通过ObjectOutputStream将LinkedList写入文本文件但输出是垃圾

当我尝试将链接列表的内容写入文本文件时，出现输出错误

    try {
        FileOutputStream out = new FileOutputStream("ValidMovesMatrix.txt");
        ObjectOutputStream oout = new ObjectOutputStream(out);
        oout.writeObject("--+ This will show all the VALID moves A* algorithm has taken to come up with the solution +---");
        oout.writeObject(" ");
        for (int matrixIdx = 0; matrixIdx < matrixStack.size(); matrixIdx++) {
            Object matrixShow = matrixStack.get(matrixIdx);
            oout.writeObject(matrixShow);
        }
        oout.close();
    } catch (Exception ex) {
        System.out.println("Output error");
    }

它没有打印我的链接列表的内容，并且输出文本文件包含以下垃圾：

ObjectOutputStream将对象写入序列化字节代码格式，以便以后可以重新读取。

如果您想要文本输出，请使用PrintStream or PrintWriter并实施Matrix.toString()写每个Matrix作为格式化文本。
