如何为特定对象复制通用对象的内容

public class ShallowCopyExample implements Cloneable {
    private int[] data;

    public ShallowCopyExample() {
        data = new int[]{1, 2, 3};
    }

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

    public static void main(String[] args) throws CloneNotSupportedException {
        ShallowCopyExample original = new ShallowCopyExample();
        ShallowCopyExample copy = (ShallowCopyExample) original.clone();

        // 修改原对象的数组
        original.data[0] = 99;

        // 输出两个对象的数组
        System.out.println(Arrays.toString(original.data)); // [99, 2, 3]
        System.out.println(Arrays.toString(copy.data));    // [99, 2, 3]
    }
}

import java.io.*;

public class DeepCopyExample implements Serializable {
    private int[] data;

    public DeepCopyExample() {
        data = new int[]{1, 2, 3};
    }

    public DeepCopyExample deepCopy() throws IOException, ClassNotFoundException {
        // 序列化
        ByteArrayOutputStream bos = new ByteArrayOutputStream();
        ObjectOutputStream oos = new ObjectOutputStream(bos);
        oos.writeObject(this);

        // 反序列化
        ByteArrayInputStream bis = new ByteArrayInputStream(bos.toByteArray());
        ObjectInputStream ois = new ObjectInputStream(bis);
        return (DeepCopyExample) ois.readObject();
    }

    public static void main(String[] args) throws IOException, ClassNotFoundException {
        DeepCopyExample original = new DeepCopyExample();
        DeepCopyExample copy = original.deepCopy();

        // 修改原对象的数组
        original.data[0] = 99;

        // 输出两个对象的数组
        System.out.println(Arrays.toString(original.data)); // [99, 2, 3]
        System.out.println(Arrays.toString(copy.data));    // [1, 2, 3]
