The pre-job training institution for java engineers is the java training class. Pre-job training should be regarded as the class type of java employment class. Employment courses are generally more courses of project practice. After graduation, I joined the java employment class, which is still very good on the whole, because more than half of the courses are project practice, which enriches my experience in project development. When I look for a job, the salary of someone with project experience will definitely be higher than that of someone without project experience, so I think in the short term.
