Deciding whether you need to attend Java training depends on your background, learning objectives and time schedule. If you have a certain understanding of Java programming language and want to further improve your skills, it is necessary to participate in Java training. Training can help you understand all aspects of Java, including grammar, object-oriented programming, exception handling, assembly framework, generics, multithreading and so on. Through training, you can also learn common technologies and tools in actual project development, such as Spring framework, Hibernate, Java EE, etc. These technologies and tools are very popular in today's software development.

As for this training institution, I can't give a specific evaluation. However, when selecting training institutions, we can consider the following aspects:

Faculty: Understanding the teacher background and teaching experience of training institutions can be obtained through official website, course introduction or some online evaluation.

Teaching quality: Teaching quality is an important consideration. You can learn about the curriculum, teaching methods and student feedback of this institution.

Curriculum: Learn about the courses offered by training institutions and see if these courses meet your learning needs and interests.

Practice project: Practice project is a very important part of learning programming. Understand whether the training institutions provide actual combat projects, the complexity and quality of the projects.

Price: Consider whether the tuition fees of training institutions are reasonable and whether there are other fees (such as textbook fees and examination fees).

In a word, there are many factors to consider when choosing a suitable training institution. If you are interested in this institution in Chongqing, I suggest you know about its curriculum, teaching staff and teaching methods before making a decision.

Let me remind you that attending Java training is just a way of learning. It can help you learn and master some knowledge and skills systematically, but it does not guarantee that you will become an excellent Java development engineer. Therefore, while attending the training, you need to make efforts and time, and constantly improve your skills and abilities through practice and self-study.

What I want to say is not to be influenced by some negative comments. When choosing a training institution, you can refer to some information from different channels, including official website, course introduction, student feedback, social media and so on. At the same time, we should keep an open mind, don't easily believe some irresponsible recommendations or advertisements, and make wise choices according to our actual situation and needs.

In a word, if you are interested in Java programming language and want to further improve your skills and abilities, it is necessary to participate in Java training. However, choosing a suitable training institution requires careful consideration of many factors.
