The cost of java training for Changsha Power Node is about 20,000. However, the specific fees may vary due to factors such as the curriculum and the qualifications of lecturers. I suggest that when you choose a training institution, you should first know their curriculum, lecturer qualifications and other information, and then make a choice according to your own needs and budget. At the same time, we also remind everyone to pay attention to the false propaganda and bad behavior of some bad institutions to avoid being deceived.
