Baffling Android Error on Interactive Story App

This is the screen I am getting as an error. Though I've tried as well as possible to follow the video very exactly.

!https://gardenofiden.com/Screenshot%20from%20Android%20Studio.png "'.class' expected"

the code is 

    private void loadPage(int pageNumber) {
        Page page = story.getPage(int pageNumber);

        Drawable image = ContextCompat.getDrawable(this, page.getImageId());
        storyImageView.setImageDrawable(image);

        String pageText = getString(page.getTextID());
        pageText = String.format(pageText, name);
        storyTextView.setText(pageText);
        choice1Button.setText(page.getChoice1().getTextId());
        choice2Button.setText(page.getChoice1().getTextId());
    }

the highlighted expression is pageNumber and the error is '.class' expected followed by another error reading ';' expected there is no mising ';' for sure. Is there a problem how I'm calling story.getPage ?

If there is more of the code you need me to add here please lmk.

remove 'int' inside the parenthesis.

Pages pages = story.getPage(pageNumber);

this will do it.

I took out the offending int and now my error has changed to:

Here is Screen shot: https://gardenofiden.com/Screenshot2020-09-16.png

It appears to be telling me I am giving arguments to new Choice where no arguments are required. Very puzzling. I'm definitely copying the video closely but getting weird errors.

the code for Choice.java is:

package com.idenrosenthal.interactivestory.model;

public class Choice {
    private int textId;
    private int nextPage;

    public int getTextId() {
        return textId;
    }

    public void setTextId(int textId) {
        this.textId = textId;
    }

    public int getNextPage() {
        return nextPage;
    }

    public void setNextPage(int nextPage) {
        this.nextPage = nextPage;
    }
}

and the code for Story.java where the Choice.java is called is:

package com.idenrosenthal.interactivestory.ui;

import com.idenrosenthal.interactivestory.R;
import com.idenrosenthal.interactivestory.model.Choice;
import com.idenrosenthal.interactivestory.model.Page;

public class Story {
    private Page []pages;

    public Story() {
        pages = new Page[7];

        pages[0] = new Page(R.drawable.page0 ,
                R.string.page0 ,
// 1st error here:
                new Choice(R.string.page0_choice1 , 1),
                new Choice(R.string.page0_choice2 , 2));

        pages[1] = new Page(R.drawable.page1,
                R.string.page1,
                new Choice(R.string.page1_choice1, 3),
                new Choice(R.string.page1_choice2, 4));

        pages[2] = new Page(R.drawable.page2,
                R.string.page2,
                new Choice(R.string.page2_choice1, 4),
                new Choice(R.string.page2_choice2, 6));

        pages[3] = new Page(R.drawable.page3,
                R.string.page3,
                new Choice(R.string.page3_choice1, 4),
                new Choice(R.string.page3_choice2, 5));

        pages[4] = new Page(R.drawable.page4,
                R.string.page4,
                new Choice(R.string.page4_choice1, 5),
                new Choice(R.string.page4_choice2, 6));

        pages[5] = new Page(R.drawable.page5, R.string.page5);

        pages[6] = new Page(R.drawable.page6, R.string.page6);
    }



    public Page getPage(int pageNumber) {
        if (pageNumber>=pages.length){
            pageNumber=0;
        }
        return pages[pageNumber];
    }
}
