There are many people learning JAVA now. After all, this JAVA is in a solid position. As for the training fee, it depends on where you learned it. Online and offline have their own advantages and disadvantages. Online should be cheaper, and there are thousands, but teaching interaction is inconvenient and some courses are not systematic. Offline courses should be differentiated, and the cost of basic courses is lower, ranging from thousands to 2W. However, the targeted JAVA courses with complete curriculum system are expensive, but the employment salary is also high after learning well. Above 8K in first-tier cities is not a problem, and some jobs can get above1w. The course fees in different regions are different, and the first-tier cities are higher than 2W. Courses in second-tier cities range from 1W to 2W, depending on the training institutions and courses. Cloud and Data JAVA courses are more conducive to employment by setting courses according to the real needs of enterprises. Students who want to learn JAVA can compare more and learn more.
