If you are looking for JAVA, computer science and engineering (such as mathematics, automatic control, etc.). ) are all conditions for extra points, if you can meet the above conditions. Then write it down.

If not, you'd better not write it and explain it when he comes to ask you. If you are not a computer major, but you have a deep understanding of JAVA and there are many examples, it doesn't matter which department you are in.

In addition to the department, the most important thing is whether you have actual combat experience in JAVA. If so, a long introduction will be very useful.
