Java 8 Features

 Here are some of the key features introduced in Java 8:


  1. Lambda Expressions: Allow functional programming in Java, provide a way to represent functional interfaces with an expression.

  2. Stream API: Supports functional-style operations on streams of elements, allows operations to be executed in parallel.

  3. Functional Interfaces: Interfaces with only one abstract method, such as java.util.function.Predicate and java.util.function.Function.

  4. Method References: A shorthand syntax for lambda expressions, allowing a method to be passed as an argument without having to invoke it explicitly.

  5. Default Methods in Interfaces: Enable adding new methods to interfaces without breaking existing implementations, methods defined with the "default" keyword.

  6. Optional Class: A container object that may or may not contain a non-null value, used to represent an absent value or null with an alternative approach.

  7. Nashorn, JavaScript Engine: A high-performance JavaScript runtime, providing better performance for applications that use JavaScript.

  8. Date Time API: A comprehensive and improved date and time library, replacing the existing java.util.Date and java.util.Calendar classes.

  9. Parallel Array Sorting: Sorting of arrays in parallel, enabling improved performance for large data sets.

  10. Base64 Encoding and Decoding: A mechanism for encoding and decoding binary data as a text format, useful for sending binary data over text-based protocols.

Lambda Expressions java 8

Lambda expressions are a feature introduced in Java 8 that allow functional programming in Java. They provide a concise way to represent functional interfaces (interfaces with only one abstract method) using an expression. For example, consider the following functional interface for a single method that takes two integers as inputs and returns an integer:  @FunctionalInterface public interface MathOperation {    int operation(int a, int b); } A lambda expression can be used to implement this functional interface, such as the following addition operation: MathOperation addition = (int a, int b) -> a + b; Here, the lambda expression (int a, int b) -> a + b implements the operation method of the MathOperation functional interface. The expression takes two integer inputs a and b and returns their sum. Lambda expressions can be used to pass behavior as a method argument, for example, with a method that takes a MathOperation argument and applies it to two integer inpu...

Introduction to Java

Introduction to Java: Java is an object-oriented, class-based, and widely used programming language. It was developed by James Gosling at Sun Microsystems (now owned by Oracle Corporation) in the mid-1990s. Java is known for its "write once, run anywhere" capability, meaning code written on one platform can run on any device that has a Java Virtual Machine (JVM) installed. Java is used to develop a variety of applications, including mobile, web, desktop, and games.  History: Java was first released in 1995 as a part of Sun Microsystems' Java platform. It was designed to provide a platform-independent programming language for consumer electronic devices like televisions and cable boxes. The language was later adapted for use in developing web applications and eventually became one of the most widely used programming languages in the world. In 2010, Oracle Corporation acquired Sun Microsystems and became the owner of Java. Since then, Java has undergone several updates and ...

Java Generics: Understanding and Using Parameterized Types

Generics are a powerful feature of Java that allow you to write code that is type-safe and reusable. Generics allow you to write code that can work with multiple types, rather than being tied to a specific type. What are Generics in Java? Generics in Java are a feature that allows you to write code that can work with multiple types. Generics allow you to write code that is type-safe and reusable, as it is not tied to a specific type. Why Use Generics? Type-Safety : Generics ensure that your code is type-safe, as it can work with multiple types, rather than being tied to a specific type. Reusability : Generics allow you to write code that is reusable, as it can work with multiple types, rather than being tied to a specific type. Improved Readability : Generics help to make your code more readable, as you can clearly define the types that your code works with. How to Use Generics To use generics in Java, you must specify the type that your code should work with in angle brackets ( < a...
