College students want to change careers and learn to do Java, so it is suggested to combine self-study with training. College students have more spare time, so they can buy some related books to learn the basics first. When they need to practice to a certain extent, they can go to the corresponding training class to practice and consolidate their basic knowledge.

Finally, in the process of learning java, we should persevere, take corresponding notes while reading, and find relevant information on the Internet in time for those who don't understand, so as to learn from relevant videos in the early stage and master the basic knowledge systematically. However, java will eventually be applied to practice, so training courses are essential, and the practical skills learned in training courses will be of great help to such work in the future.
