我刚接触Java。 我目前正在制作游戏，并且正在尝试创建一种方法来保存和加载我创建的对象。 这是我的做法。
我有Bob类并扩展了Character并实现了Serializable。 我想写入文件的对象是 “鲍勃”
我尝试了一个空白对象，它可以工作。但是，有了这个“ bob”对象，它就会以某种方式出错。 我不知道为什么。 有什么问题吗？
public class Main implements Serializable {
static Character Bob= new Bob();
static Character James= new James();
public static void main(String[] args) {
try {
ObjectOutputStream out = new ObjectOutputStream(new FileOutputStream("Members.txt"));
out.writeObject(bob);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

答案 0 :(得分：0)
这可能是因为您将变量bob声明为Character类型而不是Bob类型。您可以尝试声明它为Bob类型吗？或者使您的超类可序列化（在这种情况下，您不必使Bob可以序列化）
