  2. Comparison of programming languages (string functions)

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

    For function that manipulate strings, modern object-oriented languages, like C# and Java have immutable strings and return a copy (in newly allocated dynamic memory), while others, like C manipulate the original string unless the programmer copies data to a new string.

  3. Comparison of Java and C++ - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_Java_and_C++

    The C++ standard library is designed to be minimalistic, providing only a standardised set of general use features, while the Java Class Library and Java Platform Module System (the Java standard library) is much more extensive, providing a much larger comprehensive standardised set of features, such as graphics, UI creation, and more.

  4. Three-way comparison - Wikipedia

    en.wikipedia.org/wiki/Three-way_comparison

    Many object-oriented programming languages have a three-way comparison function, which performs a three-way comparison between the object and another given object. For example, in Java, any class that implements the Comparable interface has a compareTo method which either returns a negative integer, zero, or a positive integer, or throws a ...

  5. Comparison of programming languages - Wikipedia

    The Computer Language Benchmarks Game site warns against over-generalizing from benchmark data, but contains a large number of micro-benchmarks of reader-contributed code snippets, with an interface that generates various charts and tables comparing specific programming languages and types of tests.

  6. Java performance - Wikipedia

    en.wikipedia.org/wiki/Java_performance

    Java memory use is much higher than C++'s memory use because: There is an overhead of 8 bytes for each object and 12 bytes for each array [61] in Java. If the size of an object is not a multiple of 8 bytes, it is rounded up to next multiple of 8. This means an object holding one byte field occupies 16 bytes and needs a 4-byte reference.

    However, the compiler automatically transforms the code so that the list will "silently" receive objects, while the source code only mentions primitive values. For example, the programmer can now write list. add (3) and think as if the int 3 were added to the list; but, the compiler will have actually transformed the line into list. add (new ...

    The only point is they are not from a single vendor. May be a vendor like SUN can provide CPPSDK. C++ language is still evolving and the version C++ 0X is awaited. If you compare JAVA EJB's with C++ equivalents, you have Tuxedo ATMI and CORBA from BEA systems. You have to pay for that, which is rock solid. Here the inout parameters are allowed.

  9. Object model - Wikipedia

    en.wikipedia.org/wiki/Object_model

    Object reference Objects can be accessed via object references. To invoke a method in an object, the object reference and method name are given, together with any arguments. Interfaces An interface provides a definition of the signature of a set of methods without specifying their implementation.
