Java SE 11 Developer 1Zo-819 course
Becoming Java certified is a great way to help improve your career options with more job opportunities and more pay.
That’s because Oracle’s Java certification program, unlike many other certifications out there, has real value in the industry. One of the main reasons is that it’s an official Oracle certification, but second, the exam is quite difficult to pass.
Employers see programmers who are Java certified as more valuable than programmers who are not certified. So it’s totally worth getting Java certified to take advantage of this.

Who is this course suitable for?
If you have been through at least some of my Java Masterclass on Udemy, or another Java course and/or have some professional programming experience in Java or another programming language then this course is for you. But note, that it’s a prerequisite that you have taken my 1Z0-819 Part 1 course on Udemy before attempting this one.
This course is definitely NOT for beginner programmers. If you are a beginner, you will struggle with this course. In that case, grab my Java Masterclass and go through all or a significant amount of that course, and then my 1Z0-819 Part 1 course, before attempting this course.
