It is best to simply disable this inspection, either for your whole project or for a specific class. Put your cursor on the warning and press &lt;kbd&gt;Alt&lt;/kbd&gt; + &lt;kbd&gt;Enter&lt;/kbd&gt; to bring up the following menu, which allows you to disable it:

If you **really** want to use `@SuppressWarnings` you can choose the `Suppress for class` option from the dialog above. This will add the following annotation:

    @SuppressWarnings(&quot;WeakerAccess&quot;)

I&#39;m learning jQuery using visual studio and testing my code in Chrome browser. This is my HTML code

    &lt;!DOCTYPE html&gt;
    &lt;html xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;
    &lt;head&gt;

        &lt;script type=&quot;text/javascript&quot;&gt;
            $(window).load(function () {

why $(window).load() is not working in jQuery?

I am not using DI and simply want to invoke a DbContext from within my controller. I am struggling to figure out what the &#39;options&#39; should be?

ApplicationDbContext.cs

        public class ApplicationDbContext : IdentityDbContext&lt;ApplicationUser&gt;
    {

        public DbSet&lt;Gig&gt; Gigs { get; set; }
        public DbSet&lt;Genre&gt; Genres { get; set; }


        public ApplicationDbContext(DbContextOptions&lt;ApplicationDbContext&gt; options)
            : base(options)
        {
        }

        protected override void OnModelCreating(ModelBuilder builder)
        {
            base.OnModelCreating(builder);
            // Customize the ASP.NET Identity model and override the defaults if needed.
            // For example, you can rename the ASP.NET Identity table names and more.
            // Add your customizations after calling base.OnModelCreating(builder);
        }
    }

GigsController.cs

        public class GigsController : Controller
    {
        private ApplicationDbContext _context;

        public GigsController()
        {
            _context = new ApplicationDbContext();
        }


        public IActionResult Create()
        {
            var viewModel = new GigFormViewModel
            {
                Genres = _context.Genres.ToList()
            };


            return View(viewModel);
        }
    }

The issue is stemming in my GigsController constructor:

    _context = new ApplicationDbContext();

I am erroring out because I need to pass something into the ApplicationDbContext. There is no argument given that corresponds to the required formal parameter &#39;options&#39; of &#39;ApplicationDbContext.ApplicationDbContext(DbContextOptions&lt;ApplicationDbContext&gt;)&#39;	

I tried creating a default constructor in ApplicationDbContext derived from base(), but that didn&#39;t work either.

In my startup.cs, I have configured the ApplicationDbContext

            public void ConfigureServices(IServiceCollection services)
        {
            // Add framework services.
            services.AddDbContext&lt;ApplicationDbContext&gt;(options =&gt;
                options.UseSqlServer(Configuration.GetConnectionString(&quot;DefaultConnection&quot;)));

            services.AddIdentity&lt;ApplicationUser, IdentityRole&gt;()
                .AddEntityFrameworkStores&lt;ApplicationDbContext&gt;()
                .AddDefaultTokenProviders();

            services.AddMvc();

            // Add application services.
            services.AddTransient&lt;IEmailSender, AuthMessageSender&gt;();
            services.AddTransient&lt;ISmsSender, AuthMessageSender&gt;();
        }

I keep getting annoyed by the &quot;Can be private&quot; warning, however my `FirebaseRecyclerAdapter` will not work in that case. So, is there a `@SuppressWarnings` for that?

**What I&#39;ve tried:**

`@SuppressWarnings(&quot;all&quot;)` but that&#39;s not what I want.

**Note:** I am using Android Studio

What value for @SuppressWarnings do I use to suppress the &quot;Can be private&quot; warning?

I keep getting annoyed by the "Can be private" warning, however my <code>FirebaseRecyclerAdapter</code> will not work in that case. So, is there a <code>@SuppressWarnings</code> for that?

I am trying to launch Mozilla but still I am getting this error:

&gt;Exception in thread &quot;main&quot; java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.gecko.driver system property; for more information, see https://github.com/mozilla/geckodriver.

I am using `Selenium 3.0.01` Beta version and `Mozilla 45`. I have tried with `Mozilla 47` too. but still the same thing.

I had originally written an `ArrayList` and stored unique values (usernames, i.e. `Strings`) in it. I later needed to use the `ArrayList` to search if a user existed in it. That&#39;s `O(n)` for the search.

My tech lead wanted me to change that to a `HashMap` and store the usernames as keys in the array and values as empty `Strings`.

So, in Java - 

    hashmap.put(&quot;johndoe&quot;,&quot;&quot;);

I can see if this user exists later by running - 

    hashmap.containsKey(&quot;johndoe&quot;); 

This is `O(1)` right?

My lead said this was a more efficient way to do this and it made sense to me, but it just seemed a bit off to put null/empty  as values in the hashmap and store elements in it as keys.

My question is, is this a good approach? The efficiency beats `ArrayList#contains` or an array search in general. It works.
My worry is, I haven&#39;t seen anyone else do this after a search. I may be missing an obvious issue somewhere but I can&#39;t see it.

Is it a good idea to store data as keys in HashMap with empty/null values?

If we use Java 8 Stream like `list.stream().filter(....).collect(..).....` When is it closed this stream? 

Is it good practice that we close the stream us as the next example?

    Stream&lt;String&gt; stream = list.stream();
    String result = stream.limit(10).collect(Collectors.joining(&quot;&quot;));
    stream.close();

According to the documetation of [`JsonNode`](https://fasterxml.github.io/jackson-databind/javadoc/2.2.0/com/fasterxml/jackson/databind/JsonNode.html):

&gt; Most mutators, however, need to be accessed through specific sub-classes (such as [`ObjectNode`](https://fasterxml.github.io/jackson-databind/javadoc/2.5/com/fasterxml/jackson/databind/node/ObjectNode.html)  and ArrayNode).


However I am still confused since some stackoverflow answers seem to use them quite interchangeably. What different purpose do they serve?


What is the difference between ObjectNode and JsonNode in Jackson?

PyCharm provides some helpful warnings on code style, conventions and logical gotchas. It also provides a notification if I try to commit code with warnings (or errors).

Sometimes I consciously ignore these warnings for particular lines of code (for various reasons, typically to account for implementation details of third-party libraries). I want to suppress the warning, but just for that line (if the warning crops up on a different line where I&#39;m not being deliberate, I want to know about it!)

How can I do that in PyCharm? (Following a universal Python convention strongly preferable.)
