After learning Java, I submitted my resume for almost half a year, and no one responded, not even an interview opportunity. What if I want to change careers?
You didn't locate the problem correctly. . First, you are trained, that is, you have no work experience. Second, you are a secondary school student, without a college diploma or an undergraduate diploma. It is very unlikely that someone will call you. You feel very capable (or have great potential). You can modify your resume and work in a company for one and a half years (in view of your other work experience) to tell what you are doing and what you are responsible for (try to write), so try again. If you really like JAVA, you are not afraid of cheating. . . Also, sign up for a TV university and get a college certificate. It's simple. . . . . Finally, I wish you an early employment.
