永恒错误java.io.StreamCorruptedException：无效的类型代码：AC

Question

我搜索了论坛并尝试了不同的方法，但我仍然遇到此错误。会发生的是它只读取输入流中的一个值，然后程序关闭，我得到错误。我不明白为什么它不起作用。

这是代码：

public void readRecords() {
    Players records;

    try { // input the values from the file
        Object obj = null;
        while (!(obj = (Players) input.readObject()).equals(null)) { //line 60
            records = (Players) obj;
            myArr.add(records);

            System.out.printf("DEBUG: %-10d%-12s\n", records.getScores(), records.getName());
        }
        input.close();
    } // end try
    catch (EOFException endOfFileException) {
        return; // end of file was reached
    } catch (ClassNotFoundException classNotFoundException) {
        System.err.println("Unable to create object.");
    } catch (IOException ioException) {
        System.err.println("Error during reading from file.");
        ioException.printStackTrace();
    }
}

这是错误：

Error during reading from file.
