Still need some other knowledge to assist. If your java is strong, you must emphasize your basic java skills during the interview, which is the basis of doing the project. Many companies will attach great importance to you, and other knowledge can be put into company training. So it's possible.

I only knew java at first, but it was relatively easy to find a job after attending a software training class.

Let me recommend it. I am in Shanghai Pu Jie Software Company. If you want to train, you can contact yourself. You can also look for a job directly. If the company recruits, you must be able to work as soon as you take up your post. If it is excellent, there will be special cases! Good luck!
