The lambda expression is described earlier, but we can see that the lambda expression actually simplifies the writing of a part of the code and is not a very useful language feature. But if the lambda expression fits into the Stream class library described in this article, it will play a huge role. initial knowledge of flow class library As usual, let's take a look at an example. There is a list of integers

Sometimes we can not use the database and the file system to store data, it is necessary to complete the file-based data calculation. However, Java itself lacks the corresponding class library, which requires hard coding to achieve structured file calculations with complex code and poor readability. There are many issues on the web that look for Java class librar
