New features java 8

Java 8, released in 2014, introduced several new features that improved the language and its ecosystem. Here are some of the most notable ones:

  1. Lambda Expressions: Lambda expressions are a concise way to represent functions or methods. They can be used to simplify code and make it more expressive.
  2. Method References: Method references are a shorthand way to refer to methods. They can be used to simplify code and make it more readable.
  3. Functional Programming: Java 8 introduced functional programming concepts such as map, filter, and reduce, which can be used to process data in a more declarative way.
  4. Optional Class: The Optional class is a container that may or may not contain a non-null value. It can be used to handle null pointer exceptions in a more elegant way.
  5. Stream API: The Stream API is a new way to process data in Java. It allows you to create streams from collections, arrays, or other sources, and then perform operations on those streams.
  6. Date and Time API: The Date and Time API is a new way to work with dates and times in Java. It provides a more intuitive and flexible way to work with dates and times.
  7. Nashorn JavaScript Engine: Nashorn is a new JavaScript engine that is included with Java 8. It allows you to run JavaScript code in a Java environment.
  8. JavaFX: JavaFX is a new GUI library that is included with Java 8. It provides a more modern and flexible way to build graphical user interfaces.
  9. Type Annotations: Type annotations are a new way to add metadata to Java code. They can be used to provide additional information about the types of variables, method parameters, and return types.
  10. Repeatable Annotations: Repeatable annotations are a new way to define annotations that can be repeated multiple times on the same element.
  11. Method Hiding: Method hiding is a new feature that allows you to hide a method from a superclass. This can be useful when you want to provide a different implementation of a method in a subclass.
  12. Default Methods: Default methods are a new feature that allows you to add new methods to an interface. This can be useful when you want to provide a default implementation for a method in an interface.
  13. Functional Interfaces: Functional interfaces are a new way to define interfaces that can be used with lambda expressions. They must have only one abstract method.
  14. Local Variable Type Inference: Local variable type inference is a new feature that allows you to declare local variables without specifying their types. The type of the variable is inferred from the assignment.
  15. Multi-Catch Blocks: Multi-catch blocks are a new feature that allows you to catch multiple exceptions in a single catch block.
  16. Try-With-Resources: Try-with-resources is a new feature that allows you to use resources in a try block without having to manually close them.
  17. Improved Error Handling: Java 8 provides improved error handling features, including better support for checked exceptions and improved error messages.
  18. Improved Performance: Java 8 provides improved performance features, including better support for parallel processing and improved garbage collection.

These are just a few of the many new features and improvements that were introduced in Java 8.
