Lambda expressions simplify the development of functional programming constructs in Java.\n\n### L02_Functional_Interface\nFocuses on functional interfaces, which are interfaces with a single abstract method. Includes the `@FunctionalInterface` annotation and explains their critical role in enabling lambda expressions.\n\n### L03_Method_References\nCovers method references, which are a shorthand notation for lambdas to refer to methods or constructors. Includes examples of:\n- Static method references (`ClassName::staticMethod`)\n- Instance method references (`instance::instanceMethod`)\n- Constructor references (`ClassName::new`)\n\n### L04_Optional_Class\nExplains the `Optional` class, a container object used to handle potential null values gracefully. Demonstrates methods like `orElse`, `isPresent`, and `ifPresent` to avoid `NullPointerException`.\n\n### L05_Default_and_Static_method_in_Interface\nDetails how Java 8 allows interfaces to include:\n- **Default methods**: Methods with a default implementation.\n- **Static methods**: Utility methods that can be called without an instance of the interface.\n\n### L06_Java8_Stream_APIs\nExplores the powerful Stream API for processing collections and sequences of data in a functional style. Includes examples of:\n- Intermediate operations like `filter`, `map`, and `sorted`.\n- Terminal operations like `collect`, `forEach`, and `reduce`.\n\n### L07_BiFunction_BiConsumer_BiPredicate  \nExplores the utility of `BiFunction`, `BiConsumer`, and `BiPredicate` functional interfaces for handling operations involving two inputs. Includes examples of:  \n- **`BiFunction`**: For applying a function to two arguments and producing a result.  \n- **`BiConsumer`**: For performing an operation that accepts two arguments but returns no result.  \n- **`BiPredicate`**: For evaluating a condition with two arguments and returning a boolean.  \n\n## How to Use This Repository\nEach folder contains:\n- **Code Examples**: Demonstrates how to implement and use the feature in real-world scenarios.\n- **Documentation**: Provides detailed explanations of the concepts and their applications.\n\n---\n\nExplore these features to harness the full potential of Java 8 for writing modern, concise, and efficient code.\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fathrocks%2Fjava-8-stream-api","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fathrocks%2Fjava-8-stream-api","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fathrocks%2Fjava-8-stream-api/lists"}
