Introduction to Lambdas in Java
Lambdas are a powerful addition to the Java language, introduced in Java 8, that allow developers to write more concise and readable code by representing functionality as a method argument or code block. In this post, we'll provide a complete introduction to lambdas in Java, including what they are, how they work, and some common use cases. What are Lambdas? In Java, a lambda expression is a short block of code that represents a method implementation. Lambdas provide a concise way to write code that can be passed around as a method argument or stored in a variable. Lambdas are often used in functional programming to represent behavior as data. Here's an example of a lambda expression in Java: Function<Integer, Integer> square = x -> x * x; This code defines a lambda expression that takes an integer as input, squares it, and returns the result. The lambda is assigned to a variable of type Function<Integer, Integer> , which represents a function that takes an ...
