JAVA中实现链式操作（方法链）的简单例子

使用链式编程带来的简单

student

package jetty;

import java.util.stream.IntStream;

/**
 * @Auther: Xiao Yu
 * @Date: Created in 14:52 2018/3/22
 */
public class Student {
    private Integer id;
    private Integer age;
    private String  name;
    private  String  address;
    private  String  happy;

    public Student getId() {
        System.out.println(this.id);
        return  this;
    }

    public Student setId(Integer id) {
        this.id = id;
        return  this;
    }

    public Student getAge() {
        System.out.println(this.age);
        return  this;
    }

    public Student setAge(Integer age) {
        this.age = age;
        return  this;
    }

    public Student getName() {
        System.out.println(this.name);
        return  this;
    }

    public Student setName(String name) {
        this.name = name;
        return  this;
    }

    public Student getAddress() {
        System.out.println(this.address);
        return  this;
    }

    public Student setAddress(String address) {
        this.address = address;
        return  this;
    }

    public Student getHappy() {
        System.out.println(this.happy);
        return  this;
    }

    public Student setHappy(String happy) {
        this.happy = happy;
        return  this;
    }
}

Test

package jetty;

/**
 * @Auther: Xiao Yu
 * @Date: Created in 14:52 2018/3/22
 */
public class Test {
    public static void main(String[] args) {
        Student stu = new Student();
        stu.setId(1).setAge(12).setName("小红").setAddress("北京").setHappy("高兴");
        stu.getId().getAge().getName().getAddress().getHappy();
    }
}
