What are the applications of lambda in Java?

  1. Set operations: Using lambda expressions can simplify the traversal and manipulation of collections, such as filtering, sorting, mapping, etc.
  2. Thread processing: Using lambda expressions makes it easy to create anonymous inner classes for handling thread tasks.
  3. GUI programming: In frameworks like Swing or JavaFX, using lambda expressions can simplify the writing of event listeners.
  4. Lambda expressions are commonly used to implement functional interfaces, simplifying code and improving readability.
  5. With the introduction of Java 8, Stream API allows for easy functional operations on collections, combined with lambda expressions for more flexible data processing.
  6. Sorting and filtering: Sorting and filtering operations can be easily implemented through lambda expressions, such as using the Comparator interface to customize the sorting of collections.
  7. Concurrency handling: Java 8 introduced features such as CompletableFuture and ParallelStream to streamline concurrent programming, making it easier to handle concurrent tasks by utilizing lambda expressions.

In general, lambda expressions in Java can be applied in various scenarios to streamline code, enhance readability, and handle data and concurrent tasks more flexibly.
