1. 샘플 소스

package client;

public class Person 
{
    private final String name;
    private final int age;

    private Person(Builder builder)
    {
        this.name = builder.name;
        this.age = builder.age;
    }

    public static class Builder
    {
        private String name;
        private int age;

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

        public Builder setAge(int age)
        {
            this.age = age;
            return this;
        }

        public Person build()
        {
            return new Person(this);
        }
    }

    public String getName()
    {
        return name;
    }

    public int getAge()
    {
        return age;
    }
   
    public static void main(String[] args){
     Person person = new Person.Builder().setName("미물").setAge(30).build();
     System.out.println(person.getName());
     System.out.println(person.getAge());
