JDK10

JDK10, released in March 2018, is the tenth major release of the Java Development Kit (JDK) by Oracle Corporation. It introduced several new features and enhancements to the Java programming language and its runtime environment. One of the key features of JDK10 is local-variable type inference, which allows developers to declare local variables with the var keyword, letting the compiler infer the type based on the assigned value. This feature aims to reduce boilerplate code and improve code readability.

Another notable addition is the garbage-collector interface, which provides a common interface for implementing garbage collectors. This allows for more flexible and customizable memory management in Java applications.

JDK10 also includes improvements to the Java Virtual Machine (JVM), such as the application class-data sharing feature, which allows multiple JVM instances to share class metadata, reducing memory usage and improving startup time. Additionally, the JVM now supports parallel full garbage collections, which can improve performance for applications with large heaps.

In terms of security, JDK10 includes several enhancements to the Java Cryptography Architecture (JCA) and Java Cryptography Extension (JCE), providing stronger cryptographic algorithms and improved security for Java applications.

Overall, JDK10 builds upon the foundations laid by previous versions of the JDK, introducing new features and enhancements that improve the performance, security, and developer experience of Java applications.
