Java 如何提示用户指定写入和读取序列化文件的名称？

我试图提示用户为写入和读取序列化文件创建名称。例如，我可以做以下工作吗：

System.out.print("What would you like to name your file?");
String fileName = scanner.nextLine;

try{
 ObjectOutput ostream = new ObjectOutputStream(new FileOutputStream(fileName)) // Would this create a file with the name inputted by the user? If so what would be the extension for the file?

 ostream.writeObject(//whatever I want to put in here)

 //close

//catch

try{

 ObjectInputStream = new ObjectInputStream(new FileInputStream(fileName))

//catch

---

如果要从终端提示用户输入内容，最简单的方法可能是使用java.io.Console，尤其是其中一种readLine方法：

请参阅。

请将代码分块，以便可读。欢迎使用so！没有运行代码示例的不清楚问题在这里很少受到关注。考虑张贴，包括你试图写文件等。你的意思是命名文件之前，序列化，然后再次去序列化同名？？？？

import java.io.Console;

...

Console console = System.console();
if (console == null) {
  throw new IllegalStateException("No console to read input from!");
}

String fileName = console.readLine("What would you like to name your file? ");
// Whatever the user inputed is now in fileName
