What are the key subjects that have been included in the Java SE 11 Developer Certification?

The key topics added are:

• Java Platform Module System (JPMS)
• Local variable type inference
• Secure Coding in Java SE Application
• Annotations

The Java Platform Module System (JPMS) is a new feature introduced in Java 9 that allows developers to create more modular and secure applications. It allows you to define and manage modules, which are self-contained units of code that encapsulate a set of related functionalities. This helps in reducing dependencies between different parts of the code and provides better encapsulation and organization.

Local variable type inference is another new feature introduced in Java 10 that allows developers to declare variables without explicitly stating their types. Instead, the compiler can infer the type of the variable based on the value assigned to it. This helps in writing more concise and readable code.

Secure Coding in Java SE Application refers to practices and techniques used to write code that is resistant to vulnerabilities and exploits. This includes using secure coding patterns, avoiding hardcoded credentials, sanitizing user input, and handling exceptions properly.

Annotations in Java are a mechanism for adding metadata or extra information to code. They can be used to provide additional information to the compiler, perform compile-time checks, or specify behavior at runtime. Annotations are commonly used for writing unit tests, configuring dependencies, and creating custom annotations for custom logic.
