LibGDX: Is it possible to draw a BitmapFont and update it?

Question

What I try to make is:

1. Draw a BitmapFont on the top of the screen and let it go down to the bottom, where it gets deleted.
2. While that BitmapFont is still making its way down, draw another BitmapFont with different text.
3. Repeat 1 and 2.

Is this achievable with one BitmapFont or do I have to make multiple BitmapFonts in order for this to work?

EDIT:

private BitmapFont font;

 public PlayState(GameStateManager gsm) {
    super(gsm);

    cam.setToOrtho(false, Gdx.graphics.getWidth() / 2, Gdx.graphics.getHeight() / 2);

    // TODO: change the font of the random word

    font = new BitmapFont();
    font.setColor(Color.BLACK);

@Override
public void render(SpriteBatch batch) {
batch.setProjectionMatrix(cam.combined);

    batch.begin();
    for (Rectangle word1 : word.words) {
        font.draw(batch, word.getWordString(), word1.x, word1.y);
    }
    batch.end();
}

word.getWordString() is the text I want to show, which changes with every loop. What it does now is change the text of the newly drawn word that spawns at the top, but also the previous one.

EDIT2:

public class Word {

    public Array<Rectangle> words;

    public Word(){
        words = new Array<Rectangle>();
        spawnWord();
    }

    public void spawnWord() {
       Rectangle word = new Rectangle();
       word.x = MathUtils.random(0, Gdx.graphics.getWidth() / 2 - 64);
       word.y = Gdx.graphics.getHeight();

       words.add(word);
    }

    public String getWordString(){
       return wordString;
    }
}

Answer 1

You are looping over the Rectangle objects in word.words and getting the coordinates from word1 (the object you get from the array) but you call word.getWordString() for them all. The unless you change the value of word.getWordString() inside the loop the string you get will be the same. That is why you have the same string for all your objects.

If you want to have different text on eatch word1 object you need to store them on eatch word1.

Right now it looks like you are just using the Rectangle class to keep track of its position.

If you make a class called Word with a Rectangle and a String on it you can get the result you want.

public class Word{
    private Rectangle bound;
    private String wordString;

    public Word(Rectangle bound, String wordString){
        this.bound = bound;
        this.theWord = wordString;
    }

    public String getWordString(){
        return wordString;
    }

    public Rectangle getBound(){
        return bound;
    }

    public void updateBound(float x, float y){
        bound.x = x;
        bound.y = y;
    }
}

Then store your Word objects in an array called words and loop over them like this:

 batch.begin();
 for (Word word : words) {
    font.draw(batch, word.getWordString(), word.getBound().x, word.getBound.y);
 }
 batch.end();

EDIT1 I made a quick example. pastebin I still can't see how you get your wordString, but this way you store it on every Word object. You don't have to keep track of a String and changing it all the time. You create a Word with a string and thats it. This also make it possible to remove a certain word from the screen or change the text on a specific object.
