you make, and if he doesn't want to support you he is undermining your freedom. When you start studying you're an adult - you can make every decision in your own life without your father consent. I know it's hard to try and study without any support, but in the end I'd say it's worth it.
