Is there a way to have a parameter for a method be of type Method() somehow?

Okay, so I have restructured my program to work more efficiently with serialization and saving the files the way I want...but now I need to be able to deserialize the object and use it to get the Class's getter methods. So in my FileIO class I have created a serialize() method, and a few deSerialize() methods with parameters to meet the needs of my program...minus one that would help tremendously. So, here is an example of what I want to do...but it doesn't work with the way I have it setup...I don't even know if it's possible so if it is how would I write the parameter??

Code:

---

public void deSerialize( String pFileName, Cabinet pObject, JTextField txf, Method pMethod )
  {                                    // my question is about this parameter ^^^^^^^^^^^^^^
     
      try
      {
        Cabinet cabinet;
        File file = new File( pFileName + ".dat" );
       
        FileInputStream inStream = new FileInputStream( file );
        ObjectInputStream objectInputFile = new ObjectInputStream( inStream );
        cabinet = ( Cabinet ) objectInputFile.readObject();
        txf.setText( String.valueOf( cabinet.pMethod() ) );
        // This is where the parameter needs to be ^, otherwise I have to make one of these methods for each
        // method call I want and just write the method in there without it being a variable.
        inStream.close();
        objectInputFile.close();
      }
     
      catch( FileNotFoundException e )
      {
       
      }
     
      catch( IOException e )
      {
       
      }
     
      catch( ClassNotFoundException e )
      {
       
      }
  }

Read the API doc for the Method class.
The parameter variable: pMethod is an instance of Method. It is not the name of a method in a class.
To call the method represented by this variable is different than the way you are trying to do it.

I just used that as an example, that is my question. What do I replace Method with to make pMethod work?

Create an interface with pMethod() defined.
Have the classes that you want to pass to the deSerialize() method implement that method.
