That is a very vague question. So the answer is Yes.

public class Message {
}

public class MessageAcceptor {
  public static void accept(Message message) {
   System.out.println("I accept the message " + message);
  }
}

So, what are you really asking?

This kind of statement comes across as bit rude.  Please use a less
demanding tone.

In Java, classes can accept messages, for reasonable definitions of the
word "message".

    String.getClass().getName();

sends the message "getName" to the class object for String.  One could
also call static methods a message that a class will accept.

Normally however, it's an object that takes the message.

    String s = "Hello World\n";
    s = s.trim();

sends the message "trim" to the String object "s".

(In object oriented design that I'm familiar with, a "message" is
normally implemented with a method.  Other forms of dispatch might
exist, although I can't think of any off the top of my head.)

I presume you mean this is the Smalltalk sense.

Of course.  All it means is can your execute a method on an object
with parameters.
