![]() * Note that the JLS probably also says a lot about NPEs indirectly. Method references of the form name1::name2 or primaryExpression::name throws a NullPointerException when evaluated when name1 or primaryExpression evaluates to null.Ī note from the JLS here says that, someInstance.someStaticMethod() doesn't throw an NPE, because someStaticMethod is static, but someInstance::someStaticMethod still throw an NPE! In the most trivial cases, the compiler will catch the problem and let you know that " num may not have been initialized," but sometimes you may write code that does not directly create the object.įor instance, you may have a method as follows: public void doSomething(SomeObject obj) (whether its an expression or statement) can throw a NullPointerException when foo is null.įoo.new SomeInnerClass() throws a NullPointerException when foo is null. If you attempt to dereference num before creating the object you get a NullPointerException. In the second line, the new keyword is used to instantiate (or create) an object of type Integer, and the reference variable num is assigned to that Integer object. Since you have not yet said what to point to, Java sets it to null. The first line declares a variable named num, but it does not actually contain a reference value yet. ![]() So you have a reference to something that does not actually exist. The NullPointerException (NPE) typically occurs when you declare a variable but did not create an object and assign it to the variable before trying to use the contents of the variable. If a reference variable is set to null either explicitly by you or through Java automatically, and you attempt to dereference it you get a NullPointerException. You can get a null value in a reference variable if you explicitly set it that way, or a reference variable is uninitialized and the compiler does not catch it (Java will automatically set the variable to null). Reference variables can be set to null which means " I am referencing nothing". Now here is where things get interesting. All primitives have to be initialized to a usable value before they are manipulated. These two lines will crash the program because no value is specified for x and we are trying to use x's value to specify y. For example variables of type Object are references.Ĭonsider the following code where you declare a variable of primitive type int and don't initialize it: int x By convention reference types are usually denoted with a type that starts in uppercase. to access a method or field, or using [ to index an array. If you want to manipulate the Object that a reference variable refers to you must dereference it. References: variables that contain the memory address of an Object i.e. For example variables of type int or char are primitives. By convention primitive types start with a lowercase letter. If you want to manipulate the data in a primitive variable you can manipulate that variable directly. There are two overarching types of variables in Java:

![]() So how do you know which Spanish tenses to learn first?Īs a beginner, you only need to worry about mastering the three basic tenses: simple present, past, and future.

After unification, the Italian government initially encouraged emigration to relieve economic pressures in the South. These were largely agricultural and overpopulated regions, where much of the populace had been impoverished by centuries of foreign misrule, and an oppressive taxation system imposed on the South after Italian unification in 1861. Īpproximately 84% of the Italian immigrants came from Southern Italy and Sicily. Further immigration would be greatly limited by a number of restrictive laws passed by Congress in the 1920s. This period of large scale immigration ended abruptly with the onset of the First World War in 1914 and, except for one year (1922), never resumed. The 1870s were followed by the greatest surge of immigration, which occurred in the period between 18 and brought more than 4 million Italians to America. ![]() Immigration began in earnest during the 1870s, when more than twice as many Italians immigrated (1870–79: 46,296) than during the five previous decades altogether (1820–69: 22,627). Ībout 5.5 million Italians immigrated to the United States from 1820 to 2004. Italian Americans are the fourth largest European ethnic group in the United States (not including American ethnicity, an ethnonym used by many in the United States overall, Italian Americans rank seventh, behind German American, Irish American, African American, English American, American, and Mexican American). Italian Americans ( Italian : italoamericani or italo-americani ) are an ethnic group comprising Americans who have full or partial ancestry from Italy, especially those who identify with that ancestry, along with their cultural characteristics.

Although the clocks developed under the program will not be quite as as the best optical clocks found in a lab, they will surpass current state-of-the-art atomic clocks in both precision and holdover while maintaining low SWaP in a robust package. If the satellites' GPS signals were jammed by an adversary, time synchronization would rapidly deteriorate and thereby threaten military operations.ĭARPA officials state that ROCkN will leverage DARPA-funded research from the last several decades that has seen demonstration of the world’s most precise optical atomic clocks.

