After attending Java training, you will gain some skills and knowledge, but when looking for a job, lack of practical work experience may be a challenge. However, there are still some ways to increase your competitiveness and your chances of finding a job:

Practical projects: In addition to training, it is very important to complete some practical projects by yourself. This shows that you not only know Java in theory, but also can apply your knowledge to practical problems.

Internship: Although it is an unpaid internship or a short-term internship, it is a way to gain practical work experience. Internship experience will have a great influence on your resume.

Network: use personal relationships and networks to find opportunities. Sometimes, you may find some entry-level opportunities through the introduction of friends, family members or teachers.

Job Search Website: Use the recruitment website and the company's career website to find a position that suits your skill level. Sometimes companies will recruit junior developers and provide training.

Resume optimization: highlight the skills you have learned in training and emphasize the achievements you have made in the project in your resume.

Interview preparation: prepare some common technical interview questions and be familiar with the interview process. Show your learning ability, problem-solving ability and communication ability.

Remember, although your lack of work experience may make your resume look relatively short, you can still attract the attention of some companies by showing your learning ability, practical project experience and enthusiasm for the industry.
