📄️ Introduction to Java 8
Java 8 introduced several powerful features that make coding easier, cleaner, and more efficient. These features are widely used in modern Java development.
📄️ Lambda Expressions
Lambda Expressions are one of the most important features introduced in Java 8. They allow you to write shorter and more readable code by replacing anonymous classes with concise syntax.
📄️ Streams API
The Streams API is one of the most powerful features introduced in Java 8. It allows you to process collections of data in a functional and declarative way, making your code shorter and more readable.
📄️ Default and Static Methods in Interfaces
Java 8 introduced Default Methods and Static Methods in interfaces, making interfaces more flexible and powerful. These features allow you to add new methods to interfaces without breaking existing implementations.
📄️ Optional Class
The Optional class was introduced in Java 8 to address the common issue of NullPointerException. It provides a way to handle null values safely and explicitly, making your code more robust and readable.
📄️ New Date and Time API
Java 8 introduced a completely new Date and Time API in the java.time package. This API replaces the outdated and error-prone Date and Calendar classes, providing a modern, intuitive, and thread-safe way to handle dates and times.
📄️ Real-World Examples
Now that we’ve covered the key features of Java 8, let’s see how they can be applied in real-world scenarios. These examples demonstrate how to combine multiple Java 8 features like Lambda Expressions, Streams API, and Optional to solve practical problems.
