Alex Mamo is right but then this is how you should pass incase you call it from a model class

public class FirebMessage {
    public String message;
    public String senderPhoneNumber;
    public String receiverPhoneNumber;
    public Map time;

    public FirebMessage() {
    }

    public FirebMessage(String message, String senderPhoneNumber, String receiverPhoneNumber, Map time) {
        this.message = message;
        this.senderPhoneNumber = senderPhoneNumber;
        this.receiverPhoneNumber = receiverPhoneNumber;
        this.time = time;
    }

Then consume as follows

 private void writeNewMessage(String message, String receiver,String sender) {

        FirebMessage firebMessage = new FirebMessage(message, receiver,sender,ServerValue.TIMESTAMP);
        mDatabase.child("messages").push().setValue(firebMessage, new DatabaseReference.CompletionListener() {
            @Override
            public void onComplete(DatabaseError databaseError, DatabaseReference databaseReference) {
                if (databaseError != null) {
                   Log.e(TAG,"Data Not saved");

                } else {
                    Log.e(TAG,"Data saved successfully");
                }
            }
        });
    }
