Java 13

Each new Java version brings several new features and improvements. These can include:

1. New language features: These might include new syntax, new ways of doing things, and improvements to existing features.

2. Performance improvements: Every new Java version tries to make applications run faster and more efficiently. This can include improvements to the JVM (Java Virtual Machine), the garbage collector, and other areas.

3. API improvements and additions: New versions often add new classes and methods to the standard Java API, giving developers more tools to work with.

4. Removed or deprecated features: Sometimes, old features are removed or deprecated to make way for new ones, or because they’re no longer needed.
