error: can not find symbol variable toolbar and section_format

0

I'm learning to program for Android and created an app from scratch on an empty screen. Then I decided to put my Activity in a template with tabs, where the first tab would be this screen I already made and the second one I would still program. I created a blank Activity with the tab template and started copying the codes of this new Activity for my project. The problem is that I am now stopped at two errors and I can not solve it. I've looked in various places and nothing.

It's probably something simple for you, but since I'm new, I can not see the problem.

Error: (90, 37) error: can not find symbol variable toolbar and Error: (523, 48) error: can not find symbol variable section_format

MainActivity.java:

mtoolbar = findViewById(R.id.toolbar);
        setSupportActionBar(mtoolbar);
        // Create the adapter that will return a fragment for each of the three
        // primary sections of the activity.
        mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
        mViewPager = (ViewPager) findViewById(R.id.container);
        mViewPager.setAdapter(mSectionsPagerAdapter);
        FloatingActionButton fab = findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
                        .setAction("Action", null).show();
            }
        });
