The advantages and application scenarios of Lambda expressions in Java
The Lambda expression introduced in Java 8 is an important language feature that makes the code more concise , easy to read, easy to maintain, and provides a simpler way to deal with functional programming. This article will introduce the advantages and common application scenarios of Lambda expressions, and give specific code examples.
1. Advantages of Lambda expressions
The advantage of Lambda expressions is that it allows us to use less code to achieve the same function, thereby improving development efficiency. The following are some advantages of Lambda expressions:
2. Application scenarios of Lambda expressions
Runnable r = () -> { System.out.println("Hello, Lambda!"); };
Listlist = Arrays.asList("Java", "Python", "C++"); list.forEach(item -> System.out.println(item));
Thread t = new Thread(() -> { System.out.println("Running in a new thread!"); }); t.start();
Listlist = Arrays.asList("Java", "Python", "C++"); Collections.sort(list, (a, b) -> { return a.compareTo(b); });
The above are some common application scenarios of Lambda expressions in Java. By using Lambda expressions, we can write more concise and readable code, improving code maintainability and development efficiency.
Summary
Lambda expressions are an important feature introduced in Java 8 that can make the code more concise and readable, and provide a more concise way to deal with functional programming. This article introduces the advantages and common application scenarios of Lambda expressions, and gives corresponding code examples. I hope that readers will have an understanding of Lambda expressions through the introduction of this article and can flexibly apply them in actual development.
