First of all, watching videos is a very convenient way to learn. Now there are many online platforms and social media that provide a large number of Java learning videos. You can learn the knowledge and skills of Java by watching these videos. The advantage of this way is that the time and place of study are flexible, and you can study anytime and anywhere. In addition, video learning is usually vivid, which helps you to better understand the knowledge points of Java.

However, video learning is just a way of learning. It can help you understand some basic knowledge and methods, but practical operation and interactive learning are still very important. So signing up for a training class may be more suitable for some people. Training courses can provide systematic learning content and guidance, so that you can master Java knowledge and skills more comprehensively. Training courses usually have face-to-face lectures and interactions, which can help you better understand the principles and applications of Java. In addition, the training course can also provide practical projects and exercises, so that you have the opportunity to practice and improve your practical ability.

Combined with my personal experience, I tend to learn Java through video. I think video learning is a very flexible way of learning. You can arrange your own learning plan according to your own learning progress and understanding. By watching the video, you can systematically learn the basic knowledge and core skills of Java and understand some practical application cases. At the same time, video learning can also provide opportunities for repeated learning. For some difficult knowledge points, you can watch videos repeatedly to deepen your understanding.

Of course, everyone's learning style and needs are different, so it is very important to choose the learning style that suits you. If you are very interested in Java and have a certain ability of self-study, then learning through video may be a good choice. But if you want to learn Java more systematically and get professional guidance and support, then signing up for a training class may be more suitable for you. No matter which way you choose, the key is to keep learning enthusiasm and motivation, and persist in learning and practice.
