With the popularization of higher education and the continuous expansion of university enrollment, today's job market is facing increasingly fierce competition. Students majoring in computer science, in particular, can hardly get a successful job if they lack practical work experience and professional skills. Therefore, IT is a good way to participate in vocational IT training and improve your professional skills.

In all IT industries and related fields, Java applications occupy a very large proportion, and the back-end of large-scale websites, large-scale enterprise-level applications and informatization of large-scale enterprise management systems in communication, network, finance and other industries are closely related to Java.

Now many emerging languages and fields need Java to lay the foundation. Therefore, Java development engineers are particularly important. There is a growing demand for such talents in major industries and enterprises, and the salary is also considerable.

For those college students who are confused and don't know what career to choose after graduation, especially those majoring in computer science, IT will improve their employment opportunities and success rate to participate in vocational IT training developed by Java and re-employment after upgrading their professional skills.

At present, the difficulty of college students' employment is the result of many factors. Future college students need to pay attention to improving their literacy and practical experience, reasonably adjust their employment expectations and choose their employment direction.
