  2. Java syntax - Wikipedia

    en.wikipedia.org/wiki/Java_syntax

    A snippet of Java code with keywords highlighted in bold blue font. The syntax of Java is the set of rules defining how a Java program is written and interpreted. The syntax is mostly derived from C and C++. Unlike C++, Java has no global functions or variables, but has data members which are also regarded as global variables.

  3. Comparison of programming languages by type system

    en.wikipedia.org/wiki/Comparison_of_programming...

    This is a comparison of the features of the type systems and type checking of multiple programming languages.. Brief definitions A nominal type system means that the language decides whether types are compatible and/or equivalent based on explicit declarations and names.

  4. Static import - Wikipedia

    en.wikipedia.org/wiki/Static_import

    Static import is a feature introduced in the Java programming language that allows members (fields and methods) which have been scoped within their container class as public static, to be used in Java code without specifying the class in which the field has been defined.

  5. static (keyword) - Wikipedia

    en.wikipedia.org/wiki/Static_(keyword)

    static is a reserved word in many programming languages to modify a declaration. The effect of the keyword varies depending on the details of the specific programming language, most commonly used to modify the lifetime (as a static variable) and visibility (depending on linkage), or to specify a class member instead of an instance member in classes.

  6. Static variable - Wikipedia

    en.wikipedia.org/wiki/Static_variable

    In computer programming, a static variable is a variable that has been allocated "statically", meaning that its lifetime (or "extent") is the entire run of the program. This is in contrast to shorter-lived automatic variables, whose storage is stack allocated and deallocated on the call stack; and in contrast to dynamically allocated objects, whose storage is allocated and deallocated in heap ...

  7. Naming convention (programming) - Wikipedia

    en.wikipedia.org/.../Naming_convention_(programming)

    Java compilers do not enforce these rules, but failing to follow them may result in confusion and erroneous code. For example, widget.expand() and Widget.expand() imply significantly different behaviours: widget.expand() implies an invocation to method expand() in an instance named widget , whereas Widget.expand() implies an invocation to ...

  8. Comparison of C Sharp and Java - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_C_Sharp_and_Java

    As a result, code in the inner class has access to both the static and non-static members of the outer class. To create an instance of a non-static inner class, the instance of the embracing outer class must be named. [53] This is done via a new new-operator introduced in JDK 1.3: outerClassInstance.new Outer.InnerClass(). This can be done in ...

  9. Type safety - Wikipedia

    en.wikipedia.org/wiki/Type_safety

    The Java language is designed to enforce type safety. Anything in Java happens inside an object and each object is an instance of a class. To implement the type safety enforcement, each object, before usage, needs to be allocated. Java allows usage of primitive types but only inside properly allocated objects.
