Simple examples of commonly used chained call methods in Java and Android, javaandroid

This example describes the commonly used method of chained call in Java and Android. We will share this with you for your reference. The details are as follows:

Recently, many open-source frameworks in the fire have recently used a "(method ). (method ). (method) ", the most typical is RxJava. The source code of the AlertDialog control in android is also in this form. We can see that it is calledChain call. "Action is the only criterion for testing procedures" 0.0! After checking and speaking so much, you still have to write an example and run the expected results.

/***** Chained call ** @ author k. k **/public class Student {public Student () {} public static Builder builder () {return new Builder ();} // static internal class static class Builder {/* name */private String name;/* age */private String age;/* grade */private String grade; /* student ID */private String no;/* Major */private String Professional; public String getName () {return name;} public Builder setName (String name) {this. name = name; return this;} public String getAge () {return age;} public Builder setAge (String age) {this. age = age; return this;} public String getGrade () {return grade;} public Builder setGrade (String grade) {this. grade = grade; return this;} public String getNo () {return no;} public Builder setNo (String no) {this. no = no; return this;} public String getProfessional () {return Professional;} public Builder setProfessional (String professional) {Professional = professional; return this;} public void showMessagwe () {System. out. println ("name:" + this. name); System. out. println ("Age:" + this. age); System. out. println ("class:" + this. grade); System. out. println ("student ID:" + this. no); System. out. println ("professional:" + this. professional) ;}} public static void main (String [] args) {// chained call (simple code, strong readability) Student. builder (). setName ("always intended for attackers "). setAge ("23 "). setGrade ("Junior "). setNo ("20110310 "). setProfessional ("Information Management and Information System "). showMessagwe ();}}
