            @Override
            public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {
                switch (menuItem.getItemId()){
                    case R.id.dash:
                    startActivity(new Intent(getApplicationContext()
                            ,dash.class));
                    overridePendingTransition(0,0);
                    return true;
                    case R.id.home:
                        return true;
                    case R.id.notifications:
                        startActivity(new Intent(getApplicationContext()
                                ,notifications.class));
                        overridePendingTransition(0,0);
                        return true;

                }
                return false;
            }
        });

    }

From your explanation in the comments I am guessing that you want to change your R.string folder at run-time. Which is not possible. In fact the entire res folder cannot be modified at run-time.

If you want to change the menu titles at runtime

menu = mynavigationview.getMenu()  //mynavigationview is the name of your navigationcomponent
MenuItem menuitem = menu.getItem(*insert item index here*);  //menu is the menu here 
menuitem.setTitle("Your title");

This should work. If you want to keep the titles stored then you should use shared preferences to do so and set them from the preferences each time your application is launched.

First you need to get your navigationView with findViewById(R.id.nav_view_id), then:

Menu menu = navigationView.getMenu();
MenuItem item = menu.findItem(R.id.your_menuItem_id);
// or MenuItem item = menu.getItem(0) if you have one MenuItem

Then you create a method in which you will choose which title you currently need.

//for example
 protected String getMyTitle(){
    if(/*something*/){
        return getResources().getString(R.id.title_home);
    }else if(/*something*/){
        return getResources().getString(R.id.title_dashboard);
    }else{
        return getResources().getString(R.id.title_notifications);
    }
}

And as a result, we put the text in item.

item.setTitle(getMyTitle());
