1Z0-811 exam is a foundational level exam for those that have completed the Java Foundations, Java Fundamentals, Java Programming I training or the Java Coding and Concepts MOOC. Passing this exam gives the certification credential demonstrating your understanding of the Java programming language and concepts. And, that you know how to write and execute a Java program, work with the Java Development Kit (JDK) and the Java Runtime Environment (JRE). Earning the Java Foundations Certified Junior Associate credential arms you with the fundamentals of Java programming, enabling you to demonstrate both conceptual knowledge and skills. Certification also validates your capabilities to a future employer, showing your potential to become an increasingly valuable asset to any company as you progress into OCA level during your early stage of employment, and later to OCP.
This exam does not require any hands-on professional experience with Java, but to be successful you will need a basic understanding of Java programming language and concepts and have mathematical, logical, and analytical problem-solving skills. In addition, you must know how to write and execute a Java program and work with the Java Development kit (JDK) and the Java Runtime Environment (JRE).
This certification is focused on students in secondary schools, two-year colleges and four-year colleges and universities who have participated in the Oracle Academy program and/or are studying computer science including relevant Java curricula and faculty members who teach foundational Java and computer, science classes.
