Lambda Expressions

Lambda-Expressions

Lambda expressions are a powerful feature introduced in Java SE 8 that allow developers to implement single-method interfaces in a concise and expressive manner. They enable the creation of anonymous functions, which can be used to simplify code, particularly when working with functional programming concepts. By reducing boilerplate code associated with anonymous classes, lambda expressions enhance readability and maintainability. The syntax typically involves the use of the lambda operator (->) to define the function’s parameters and body. Lambda expressions are especially useful in conjunction with the Stream API and JavaFX, making them a valuable tool for modern Java programming.
