Question

我正在尝试读取与Java项目位于同一文件夹中的名为Rental.ser的文件，并且我有一个名为Rental的类来将对象存储在其中

public void getInfo() throws IOException,ClassNotFoundException{
 try{ 
    ObjectInputStream is =new ObjectInputStream(new FileInputStream("Rental.ser"));
    System.out.println(is.readObject().getClass()); 
    }
catch(Exception e){
    System.out.println("Error"+e.getMessage());
  e.printStackTrace();

}



}

但是它总是给我错误

java.lang.ClassNotFoundException: Rental

在我打印值的行上我在做什么错了？

从SER文件获取对象。爪哇
