之前，我們有以下課程public class Checklist {    private final long id;    private String text;    private boolean checked;    public Checklist(long id) {        this.id = id;    }    public String getText() {        return text;    }    public void setText(String text) {        this.text = text;    }    public boolean isChecked() {        return checked;    }    public void setChecked(boolean checked) {        this.checked = checked;    }    public long getId() {        return id;    }}以下 json 操作（字符串到對象）效果很好。String string = "[{\"checked\":false,\"id\":0,\"text\":\"Boodschappen\"},{\"checked\":false,\"id\":1,\"text\":\"Melk\"}]";GsonBuilder builder = new GsonBuilder();final Gson gson = builder.create();List<Checklist> checklists = gson.fromJson(string, new TypeToken<List<Checklist>>() {}.getType());for (Checklist checklist : checklists) {    System.out.println("--> " + checklist.getText());}現在，我們將該類“升級”到以下級別，以節省磁盤空間。public class Checklist {    @SerializedName("i")    private final long id;    @SerializedName("t")    private String text;    @SerializedName("c")    private boolean checked;    public Checklist(long id) {        this.id = id;    }    public String getText() {        return text;    }    public void setText(String text) {        this.text = text;    }    public boolean isChecked() {        return checked;    }    public void setChecked(boolean checked) {        this.checked = checked;    }    public long getId() {        return id;    }}但是，我們仍然希望能夠將舊的 json 字符串轉換回新的對象。String oldString = "[{\"checked\":false,\"id\":0,\"text\":\"Boodschappen\"},{\"checked\":false,\"id\":1,\"text\":\"Melk\"}]";我可以知道如何才能實現這一目標嗎？