That’s why it’s important for parents to have some disciplinary standards and model good social transactions. But it’s better still that they come to an understanding of why these things are important in their own home with the adults that are already in their lives. ![]() It’s one thing to tell a child that when they get into kindergarten they need to pay attention, listen to the teacher, and behave themselves. “It’s making a child able to function.”Ĭontext is also important for the social and emotional skills children need to know before heading into kindergarten. “All of this is functional,” Smerling says. It all shows the power of numbers in context. Eventually, the marbles can be tallied and exchanged for a treat or a toy. The same concept can be accomplished by collecting marbles in a jar, one for every time a child does something right. ![]() To foster this idea, she suggests parents collect pennies with their kid, counting them and exchanging them for other coins or treats. We pay for things with money identified by numbers.” “I think kids should know how to recognize money, because that’s an exchange,” Smerling explains. To help things along, Smerling encourages parents to point out words, whether they be in the pages of a book or on business signs on Main Street.Ĭontext is key for numbers as well. This is one of the reasons parents reading with kids is such a key to literacy. But it’s more important that a child be able to recognize that the alphabet is made up of letters, and that letters form words, and that those words can create stories. It’s not an abstract stage of life: It’s a very concrete stage of life.” “That experience should have to do with what’s going on in their world, and learning how to function in the world. “The first five years of a child’s life should be experiential,” explains family therapist and former kindergarten teacher Kathryn Smerling, Ph.D. In fact, a seemingly impressive kid may be behind if they don’t know numbers can aid in a transaction or that letters create a book. Just because a 5-year-old knows the capital of Vermont doesn’t mean that he or she understands Montpelier’s historical significance or demographics (or needs to). So whether they’re academically a little ahead or a little behind, everyone’s going to know their letters, numbers, and colors by the time they head towards the numbered grades.Īnother reason the memorization of digits, letters, animal names or state capitals makes no difference in kindergarten is because knowledge doesn’t count for much without context. One of the reasons an alphabet and centenary of numbers is not necessarily helpful is because every kid will come into kindergarten with wildly different levels of knowledge based on where they went to pre-k. ![]() ![]() Yes, that sounds harsh, but there are reasons for that assessment: The list of skills children need to succeed in their early childhood education is relatively short and doesn’t include rote memorization. But neither of those kids actually have skills that are particularly useful for kindergarten, or life. A 4-year-old who can count accurately to 100 is pretty impressive. A preschooler who knows their ABCs from the alphabet song is adorable. ![]() ![]() Click + Add section, and then select a section to insert into your contact page.From the dropdown menu, click Pages > Contact to load the contact page template.Find the theme that you want to edit, and then click Customize.From your Shopify admin, go to Online Store > Themes.If your screen is smaller than 1600 pixels, then they appear on the left side.

But, beyond that, the browser itself has various security susceptibilities since it uses outdated cryptography and SSL protocols. First of all, it's based in China, a country known for lack of online privacy and freedom. Protection isn’t the only thing you need to worry about while using UC Browser, but also your privacy. Unsurprisingly, while browsing some users' comments about the browser, many complained about getting viruses on their mobile phones after using UC. There is no way that we can feel secure using UC Browser without having an excellent antivirus backing us up. However, the biggest problem is that our antivirus not only showed a warning every time we opened the browser but blocked a few links due to malware as well. Nothing strange since UC is not the only browser in the industry that makes money by recommending a handful of sites on its home page. When we opened the browser, it showed a home page with various websites to visit. Right off the bat, that was a bad omen, but we continued to push forward. This is where UC Browser falls on its face and makes you wonder if faster speeds and a few nice features are worth your privacy and protection.įor this review, we installed the desktop version of UC Browser, which we had to install from a third-party website since our antivirus blocked the download page from the official website. Moreover, since UC is a Chromium browser, it's compatible with most extensions from the Chrome Web Store. Fortunately, UC Browser asks you to enable the ad blocker through a pop-up the first time you come across an ad the other extensions can be easily enabled/disabled to the right of the address bar. ![]() Speaking of YouTube, UC Browser comes with a nice feature that lets you open any video in a small window and display it on the front of the screen, allowing you to browse other pages or even open different applications with the video still playing in front of you – excellent for multitasking.Īlthough the default extensions come installed, they don't come enabled. However, contrary to Brave, it's not possible to download videos directly from YouTube. Last, but not least, it also comes with the UC Resource Hunter, which lets you download videos, images, and music from the web. On top of that, it comes with an image previewer that lets you see full-size images without clicking, as well as the Microsoft Cloud extension. It also comes with Avast SafePrice, which will find you the best prices and discount coupons while shopping online. ![]() ![]() By default, it comes with the Avast extension installed, which is going to be essential while using UC. UC Browser comes with some neat built-in features. If the antivirus blocking on UC Browser's download page is not enough of a red flag, maybe knowing that it was caught stealing personal data from an unknown server in China is enough for you to think twice before installing it. Sounds amazing, right? Unfortunately, when it comes to user privacy and protection, the UC Browser leaves a lot to be desired. On top of that, it also comes with a built-in ad blocker. Moreover, this Chinese browser, owned by Alibaba Group, is exceptionally user-friendly, providing you with mouse gestures on the desktop version to quickly browse through pages. Due to its overall fast speeds, how nicely it handles simultaneous downloads, and the number of useful features, UC Browser is one of the most popular web browsers for Android, especially in Asia. |
