Java鏈式調用

最近發現項目中很多代碼在對象賦值的時候還是一個一個的set,代碼量一多，感覺好low。然后想到用鏈式調用減少點代碼量。下面是一個簡單例子

public class Person {
    
    private String name;
    private int age;
    private String address;
    
    public Person setAge(int age) {
        this.age = age;
        return this;
    }

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

    public Person setAddress(String address) {
        this.address = address;
        return this;
    }
    
    public void build(){
        System.out.println("今年"+this.age+"歲,坐標"+this.address+",可以叫我"+this.name);
    }
    
    public static void main(String[] args) {
        new Person().setAddress("知春路").setName("xxxx").setAge(23).build();
    }

}
