  2. Boxing (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Boxing_(computer_programming)

    Unboxing the object also returns a copy of the stored value. Repeated boxing and unboxing of objects can have a severe performance impact, because boxing dynamically allocates new objects and unboxing (if the boxed value is no longer used) then makes them eligible for garbage collection. However, modern garbage collectors such as the default ...

  3. Type conversion - Wikipedia

    en.wikipedia.org/wiki/Type_conversion

    Some programming languages allow compilers to provide coercion; others require it. In a mixed-type expression, data of one or more subtypes can be converted to a supertype as needed at runtime so that the program will run correctly. For example, the following is legal C language code:

  4. Primitive data type - Wikipedia

    en.wikipedia.org/wiki/Primitive_data_type

    Some languages, though, may implicitly convert Booleans to numeric types at times to give extended semantics to Booleans and Boolean expressions or to achieve backwards compatibility with earlier versions of the language. For example, early versions of the C programming language that followed ANSI C and its former standards did not have a ...

  6. List of Java bytecode instructions - Wikipedia

    en.wikipedia.org/wiki/List_of_Java_bytecode...

    This is a list of the instructions that make up the Java bytecode, an abstract machine language that is ultimately executed by the Java virtual machine. [1] The Java bytecode is generated from languages running on the Java Platform, most notably the Java programming language.

  7. Comparison of Java and C++ - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_Java_and_C++

    The differences between the programming languages C++ and Java can be traced to their heritage, as they have different design goals.. C++ was designed for systems and applications programming (i.e., infrastructure programming), extending the procedural programming language C, which was designed for efficient execution.

  8. Type signature - Wikipedia

    en.wikipedia.org/wiki/Type_signature

    In the Java virtual machine, internal type signatures are used to identify methods and classes at the level of the virtual machine code.. Example: The method String String. substring (int, int) is represented in bytecode as Ljava / lang / String. substring (II) Ljava / lang / String;.

  9. Extension method - Wikipedia

    en.wikipedia.org/wiki/Extension_method

    The modified object is often a class, a prototype, or a type. Extension methods are features of some object-oriented programming languages. There is no syntactic difference between calling an extension method and calling a method declared in the type definition. [1] Not all languages implement extension methods in an equally safe manner, however.
