I'm very confused on how to add the black keys do I do the same for how I did the white keys??? They said that I need to make a new method for it but i dont know what to put. :( please help, thank you.

 
    private String [] names = {"q","w","e","r","t","y","u","i","o","p","[","]"};
    private String [] whiteNotes= {"3c","3d","3e","3f","3g","3a","3g","4c","4d","4e","4f","4g"};
    
    /**
     * Make the piano.
     */
    public Piano()
    {
        super(800,340,1);
       
        for(int k=0; k<names.length; k++){
            Key key = new Key(names[k] , whiteNotes[k] );
            addObject(key, 50+k*63,140);    
        
            }
  
        
     
       



    }
    public void makeKeys()
    {
        
    }
}

Refactoring what you currently have (starting at line 7 above), you have this:

public Piano()
{
    super(800,340,1);
    makeWhiteKeys();

}

private void makeWhiteKeys()
{
    for (int k=0; k<names.length; k++)
    {
        Key key = new Key(names[k] , whiteNotes[k] );
        addObject(key, 50+k*63, 140);
    }
}

You can create another method, very similar to makeWhiteKeys, for making the black keys and call it from line 5.
