鉴于这一小部分代码:

import java.util.Arrays;

public class Sample {
    private final int test;

    private Sample(int test) {
        this.test = test;
    }

    public static void main(String[] args) {
        System.out.println(Arrays.toString(Hello.class.getDeclaredConstructors()));
    }

    public static class Hello {
        private final int i;

        private Hello(int i) {
            this.i = i;
        }

        public int getI() {
            return i;
        }

        public static class Builder {
            private int i;

            private Builder() {

            }

            public static Builder builder() {
                return new Builder();
            }

            public void add(int i) {
                this.i = i; …
