Cost & certification notes
Java SE 21 Developer Professional ( 1Z0-830 ) is the long-term Java SE professional credential on this page, and public exam references list its price at $245. Exam-prep sites also list a newer Java SE 25 Developer Professional exam (1Z0-831), so check Oracle MyLearn for its status and price;
because Oracle pricing can vary by country, tax and delivery region, verify the final amount in Oracle MyLearn before purchase.
Older Java 8, 11 and 17 credentials are retained here because they remain useful when your employer's production estate uses those Java versions. Oracle retires and replaces exams from time to time, so the Java 8, Java EE 7 and WebLogic 12c exams may no longer be bookable; confirm before planning.
This page intentionally separates Java SE certifications from ecosystem skills such as Spring Boot, Kafka and Kubernetes, which are important career skills but are not Oracle Java SE certifications.
