  • Reference type conversions

    Sintaxis de Java
    Nivel 10, Lección 6
    When compatibles types are converted, the conversion may be narrowing or widening. Today, we'll use the Object class as we look at type conversions. Any reference type can be assigned to such a variable (type narrowing). But what if you need to perform a widening conversion? You'll learn in the lesson.

  • Real types

    Sintaxis de Java
    Nivel 10, Lección 7
    You need to get used to working with real types (or floating-point numbers) in Java. Of course, it may be difficult to immediately accept that given float f = 3/5, f is actually zero! It's also unclear how to get the fractional number we need. In fact, all these problems are solved. And quite simply.

  • Literals

    Sintaxis de Java
    Nivel 10, Lección 8
    The word "Literals" provides cover for soldiers on a rather visible front. They penetrate Java code and strike it with their...specificity. All data, as such, arises during execution of a program, but literals are embedded right in the code. "Rain In Spain" is a literal String, and 0.256 is a literal float. And so on. There's nothing complicated about it, but you need to remember this word.

  • Useful Links from the Professor – 10

    Sintaxis de Java
    Nivel 10, Lección 9
    Students frequently don't pay attention the first time they are introduced to type conversion, because most often they read this topic at the very beginning of their study of Java. And the student doesn't know much at that point, and type conversion is "forgotten" until better times. However, at the secret CodeGym center, this topic is presented exactly when it is needed.

  • Nerd break: The Streaming

    Sintaxis de Java
    Nivel 10, Lección 10
    Before tackling the last batch of tasks in not just this level, but in the entire first quest, you deserve a good rest! Then you’ll be ready to finish all that remains. But be prepared to have your nerves jangled by this video. It’s a thriller about going completely crazy for Java, based on a novel by Stephen King. :)

    Nivel 10, Lección 11
    The first quest is coming to an end! This crucial moment is the best time to repeat the material and reinforce your knowledge through practice. Accordingly, in this block we have prepared tasks on various topics, and even several problems that are more advanced. If something isn't clear, you can google it. Think and google, got it?
