被引用对象

public class BaseInfo implements Cloneable{

    private String CompanyName;

    public BaseInfo() {
    }
    @Override
    protected BaseInfo clone() throws CloneNotSupportedException {
        return ((BaseInfo) super.clone());

需要实例化的对象

public class Product implements Cloneable{

    private String part2;
    private Integer part3;
    private Integer part4;
    private Integer part5;
    private BaseInfo part6;

    }

    @Override
    protected Product clone() throws CloneNotSupportedException {
        Product clone = (Product) super.clone();
        BaseInfo clone1 = this.part6.clone();
        clone.setPart6(clone1);
        return clone;
    }

    @Override
    public String toString() {
        return super.hashCode()+"Product{" +
                "part1='" + part1 + '\'' +
                ", part2='" + part2 + '\'' +
                ", part3=" + part3 +

                ", part6=" + part6 +
                '}';
    }

    public Product() {
    }

    public Product(String part1, String part2, Integer part3, Integer part4, Integer part5,BaseInfo part6) {
        this.part1 = part1;

    }

    public void setPart1(String part1) {
        this.part1 = part1;
    }

    public String getPart2() {

    public static void main(String[] args) throws CloneNotSupportedException {
        BaseInfo baseInfo = new BaseInfo("123");
        Product product = new Product("1", "2", 3, 4, 5,baseInfo);
        Product clone = product.clone();
        System.out.println(clone);
