        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        toolbar = findViewById(R.id.Tool_bar);

You have the problem in the declaration of setSupporActionBar .

You are declaring a toolbar that comes from android.widget.Toolbar and that type of toolbar can not be assigned to setSupporActionBar .

To solve the error you need to remove the import of android.widget.Toolbar and import android.support.v7.widget.Toolbar which is what you need in this case.

As you can see in the image, it is the error of the one that alerts you to android studio.
