A simple example of implementing chained operations (method chains) in Java

Simple with chained programming

Student

 PackageJetty;ImportJava.util.stream.IntStream;/*** @Auther: Xiao Yu * @Date: Created in 14:52 2018/3/22*/ Public classStudent {PrivateInteger ID; PrivateInteger age; PrivateString name; PrivateString address; PrivateString Happy;  PublicStudent getId () {System.out.println ( This.
