1Z0-815 | Java SE 11 Programmer I

Java SE 11 Programmer I (1Z0-815) Exam tutorial

Java SE 11 Programmer I (1Z0-815) Exam will help the candidates to move one step forward in becoming an Oracle Certified Professional: Java SE 11 Developer. However, this exam will help candidates to gain skills in modular programming and secure coding management. Candidates must have the knowledge of all the latest new features and functionality in Java technology. This exam will demonstrate the candidates:

Proficiency in Java
Broad knowledge of Java programming language
Good coding practices
Understanding of new features since Java SE 8

However, this exam is best for entry-level programmers who are new to Java and need to learn concepts, language constructs, and data types. In this exam, the programmers should know how to apply language skills for developing programs using the latest major versions of the JDK, currently Java 11.

Java SE: New Features

Java SE: Exploiting Modularity and Other New Features introduces the Java module system and other new features that include JShell, convenience methods, new techniques for working with streams, and managing deprecated APIs. However, these features were introduced in versions after Java 8, and therefore new to developers migrating to Java 11. With this, the candidates will learn to create secure, portable, high-performance applications. Further, they will also learn about:

Designing applications for accessing the module system and reliable configuration, improved security and performance, and more easily scalable applications.
Migrating existing applications to modular applications in a step-by-step manner, choosing which parts of the application to migrate first.
Dealing with common problems encountered in migrating an application, including, cyclic dependencies and split packages.
Creating multi-release JAR files that can be run on different Java releases.
Using convenience methods for reducing code that seems verbose, inefficient or boilerplate, and increasing readability.
Using JShell for quickly running small code experiments and testing new APIs.

Exam Policies

Oracle Certification provides detailed information on exam policies to help candidates understand about the terms and procedures. Candidates studying for the Oracle 1Z0-815 exam should first go through these exam policies and get information about after the exam or before exam procedures. Some of them include:

Cancellation Policy

If a candidate wants to cancel or reschedule an exam then they should go to pearsonvue.com/oracle and login to their account. There just select one of the options on the right of the page: Reschedule a Test or Cancel a Test. However, the candidates who do not appear for a scheduled exam will forfeit the full exam fee. If the exam fee is paid with a voucher then the number of the voucher will be invalidated for future use.

Exam Retake Policy

Candidates who want to retake the exam must wait 14 days before retaking a failed proctored exam. However, they can retake an online non-proctored exam at any time. But, they cannot retake a passed exam at any time. Candidates are only allowed 4 attempts to pass an exam in a 12-month period.
