Is there a way to modify the Java class name to consist of two separate words?

(Edited) I am completely new to android app development. My question is: How can I rename a java class with two words instead of one?

My main menu consists of 3 options, each linked to a java class:

public class Menu extends ListActivity{

    String classes[] = { "Report","Study","Contact",};

To change the names displayed on my main menu, I need to modify the corresponding java class name. For example, I want the first option to be displayed as [Report Odor] instead of just [Report].

I attempted the following approach: I right-clicked on the class and chose "Refactor->Rename". However, this method throws an error if I try to add a space between the two words.

Am I proceeding correctly with this task? Any assistance would be greatly appreciated. Regards. Here is the complete code for my main menu: package com.reportodor.mohamed;

import android.app.ListActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class Menu extends ListActivity{

String displayNames[] = { "Report Odor","Study","Contact",};
Class activities[] = {Report.class, Study.class, Contact.class};

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setListAdapter(new ArrayAdapter<String>(Menu.this, android.R.layout.simple_list_item_1, displayNames));
}

@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
    // TODO Auto-generated method stub
    super.onListItemClick(l, v, position, id);
    String selection = displayNames[position];
    try{
    Class ourClass = Class.forName("com.reportodor.mohamed." + selection);
    Intent intent = new Intent(Menu.this, ourClass);
    startActivity(intent);
    }catch (ClassNotFoundException e){
        e.printStackTrace();
    }
}

Is it possible to modify the name of a Java class to consist of two words?

If you are referring to having a space in the class name, that is not supported by Java (or most other programming languages).

I need to update the names on my main menu by changing the corresponding Java class names.

No, the user-visible display name shown in your ListView does not have to match the Java class name.

For instance:

String displayNames[] = { "Report Odor","Study","Contact"};
Class activities[] = {Report.class, Study.class, Contact.class};

Your ArrayAdapter for your ListActivity should display the displayNames. When onItemClick() is triggered, it should find the matching Class in activities based on the position and construct an Intent to launch that activity.

Please note that assuming these classes are activities. If not, the same principle applies but with some variations in implementation details.
